The purpose of this assessment probe is to elicit students’ ideas about density. The task is designed to find out if students think a solid object will float differently if it has holes poked all the way through it or if they confuse it with mixed density.

The probe tests students knowledge of density by asking if an object will still float if it has holes is in it. I use apple slices in my classroom for students to be able to test. We use straws to poke holes.
