2. Focus question What defines a wave? Waves Course, 1.2: Spring Waves
Step 1

3. Make compression waves
Teacher master B, Making Spring Waves
Waves Course, 1.2: Spring Waves
Step 4

4. Make compression waves
Teacher master C, Compression Waves
Waves Course, 1.2: Spring Waves

5. Reflection What happened to the masking-tape flag?
Where did the masking-tape flag end up?
When you made a single compression wave, what happened when the wave reached the end of the spring?
Did the entire strength of the wave reflect?
Waves Course, 1.2: Spring Waves
Step 5

6. Make a series of compression waves
Teacher master C, Compression Waves
Waves Course, 1.2: Spring Waves
Step 6

7. Share observations
Was there any reflection in the series of compression waves?

Step 7

8. Wave characteristics All waves have two things in common:
They move in a back-and-forth pattern.
They transfer energy.
Waves Course, 1.2: Spring Waves
Step 8

9. Wave characteristics
What back-and-forth pattern of motion did you see with the series of compression waves?
What energy did the compression wave transfer?
Energy of motion is called kinetic energy.

Step 20

20. Compare wave types
What are the two types of waves that we created and observed in class?
What do those two kinds of waves have in common?
How are the waves different?
