Averages

This collection of STEM resources is based around averages.  Resources are listed in order of stage.

Avalanche!

Stage: 2 and 3 Challenge Level: Challenge Level:1

Investigate how avalanches occur and how they can be controlled

Reaction Timer

Stage: 3 Challenge Level: Challenge Level:1

This problem offers you two ways to test reactions - use them to investigate your ideas about speeds of reaction.

Terrariums

Stage: 3 Challenge Level: Challenge Level:1

Build a mini eco-system, and collect and interpret data on how well the plants grow under different conditions.
