Levers of Destruction! Trebuchets, Catapults and Jaws!

This "lesson" was specifically targeting the Nova Engineering Module. As an engineer, I'm a little disappointed they focused solely on levers, so I tried to make it as interesting as possible.  When you're dealing with kids age 6-11, destruction makes things interesting!  We were able to review the three types of lever, while having a snack and shooting paper balls and ping pong balls.


Oil and Water DO Mix!

I started down this path because one of my scouts, H, was extremely interested in chemistry.  H was a 3rd grader Bear Scout who was asking me very insightful questions about how chemicals come together.  I had that in mind when I found a recipe for "Bubble Dough".  Just making Bubble Dough wouldn't cut it as a STEM Den meeting, so I combined it with an intro to polar and non-polar molecules, as well as the Color Changing Milk from Steve Spangler.
