This is not your regular density lab. Students determine and compare the density of a whole candy bar to the density of a half candy bar after they have predicted the outcome.
Even my honors chemistry students have trouble realizing this concept and will predict that the half candy bar will have less density than the whole candy bar!
The purpose of this lab is to show students that density is an intensive property– the amount of the sample does not affect the value.
STUDENTS LOVE THIS LAB!
