Mighty, Mighty Waves!

1. Draw and label the parts of a wave on your computer lab packet.

2. Open the "Waves on a String" PhET simulation. Click Run Now.

3. Spend 5 minutes experimenting with the different features of "Waves on a String."

4. Now that you've gotten familiar with everything, turn your paper over and choose either Amplitude -OR- Frequency as your independent variable.

5. Write your focus question:

• How does the amplitude affect the ____________________. (you choose what you investigate).
• How dies the wavelength affect the ____________________. (you choose what you investigate).

6. Record your independent variable (you've already done this) and dependent variable.

7. Make your prediction

• If the amplitude increases, then the _____________ will ________________.
• If the wavelength increase, then the _____________ will ________________.

8. Make sure you've set all the tools according to the independt variable you choose (tool settings are on the back of the first page). Now experiment with your independent variable and record observations.

9. Now you're ready to start collecting data!

(a.) Set your first independent variable (the amplitude or the frequency) - write it down in your data table

(b.) Now run your simulation three times and measure and record the WAVELENGTH in your data table each time.

(c.) Change either the amplitude or the frequency and run the simulation three more times recording your wavelength data as you go along.

(d.)Continue changing your independent variable and recording the wavelengths until your data table is complete.

10. Using the data you collected, make a LINE graph.

11. Turn in your packet.

Computer Lab 1/22/10

1. Write a short constructed response in Microsoft Word. You must choose one of the two SCR writing prompts below.

A. Explain how blankets work. In your short constructed response you must include:

• A topic sentence.
• Explain how blankets work using your science vocabulary words (See word bank to the left).
• What type(s) of thermal energy do blankets use?
• Which blanket would keep you warmer? - Explain why using your science vocab words (see word bank to the left).
• Make sure your name is on your paper.
• Print out a copy and give it to Ms. O'Connor

B. Explain how the kinetic theory is related to thermal energy. In your short constructed response you must include:

• A topic sentence.
• Explain how molecules' movement changes as temperature changes.
• What is the connection between convection and the kinetic theory? (See word bank to the left)
• Give an example of how an object changes as heat is applied to it.
• Make sure your name is on your paper.
• Print out a copy and give it to Ms. O'Connor

2. Play Who Wants To Be A Energy Millionaire?
