Stop the Stretching
Stretch your teaching repertoire with an experiment on the elongation (stretching) and failure (break) of several materials. The point of the experiment is to design a composite material for chair webbing.

Exploring the Forces of Tension
Let the resource stretch the minds of your young scientists with a instructional activity about tensile strength and stiffness of materials. Groups consider how easily materials stretch and relate this property to engineering design.

Bounce Back - The Long and Short of It
Upper elementary scientists test basketballs with differing amounts of air to find if inflation affects bounce height. The instructional activity introduction poses the question of whether or not the composition of a ball determines...
