Who likes magic shows? In the fourth of five lessons, pupils view a scientific magic trick. The ball fits through the ring easily, but then moments later, it won't pass through anymore. What changed? Can we reverse the change? Scholars take their previous knowledge and apply it to a new setting to solve the mystery.

Instructional Ideas

• Challenge students to think of another application for their knowledge of metal expansion

Pros

• The resource is a 5E style lesson plan
• Extension idea is a great real-world applied connection

Cons

• Over simplification of some concepts may cause confusion later
