This is a set of 16 task cards with questions covering:
-Converting between frequency and period
-The relationship between frequency, wavelength, and speed
-Wave speed on a stretched string
-Superposition of waves
-The Doppler Effect
I've included an answer key and an editable student handout for students to show their work and record their solutions.
Depending on the group of kids I'm teaching, I either print the cards with the solutions on the back so they can check their work right away, or I print the cards without the solutions, and we check the answers together as a class.
**Tip: The questions are roughly in order from easiest to hardest, so if you have students who struggle it might be best to start them of with card A and ask them to work in order!
