In this activity, young learners will describe objects by their properties and sort by color, weight and texture. This activity uses household items and toys for materials.

Learners observe and compare the sizes of three toy “growing” crocodiles made from water-absorbent polymers. One is it its original state, dry, hard, and about 10cm long.

In this physics activity (page 12 of the PDF), learners explore potential and kinetic energy by rolling different sized marbles down an inclined plane.

The goal of this activity is to design, build and test a house or toy for an animal.

In this activity, learners prepare four polymer elastomers and then compare their physical properties, such as texture, color, size, and bounce height.

In this activity, learners investigate visual perception as well as plan and conduct their own experiments.
