After reading Seed, Sprout, Pumpkin, Pie by Jill Esbaum and seeing all the different types of pumpkins in the book, I decided that it would be the perfect time to do the simple sink or float experiment. I wanted to do this simple experiment last year with the boys, but I just ran out of time. So I was determined to get it done this year.
Pumpkins of various sizes
Anything else that can get wet
1. Take one object at a time. Let the kids guess whether it will sink or float and then throw it into the water.
2. Record the results on a chart.
The boys had a great time. We discussed the real science behind it for a bit, but in the end they understood it was because most of the pumpkins were hollow.
Have you done the sink or float experiment?
