Spring 2017 MIT Spark, Columbia Splash

This is very belated, but I taught two classes at MIT Spark and Columbia Splash this spring. Spark is aimed at middle school students, and Columbia Splash is for students in grades 8-12. The two classes I taught were both one hour long, one about weather data (in particular, using and interpreting skew T-log p plots) and one about ballet in the Soviet Union. Any feedback is welcome!
