January 14-February 6: We will be looking at principles about lines and angles this month, using GeoGebra. If you are working from home, you will want to load GeoGebra onto your computer. It is free! Download the program at [] The PrIme version is for elementary students. You will want to use the regular version of the program.

On January 14 and 16, we looked at the properties of lines. How can you find the point or points that are part of the solution of two equations? Open GeoGebra by clicking on its icon (it looks like a necklace) Notice that there is a part of the screen for coordinate graphing, another part (on the right) that tells you algebraically what is graphed, and an IMPUT line at the bottom of the page. Part A. After the word INPUT, type: y = 3x + 1 Press ENTER. You will see the graph for this equation on the screen. Next, type y = -2x + 3 Press Enter. You will see two lines graphed on the screen. Do these two lines cross? Do they cross in one place, or more than one place? The place where they cross is the point that will satisfy both equations! Click the arrow at the top left of the screen. Then, touch one line, and then the other line. Each line should become darker as you touch it. After the second line is touched, a point should appear where the lines cross. The name of the ordered pair should also appear at the left of the screen. What is the ordered pair?
 * You will investigate finding the solution of two equations this by graphing them using GeoGebra.**
 * You can find the exact coordinates (x,y) for those points by doing the following:**

Save your file. Go to FILE -> SAVE AS -> and then save the file to your desktop as yournameline1.ggb If you are working from home, you should post this on your project page when you are done with this assignment. Part B Go to FILE and then to NEW. Then, After the word INPUT, type: y = 2x - 3 and press ENTER Next, type: 2y = 4x - 6 and press ENTER. What do you see? If you are working from home, type in on your PROJECT page what you see. This is an example of **two equations occupying the same space. They are really two different names for the same line.** These lines have everything in common, and so their intersection has **INFINITE SOLUTIONS**! If you are working from home, save this picture as YOURNAMELine2.ggb, and put it on your project page. Part C Go to FILE and then to NEW. Type in the following equations, one at a time, on the INPUT line: y = 2x - 4 Press ENTER Then, type in another equation: y = 2x + 1 Press ENTER What do you see? Do these lines have any points in common? If you are working from home, save this drawing as YOUR NAMEline3.ggb, and post it on your project page. Also describe what you see. Do these lines ever intersect? Hint: These lines are parallel. They have the same slope (2, the number before the x), but have different y intercepts (the number after the x, in this case, either -4 or 1). On January 23 we looked at Inequalities: Open the file below. You must have GeoGebra installed to view and work with it!
 * Details
 * [[file:Inequalities.ggb|Download]]
 * 2 KB

Once the file is opened, look at the inequalities listed on the left side of the screen. You will see: y = 5x y <= 2x y > 2x You will not be able to see the graphs of these inequalities because the small circle in front of each one is turned off. Click on the circle in front of y < 2x. Notice that the line for the equation y = 2x is dotted, not solid. It is dotted because the inequality is y < 2x, not y < and equal to 2x. Also notice that the graph below the dotted line is shaded in (pink), since y __is less than__ 2x. Now, unclick that first circle, and click on the circle in front of y >= 5x. Notice that the line for y = 5x is solid, since the inequality is y > and equal to 5x. Also notice that the graph above the solid line is shaded in (blue), since y is greater than 5x. PROBLEMS TO TURN IN FOR CREDIT: Now click on the first circle again. Do you see that violet area shaded in-between the pink and blue areas? Points in that area satisfy __both__ inequalities! 1.Find an ordered pair (x,y) that satisfies y< 2x, 2. Another pair that satisfies only y > = 5x, and 3. An ordered pair that satisfies both inequalities! Unclick the first two circles, and look at the third inequality: y < = 2x. 4. Find an ordered pair that satisfies this inequality! Now, unclick the third inequality, and click the circle in front of the fourth one: y > 2x. Do you remember why the line is dotted? 5. Explain why the line is dotted. Email your answers to problems 1-5 to your tech teacher!

January 28-30: During these classes, we looked at both Complementary and Supplementary Angles: Open this file or open the applet below: Look at the larger angle. How large is it? What is another name for this type of angle?

Now, move point C. Notice how the angle measures of the two angles that make up the larger 90 degree angle change. They still always add up to 90 degrees. These pairs of angles are __Complementary angles__. If you only have one of these two angles, how do you find the other one? You could read them off the screen, but what if you did not have this program open? You could use a protractor to get the angle measures, but what if you did not have a protractor? What would you do?

What happens to the sum? 2. What can you conclude about the sum of the interior (inside) angles of a triangle? 3. If you only knew two of the three angle measures, how could you find the third angle measure? Email your tech teacher with your answers for credit!

February 25-March 6:

During the next few weeks, we are going to be carefully looking at and applying the principles of the Pythagorean theorem.

This theorem is credited to Pythagoras, a Greek philosopher who lived about 2500 years ago. He was the leader of a religious cult that looked or mathematical principles in everyday life. He has been given credit for discovering this theorem, but it may have been discovered by one of his followers. Actually, historians say that the ancient Babylonians, Indians, and Chinese knew about this theorem long before Pythagoras was even born!

Open GeoGebra. Get rid of the AXIS on the screen by going to VIEW. Click on the first option, AXIS. The x-y AXIS grid will disappear.
 * To begin this lesson:**

Next, construct three triangles: One equilateral, one a right triangle, and one an obtuse triangle. Click on the tiny red arrow found at the lower right of that picture. Several options will appear. Select the second option, REGULAR POLYGON.
 * To make the equilateral triangle,** Select the polygon tool, found fifth from the left at the upper row of pictured tools.

Then, click on the screen at two places to make two points, A and B. A window will appear, asking you how many vertices (or sides) the polygon should have. Erase 4, and put 3. Click OK. An equilateral triangle will appear.


 * To make the** **right triangle:**

Go to the fifth tool on the top right. It looks like an angle. Select the second option under that tool. It is called ANGLE WITH GIVEN SIZE. Click two points on the screen (C and D). A window will pop up asking you what size angle to make. Erase 45 and put 90. __Change the construction from counterclockwise to clockwise.__ Click OK.

You will see three points on the screen, C, D, and E. Connect these points to make a right triangle.: Go to the segment connection tool, found under the third tool at the top right. Select the second option, SEGMENT BETWEEN TWO POINTS.

Use this tool to connect points C, D, and E, making a right triangle, a triangle with a 90 degree angle!


 * To make an obtuse triangle:**

Go to the fifth tool on the top right. It looks like an angle. Select the second option under that tool. It is called ANGLE WITH GIVEN SIZE. Click two points on the screen (F and G).

A window will pop up asking you what size angle to make.

Erase 45 and put 120.

__Change the construction from counterclockwise to clockwise.__

Click OK.

You will see three points on the screen, F, G, and H.

Connect these points to make an obtuse triangle.:

Go to the segment connection tool, found under the third tool at the top right. Select the second option, SEGMENT BETWEEN TWO POINTS.

Use this tool to connect points F, G, and H, making an __obtuse triangle__, one with an angle that is larger than 90 degrees!


 * __Now, find the lengths of each side of all three triangles:__**

Under the same tool used to make the angles (fifth from the right) is the option **DISTANCE OR LENGTH** Click on the little red arrow on the picture of the angle, and select DISTANCE OR LENGTH. It is the third option down.

Now, click on each side of all three triangles. A number will appear next to each side, which is the length of that side. Notice that the equilateral triangle will have all sides the same length, so there is no smallest side or largest side!

Put your results in the table below. For the equilateral triangle, just fill in columns a, b, and c with the same number:

To fill out the rest of the table, you will need to use a calculator. The a squared column should be filled in with the answer you get when you multiply the smallest side length by itself. For example, if the smallest side has length 5, you would find 5 times 5, and put 25 in the **a squared** column for that row.
 * ||  ||   ||   || **a squared** || **b squared** || **c squared** || **a squared + b squared** ||
 * || **a** || **b** || **c** || **a times a** || **b times b** || **c times c** ||  ||
 * **Largest angle**
 * of triangle** || **smallest side** || **Middle length side** || **Largest side** || **Smallest**
 * side squared** || **Middle side squared** || **Largest side squared** ||  ||
 * **60 degrees**
 * (equilateral** **triangle)** ||  ||   ||   ||   ||   ||   ||   ||
 * **90 degrees**
 * (right triangle)** ||  ||   ||   ||   ||   ||   ||   ||
 * **120 degrees**
 * (obtuse triangle)** ||  ||   ||   ||   ||   ||   ||   ||

Do the same thing for the other sides and triangles.

Then, add the numbers you got for a squared to the numbers you got for b squared for each triangle. Put that result in the last column, **a squared + b squared**.


 * ANALYSIS:**


 * Look at your results. Are there any triangles in which the columns "c squared" and "a squared + b squared" are equal?**


 * If you are working from home, send me a print out of your chart, as well as your findings!**


 * __Congratulations! You have rediscovered the Pythagorean Theorem!__**

This theorem is very important, both to mathematicians, and to students. You will be asked questions about it over and over again, in tests such as the OAA, and later in high school and college exit and entrance tests.

To be certain that you know it, next week we will work on doing application problems about the Pythagorean Theorem. Meanwhile, celebrate your completion of this long lesson by watching the video below, from the old movie, The Wizard of Oz, in which the scarecrow gets confused about the Pythagorean Theorem:

January 7-9, 2013:
Check out these websites for school newpapers using Weebly as their web host:

[]

[]

[]

How are they different from what we are doing? How are they the same? Do you get any ideas for future issues from looking at these virtual newspapers?


 * If you are one of the editors of the newspaper, you will work this week on selecting items to include in next week's issue of the Virtual Newspaper. **


 * If you have not finished your project for submission, you MUST get it done this week! The grading period ends next week! **


 * After your project is done, and editing is done, you will begin to learn how to use Audacity, an audio recording program. **

Using Audacity

**You can record instruments, singing, sound effects, or even speech using Audacity.**

 * __ To begin, read the instructions below, found at eHow.com: __**

[]

= How to Record Using Audacity (from eHow.com) =

“Audacity is a home recording program that you can use for free on [|your PC] to record multi-track audio pieces. Whether it's music, an Internet "radio show" or a podcast, Audacity is a great place to start with your own experimentation in the world of audio recording.”

Instructions
“Install Audacity on your computer”… The program itself is free and you can install it by downloading it at

[]

If you have problems downloading Audacity at home, contact your instructor.

(The school tech lab computers already have Audacity downloaded on them.)

“Connect your hardware. A multi-track digital audio recording program is nothing without a microphone to record with. Almost all PC's have a microphone jack, and this will be what you use for your main audio input. A good, uni-directional microphone is best for most purposes, and your local electronics store will most likely have a selection of several.”

(The school lab computers do not have microphones attached. Your instructor will bring a microphone to school to use.)

… “Once you have the microphone hooked up and set in place, you're ready to record.”

“Record a track on Audacity. Open Audacity on your PC. Look at the control panel on the top of the screen. From left to right, **the double backward arrow** button takes you to the beginning of the track, the **forward arrow is** **PLAY**, the **red circle is** **RECORD**, the **double blue lines are** **PAUSE**, the **yellow box is** **STOP**, and the **double forward arrow takes you to the end of the** **track**. Turn the volume down on your speakers, and press **RECORD**. The reason you turn the volume down is because you will hear yourself in delay while you are recording if you don't. Speak or sing into the microphone. When you are done, press **STOP**."

“Edit your track on Audacity. If you made a small mistake in your recording on Audacity, there is no need to rerecord the entire track. You can edit anything you want on Audacity. Use the slide bar at the bottom of the screen to take you to the area in the recording that you want to edit. Once you've found the section that you want to edit, highlight that section in the track. Once you have the appropriate section highlighted, press the **DELETE** or backspace button, on your keyboard. The section is gone. If you made a mistake in editing, go to the **EDIT** selection in the toolbar at the top of the screen and press **UNDO**."

Add more tracks to your recording. Once you've recorded your first track, you may want to add more layers to your sound. You can record as many additional tracks as you like and line them up however you want. The more you experiment, the more options you'll find you have.

When you finish your recording, save it as a mp3 file on the school desktop. Be sure to label it with your name!

December 3 - 19:

 * For the next few weeks, we will be working with music software and online websites that allow you to make your own musical tracks! **

First, we will be working with the online music-maker, Musicshake!

Go to this online program, found at []

Click **MAKE MUSIC!**


 * You need to first Login using the school Login name //ADAtech8//, and the password. Your teacher will give you the password in class, or will tell it to you via a phone call, if you work from home.**

Then a new screen will pop up: You will see that there are different instruments on the left of the square, while numbers (1,2,3, etc.) stand for different sections of the song. When you click on an instrument, another box will pop up, allowing you to pick instruments, and types of those instruments. The picture below shows what pops up when you click on the guitar:
 * Choose GENRE TEMPO WIZARD**
 * Choose GENRE:** Hiphop, Rock/Metal, R&B, Dance/Disco, Electronic/Techno, Pop, Ballad, Jazz, Latin, Classical/New Age
 * Choose TEMPO:** The faster the tempo, the faster the beats!



After you are done, SAVE YOUR WORK by entering a name for the song in the black box at the top right of the screen.

__You will not be able to download it onto your computer.__

Give the song your first name and last initial and the number one.

For example, my song would be RhondaR1

Then click **SUBMIT** to save your song.

You must tell your teacher the name of the song so that it can be downloaded!

Your teacher will go to the website __later__ to download the class songs and save them to a flashdrive (or email it to you, if you work from home) so that you can use them with your projects.

 * 6) What thing that people do upsets you the most, and why? (No names, please!)

Today, we are going to look at another way to edit photos.

Instead of using a program loaded into your computer, you are going to use an online photo-editing website called **PicMonkey**.

Go to this website by clicking on the link below:

@http://www.picmonkey.com/

On the left of the webpage, you will see a blue square labeled “Edit a photo.”

Click on that square.

A window will open, so that you can choose a file on your computer to edit.

Find one of the pictures you have already saved in your folder on the DESKTOP,

or save a new image into your folder. Be sure you give it a name you will recognize!

Once your photo is loaded, you will see a lot of options to the left of the screen for photo editing.

One, __Automatic,__ adjusts your image by sharpening it and adjusting its brightness.

The other options each have several other photo editing options within them!



The other options are **CROP, ROTATE, EXPOSURE, COLORS, SHARPEN**, and **RESIZE**:


 * CROP** allows you to cut out part of the image. You can make your picture a new special size by specifying a certain number of pixels for length and width, or just a 3x4, 4x5, or 5x5 square.


 * ROTATE** lets you turn the photo around.


 * EXPORTING** lets you adjust the __brightness, highlights, shadows, and contrast__ of your picture.


 * COLORS** allow you to adjust the type and the amount of color in your picture.


 * SHARPEN** allows you to sharpen and adjust the clarity of your picture.


 * RESIZE** allows you to make the picture a different size. Be careful not to make it too large, or it will pixilate!

All of these options are seen when you open the webpage. You have many other options for photo editing in PicMonkey.

Look at the icons (small pictures) to the very left of the webpage. When you get to the site, the top option is open.

By clicking on the other options, you open even more editing possibilities, such as

Clicking on the **BEAKER** gives you **SPECIAL EFFECTS**!

Clicking on the next picture gives you **TOUCH UP** options, including **RED EYE REMOVER**, which is great for touching up pictures of pets!

Clicking on the **P** lets you add **TEXT**.

Clicking on the picture that looks like a paw lets you add picture **OVERLAYS** on your image.

The next option lets you add a **FRAME** around your picture.

You can also add **TEXTURES** and **THEMES** by clicking on the next two icons.

Practice using these options with your picture.

After you are finished, save the image WITH A NEW NAME to your desktop!

WEEK OF NOVEMBER 5-7:
===On Monday, you are going to work with GeoGebra, a type of free math software!=== ===We are going to look at how to plot points on a Cartesian graph, using GeoGebra.===

===If you are working from home, you should download GeoGebra by going to the following website:===

===This is a link to the web page where you can download GeoGebra.===
 * GeoGebra Download Webpage ||  ||
 * GeoGebra Download Webpage ||  ||

===Click Prime if you want to download the two versions of GeoGebra (regular and Primary grade types) onto your computer.===

===If, for some reason, you can't download GeoGebra, click Applet. === ===This way, you can practice using GeoGebra while you are online that day.=== ===The software will not be loaded onto your computer's hard drive!=== ===(The Applet version will not work while you are offline, or after you turn off your computer.)===


 * || [[image:akrondigitalacademy/12gon.png width="430" height="458" caption="12gon.png"]] ||

===Today, though, we are just going to work as a class to plot points with GeoGebra!===

Plotting points is useful in real life:
===To analyze results of experiments and data (Science and industry)===

To track the progress of a storm, like a hurricane!
===You need to know how to plot points, as it is a subject that shows up on the OAA test!===

===To plot points, you need to look at ORDERED PAIRS OF NUMBERS, that are in the form (x,y)===

So in the ordered pair (4, 7), the x value is 4, and the y value is 7.

In the ordered pair (3, 1), the x value is 3, and the y value is 1.

We are going to go over this more in class, but if you need further help, check out this webpage:
[]

After you feel comfortable plotting points, open GeoGebra. If you have GeoGebra on your computer, you can open it by opening the file below:

NOVEMBER 7:
The assignment for this date was all done in class, and involved class discussion. If you missed this assignment, talk to your instructor about making it up.

=== WEEK OF OCTOBER 29-31: ===

With hurricane storms headed our way, you might want to have something like it to use at home this week!
 * BEGINNING DISCUSSION:** Today, you will look at some technology that is not that old, but is very useful.

===2. How to edit pictures by getting rid of the "red eye."===

You are going to use the program GIMP, which is loaded on your lab computer.

The icon for GIMP (a cartoon figure with a large nose) should be on your desktop.

Click on the icon.

Three different windows should appear. Their names are at the top of the windows.

1. The middle window is called the __GNU IMAGE WINDOW__.
===This is the window where you import (bring in) your picture image to edit.===

2. A second window is called the __TOOLBOX__.
In it, you will find small icons to let you crop, zoom, flip, add text, add color, and other photo editing option.

===3. The third window is called __LAYERS, CHANNELS, PATHS, UNDO, BRUSHES, PATTERNS, GRADIENTS__.=== In this window, you select brushes to paint over an image. It also has the very important EDIT->UNDO command, which lets you undo mistakes!

===Open an image, in the GNU IMAGE window. Go to FILE ->OPEN, and find an image on your computer to use.===

One, called tree. jpg, will be on your desktop. It is also below:

===I used the paintbucket (fill color selection in the TOOLBOX window) to change the "season"!===

===I clicked the paintbucket icon, selected the color red, and then clicked on parts of the tree to change it into the fall picture you see above.===

===Other tools in the TOOLBOX allow you to __flip an image__, //crop// it (make it smaller and keep just one part of the picture), __add text__ over the image, and other exciting options.===

Go to IMAGE -> CROP TO SELECTION
===Remember to go to FILE->UNDO in the third window (LAYERS, CHANNELS, PATHS, UNDO...) to undo a mistake you make!===

For more information:

The link below gives you further information about how to effectively crop a picture: ===[]===

===__REMEMBER TO SAVE YOUR IMAGE INTO YOUR FOLDER ON THE DESKTOP.__=== ===Go to FILE->DESKTOP->OPEN YOUR FOLDER->SAVE AS JPG with your name===

GIMP is a free program. If you want to use this program at home, go to **Software Links (one Wiki page found at the links to the left of this page)**, and select the link for GIMP. Follow the directions online to put it on your home computer!

Want to use GIMP to do a lot of photo editing?

OCTOBER 24:
=== During this class, you worked with more images, especially: ===

===1. How to capture and save screen images that will not save in the usual way, using the keys CTRL and PRNT SCREEN.=== ===2. How to __really__ look at an image to discover different types of lines!===

__**Directions:**__
===First, you learned how to save an image (online or off) from your computer screen. This is important to know, when you can't save something from your computer in the usual way, such as by saving a file, or by printing the screen image.===

===To do this, press the CONTROL (CTRL) key, found at the bottom left of your keyboard, and the PrtSc button, found at the top right side of your keyboard. YOU MUST PRESS THEM BOTH AT THE SAME TIME!===

Doing so copies the image.
===Now, open the __PAINT__ program you used last week. (Microsoft Paint)=== ===Go to START ->ALL PROGRAMS->ACCESSORIES->PAINT.===

===Once the program is open, press CONTROL (CTRL) and V at the same time!=== ===This should copy the image you just saved, and put it into PAINT!===

To save this image, go to FILE->SAVE AS->
===Select DESKTOP->Your folder->and then name the file with your name and prtscr, such as===

__**This exercise is worth 10 points!**__
=== The next part of the lesson was discussed in class. === === If you missed the lesson, look at the images below, to discover the lines inside the images. ===

===Some of these lines will be __parallel__ to each other.=== ===Some of these lines will __intersect__ each other.=== ===Some of the intersecting lines will be __perpendicular__ to each other!===



What kinds of lines do you see in the picture above?



How many different types of lines can you see in this picture? Name them!

On Monday, October 15, you viewed a miniature model of an old piece of technology!
===Your class prepared chili for the cook-off in math class today, using the recipes you found in Language Arts, and using the quantities of ingredients you calculated in math this past week. In technology, you used a digital camera to take still photos and videos of another group preparing their chili! These images will be used by you later in the year to make movies for the Virtual Newspaper, and for your graduation video!===

===Ms. Renker brought in an item that belonged to her grandmother. Her grandmother got this item as a gift in __1890!__===

It is similar to the one pictured below.
===Her grandmother got this item as a gift in __1890!__===

===It is a toy version of an old technology that became useful again!===

We discussed the Y2K "crisis" that faced America on January 1, 2000. How did the possibility of massive, world-wide computer failures lead to the reuse of old technology such as wood stoves?

Find out more by looking at the link below:

After the pictures have been taken, look at these "old" pictures taken with a variety of cameras:
Taken by a professional photographer in 1889. Photo is pasted on cardboard.



An early snapshot, about 1910



Taken around 1925 with the brownie camera shown to the class last week.



Taken around 1935, again with the Brownie camera.



Taken in 1972, with a Polaroid "instant" camera. Who IS that charming teenager???

You either used Microsoft Paint (Found under Start -> All Programs-> Accessories-> Paint, and saved the art to your desktop,
**OR**

drew the images free-hand on paper, and had them scanned in as digital images!
Some of the images you are made with Paint reminded me of the ones pictured below. These paintings were made by Jackson Pollack, a famous artist, whose works sell today for millions of dollars!



This week, you also learned how to make a file folder, rename it, and then save an image from the Internet to that folder!
===On Wednesday, you used this image to make an invitation to the Chili Cook Off on Tuesday, October 16!===

October 1:

 * Follow the steps below. If you don’t know what these terms mean, or need more of an explanation, ask Ms. Renker for help!**

MAKING A FOLDER WITH YOUR NAME ON THE DESKTOP:


 * 1) **Go to the Desktop of your computer (the screen that appears when you turn on the computer.)**
 * 2) **Move the mouse and put the cursor (the blinking light) on an empty part of the screen. Don’t put the cursor over an icon (a picture of a file or folder).**
 * 3) **Click the right mouse button . A new window will appear.**
 * 4) **Move the cursor to select NEW, and then move it again to select FOLDER .**
 * 5) **A new folder will appear. This is just like a paper folder – you can store things (document files, spreadsheets, images, and videos) inside it.**
 * 6) **Name the folder. Right now it just says “New folder.” Give it your name (first and last):**
 * 7) **Click on the beginning of the line where it says “New folder.”**
 * 8) **Type in your name (first and last). Get rid of the words “New Folder.”**
 * 9) **Click with your mouse somewhere else on the desktop. Your folder is named!**

=== NOW, GO ONLINE TO FIND A PICTURE OF A HOT PEPPER TO SAVE IN YOUR FOLDER! ===

=== THIS PICTURE WILL BE USED ON AN INVITATION FOR THE CHILI COOK OFF ! ===


 * 1) **Use Google or another search engine to find a picture you like of a hot pepper. (Type in hot pepper, and then search “images.”**
 * 2) **Select the picture. Avoid pictures with copyright dates or watermarks on them.**
 * 3) **Put the cursor over the image.**
 * 4) **Click the right mouse button. A window will appear.**
 * 5) **Select “save image as”**
 * 6) **A new window will pop up. Along the right, select DESKTOP, and then**
 * 7) ** Select the folder you just made ****. This is very important. If you save the image in the wrong place, you may not be able to find it again!**
 * 8) **Now, under IMAGE TYPE, select ALL FILES. Then click SAVE.**
 * 9) **Your image should be saved in your folder!**

OCTOBER 3:

 * On Wednesday, October 3, you made a flyer for the Chili Cook-Off and Community Open House, to be held at ADA from 6-8:15 PM at your school!**

Directions:
 * Open the document below by clicking on it. It should automatically open in Open Office Writer, a program you are going to use a lot this year!**


 * Then, follow the directions given you by Ms. Renker:**




 * You will insert at least one of the pictures you found online on Monday into your flyer, and then print it out!**


 * Make it a ONE PAGE flyer!**

Take a look at this battery, powered by orange juice! It contains no harmful chemicals! Will it be used in the future, or will it become a "failed invention"?

[]

-
Also, look at this pile of batteries. Just think how many harmful chemicals are in this pile!

===**NOTE TO STUDENTS: For an update on the lesson from September 24 (arsenic, lead, and cadmium in drinking water from computer and cell phone batteries), look at this report that was __just published__ about arsenic __in our food__, from Consumer Reports:**===

[]

WEDNESDAY, SEPTEMBER 26: ** Technology and the Environment, Day 2: **
Today we are going to talk about __throwaway technology__.

Ms. Renker is going to bring in **arrowheads** from her collection. When Native Americans broke an arrowhead in the distant past, did they just throw it away?

**Flint**, used to make arrowheads, was highly prized by Native Americans. Much of it came from the Zanesville area in Southern Ohio.

 * Why did these inventions fail to become popular, even though they were very good inventions? **


 * Old technology like this is probably in landfills across the country!**


 * Does most new technology fail to become popular? What do you think?**
 * Some people predict that __all__ new technology will fail! Look at some silly predictions from the past in the link below!**

 * Assignment for the weekend: Look at the Virtual Newspaper page (the link to it is on the left). **
 * Find your assigned role and department. **
 * If you have any questions/problems with your role or department, be certain to talk to Ms. Renker about it on Monday, October 1! **

September 17-19:
This week, you tried to use some technology from the past. You tried to use several old telephones. **With the oldest ones, you had to dial a phone number with a rotary dial, rather than using push-buttons.**


 * If someone from the past (say 1937) who was used to using a rotary dial phone was given the choice to use a modern cell phone, which one would that person choose?**

Why?

What does this tell you about older technology? Is an old piece of technology really easier to use than one from today?

Does all technology have a learning curve?

September 19:
During this lab, we looked at and discussed changes in telephones over the last 100 years.

First, we looked at a picture of a telephone from the early 1900's. To use this phone, you had to turn a crank, and then ask a local operator to connect you to the other phone line.

Next, we looked at a telephone from 1937-1941, that was made of solid zinc. This model was changed to a plastic model in early 1942. Do you know why the model was made in plastic?

We also looked at other rotary models from the early 1980's. Many students tried to use the rotary dial phones, and decided that they liked today's telephone better.

We also looked at early cordless phones, which had frequenceis that interferred with such things as garage door openers.

This week, you learned about the meaning, or definition, of technology, so that you can answer the questions below in your own words:
What is technology? Does the word just apply to electronic devices ? What would we call technology today? What would people have called technology 50 years ago or 100 years ago? What would people have called technology //4000 years ago//?

On //**Monday**//, you saw an old typewriter from 1903 - that was "high tech" then!

(Image found at [])

On //**Wednesday and on Monday, September 17,**// you chose from //almost a hundred// inventions from the last 4000 years! After picking an invention, you searched online to find out more about the invention, especially:

1. When was it invented? 2. Do we know who invented it? 3. Did this invention change history in any way?

4. Do we still use it today?

Then, you put a card about the invention in its place in time...on a timeline that is on the walls of our tech room!

We started this assignment on Wednesday, September 12, and finished it on Monday, September 17, 2012

** Using Audacity ** Audacity, like Musicshake, lets you build songs by combining different rows, or tracks of music. With Musicshake, you are given the instruments. With Audacity, you have to provide the sounds to be recorded. You can record instruments, singing, or even simply speech using Audacity. **__The instructions below were found at eHow.com:__** []

= How to Record Using Audacity (from eHow.com) = “Audacity is a home recording program that you can use for free on [|your PC] to record multi-track audio pieces. Whether it's music, an Internet "radio show" or a podcast, Audacity is a great place to start with your own experimentation in the world of audio recording.”

Instructions
“Install Audacity on your computer”… The program itself is free and you can install it by downloading it at http://audacity.sourceforge.net/download/ (The school tech lab computers already have Audacity downloaded on them.) “Connect your hardware. A multi-track digital audio recording program is nothing without a microphone to record with. Almost all PC's have a microphone jack, and this will be what you use for your main audio input. A good, uni-directional microphone is best for most purposes, and your local electronics store will most likely have a selection of several.” (The school lab computers do not have microphones attached. Your instructor will bring a microphone to school to use.) … “Once you have the microphone hooked up and set in place, you're ready to record.” “Record a track on Audacity. Open Audacity on your PC. Look at the control panel on the top of the screen. From left to right, **the double backward arrow** button takes you to the beginning of the track, the **forward arrow is** **PLAY**, the **red circle is** **RECORD**, the **double blue lines are** **PAUSE**, the **yellow box is** **STOP**, and the **double forward arrow takes you to the end of the** **track**. Turn the volume down on your speakers, and press **RECORD**. The reason you turn the volume down is because you will hear yourself in delay while you are recording if you don't. Speak or sing into the microphone. When you are done, press **STOP**." “Edit your track on Audacity. If you made a small mistake in your recording on Audacity, there is no need to rerecord the entire track. You can edit anything you want on Audacity. Use the slide bar at the bottom of the screen to take you to the area in the recording that you want to edit. Once you've found the section that you want to edit, highlight that section in the track. Once you have the appropriate section highlighted, press the **DELETE** or backspace button, on your keyboard. The section is gone. If you made a mistake in editing, go to the **EDIT** selection in the toolbar at the top of the screen and press **UNDO**." Add more tracks to your recording. Once you've recorded your first track, you may want to add more layers to your sound. You can record as many additional tracks as you like and line them up however you want. The more you experiment, the more options you'll find you have. **__From another website:__** <span style="display: block; height: 1px; left: -40px; overflow: hidden; position: absolute; top: 19017.5px; width: 1px;">**Basic rules for using Audacity:** <span style="display: block; height: 1px; left: -40px; overflow: hidden; position: absolute; top: 19017.5px; width: 1px;">[]
