This fun activity uses simple materials such as milk cartons and mirrors to introduce the ideas of optics and visual perception.

In this project, students explore how levers work, by making a puppet with moving limbs.

In this engineering activity (page 5 of PDF), young learners investigate how materials and design contribute to the strength of a structure, particularly walls.
