Lesson 20
Science of Density
Science Standards Addressed:
- Describe the characteristics of the 3 states of matter (solid, liquid, gas).
- Describe how matter is ordered in solids, liquids, and gases and the changes that occur to them when heated.
Plus we snuck in some speaking and listening standards like asking questions, expressing ideas, following multi-step directions, and participating in discussions.
As the children arrived, to go along with our density is like kids packed into a school bus analogy, we played the songs Don’t Stand So Close to Me, by the Police; The Wheels on the Bus, and My Name is Cheech the School Bus Driver, by Cheech Marin.
This is what we put out in the snack area. It was pretty much one of everything from the produce section of the grocery store plus diet and regular sodas. We pretended this was a normal snack. We let the kids be confused for a bit and then brought out a normal snack.

All of this stuff was for some fun experiments on density (below). |
