James Webb Space Telescope: Investigating How Freezing Affects Materials
In this resource children investigate how the properties of different materials change when they are frozen. The two activities are based on a challenge scientists and engineers had when designing the James Webb Space Telescope: that the space facing side of the telescope needed to withstand very cold temperatures. They think about the temperatures of some familiar things and find out how some materials change with very cold temperatures. They then plan how they might test various materials to see how freezing them affects their properties. In a second lesson they test the effects of freezing on their chosen materials and report their findings.
