Today was our last science enrichment class. Our topic was “propulsion” and we talked about how rockets work. Our experiments were a lot of fun.

First, balloon races where we show how the air (the propellant) pushes the balloon:

Then we couldn’t resist blowing up a few bottles of Diet Coke by dropping Mentos into them:

And finally each of the kids got to launch an air rocket that uses pressurized air to shoot about fifty feet into the air:

We had a lot of fun teaching the kids and getting them excited about science. Maybe one of these second-graders will end up being a world-famous biologist or astrophysicist!
