Engage: We will play sound frequency so the kids ask what is going on and we will explain that we are playing a frequency. Then we will turn on the water and let them see what happens.
Explore: We will give them cups with water and they will choose what frequency they want and we will play it so each kid has a different reaction and they will explain to us why that happens.
Explain: We will ask them to take notes about three different frequency and explain why they choose them.
Evaluate: We will ask what is a frequency wave and how does it look like.
