Day 21: Highlights This Week

Today is a quiz day, so I’ll share 2 other things we did this week.

AP Physics C: Students designed their own experiments to determine Young’s Modulus for 3 different types of marshmallows: store-brand jumbo marshmallow, store-brand regular marshmallows, and Jet Puff marshmallows.

College-Prep Physics: We did another speed of sound lab using a Direct Measurement Video called Keeping Time.

Students took data, used Desmos to create a position-time graph for the sound to travel down the line of kids, and fit a trend line to the data to determine the speed of sound.

Not bad!
