This weekend CVS had all its summer toys on sale for 90% off, so I came away with this haul for $9.
So how will I use all this in my class? I love having a skateboard in class because it’s great to put a dynamics cart in the center of the skateboard, and then secure 2 small ringstands to the front and back of the skateboard, which i use to hold spring scales to the front and back of the cart. Students can then see that the spring scales look exactly the same when the cart is moving forward at constant velocity as it does when it is at rest (which they are starting to realize is just constant velocity).
The planes should make for some fun energy investigations. I think one of the joys of my impending parenthood is going to be getting to visit the toy store much more frequently.
