Our final class focused on different types of waves: water, light and sound. We began by seeing a model of a wave made with gumdrops, skewers, and tape. Then we played with water and sand and built dams with actual sand bags in attempt to prevent erosion. Next we focused on light waves. We saw how light deflected off a CD creates a rainbow, played a game that used refraction to shine a light on a target, and made different shadow figures on the wall. Our final focus was on sound waves. We saw how sound waves travel through the air causing sugar to move on a surface. We used a piece of corrugated pipe to hear how sound waves make a whistle. And we ended by eating loud, crunchy foods and discussing how much fun we had with physics! Pictures are below. Enjoy!
