Does it float? Exploring density

Density is a property of matter that requires abstract understanding from your students. This lesson plan is a hands-on lab for exploring the concepts of mass, volume, density, and their relationship. This lab achieves several 8th grade science objectives and incorporates mathematical objectives as well. The lab can easily be used as an introductory lab for the year, thus covering not only the content objectives, but also procedures for completing labs throughout the course of the year.
