Encourage tinkering with ideas, relationships, connections. Set up situations where students have to find information not readily available in school texts. Provide opportunity for students to design open-ended explorations of the concept. Provide multiple options so students can plan a unique "proof" of learning.
Student activities: drawings, two other concepts, or two personal solid objects.
Objective: To give students the opportunity to personalize learning.
Activity: Students are asked to choose one of the following: 1. Draw a picture showing two objects of different density. Make sure the picture is detailed enough to show why the densities are different. 2. Find out two other concepts (in science or otherwise) that can be expressed as ratios. Report on those equations. 3. Determine the density of two solid objects that you own. Explain how you determine the density.
