Better Lessons: Orange You Glad That You Are Learning about Density?

Students will explore the concept of object density by completing a simple investigation. Students are surprised by the results of this hands-on investigation in which they test the buoyancy of an orange with and without a peel. Getting an unexpected result can challenge our students’ thinking, opening up new ideas and drawing new conclusions. This lesson was designed for kindergarten, but easily could be adapted for grades 1-2.
