Density Chemistry Activity

Looking for a way to make the abstract concept of density come alive in a way that students can actually visualize? This is a meaningful, real-world activity which allows students to see changes in density.

Understanding density and recognizing how water becomes less dense as it freezes into ice is a confusing concept for students. This exciting experiment has students discovering for themselves that water spreads out as it freezes.

This is an excellent hands-on experience for all students to observe an important property of water. If you are teaching about density, this is an outstanding yet simple experiment to learn about the density of water and ice and to help explain why ice floats on water.

Included are:

• teacher notes
• a reproducible lab sheet for your students,
• post-experiment teacher notes which explain (with a photo) what students will have observed, along with a kid-friendly explanation, real-world application, and extension activity. The classroom-tested instructions are simple and require only materials that most students already have at home (cup of water, piece of tape, freezer).
• Google Slides^TM version of the reproducible lab worksheets for students to complete in Google Classroom^TM

This is a hands-on lab that is incredibly easy for a teacher to implement. It's great for 5E lesson plans and for teaching the scientific method. Parents enjoy seeing kids doing an actual experiment at home and watching the surprising results.

Your students will love doing this.

This experiment works very well for distance learning and remote learning since the few required materials are things that students already have in their homes.
