Floating Marshmallows and Paper Test

We used our knowledge of density to try making marshmallows sink in water instead of floating.

This student took two tries to get one to sink. 

The students tried different things: breaking the marshmallow apart, flattening it, and squishing it into a small ball. 

Today our other quest was to find out which foods had the most fat in them.  Each child selected a food and then mashed it between two sheets of paper.

The foods that turned the paper translucent had the most fat in them.  This is the butter test. 

We were not surprised that peanut butter had a lot of fat. 

Most of the students predicted that the sugar had a lot of fat but the paper test showed us that it didn't.

We also had time to listen to an article about edible insects.  Even after learning that more than 2 billion people in the world eat insects on a regular basis, most said that they would not try them.  Google edible insects to view some interesting snack ideas. :-)
