Instructional Ideas

• Create a laboratory handout for pupils to record their data and discoveries

Classroom Considerations

• Expects an understanding of density and buoyancy
• Must create a free account with CK-12 to utilize the interactive

Pros

• Provides questions for pupils to consider after manipulating the simulation
• Includes further examples to reinforce the concept

Cons

• Does not include a lesson guide or outline
