Mighty, Mighty Waves!
1. Draw and label the parts of a wave on your computer lab packet.
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.

You may begin this section only if you have turned in your computer lab packet. You can do these activities in any order you choose.
