LEGO Sink or Float

This program served dual purposes!!!  

Add a little dish soap to some water, challenge the kids to build something out of LEGO that will float, and wallah! It was one of THE BEST LEGO programs I've ever had. Kids were engaged, they were talking between themselves and working together to build better floating structures. I was able to throw in words like density, and surface tension. The kids loved it and it was amazing to watch. 

Prep time for this program about 5 minutes! I had to kick them out after an hour and a half. 

Next time I will bring some of my old beach towels so we won't have to use so many paper towels.

LEGOs were cleaned in the process of creating floating structures.
