Three of our children participated when we were assigend to Robins Air Foce Base in Georgia. They absolutely loved it. It was a week long session on math and science primarily.
They did build a rocket kit. The session was split into two days so the work from day one could dry before finishing on day two. The last event of the week all the parents attended to see what the kids had created and watch each child launch their own rocket.
Twelve years later they still talk about the science projects they worked on during the week.
And I still have their rockets as part of our collection.
