Day 32: EM Spectrum

Friday, September 26 2014


Physics kids watching a short clip about the mantis shrimp. Today, I started our unit of study on Light & Optics with a lively introduction to the EM spectrum, visible light, and a fun tangent into colorblindness and color perception. Because our physical science course in 8th grade focuses on mechanics, these kids have never learned about visible light. I always have so much fun on this day!

Best question? “I can’t even imagine a color I’ve never seen before. What do these colors look like to the mantis shrimp?”

We wrapped up with a few calculations between wavelength and frequency for EM waves before kids dove into their classwork. My proudest moment on the classwork is below:
