In this activity, learners combine two substances (plaster of Paris and water) to make a cast of an object's imprint in clay.

In this optics activity, learners explore why the sky is blue and the sunset is red, using a simple setup comprising a transparent plastic box, water, and powdered milk.

In this demonstration, learners compare the relative sizes and masses of scale models of the planets as represented by fruits and other foods.

Bones are stiff, which helps us lift heavy things and walk around, but they are also somewhat flexible, which lets them bend slightly.

In this experiment, learners separate different types of molecules in marker inks (using a technique called "thin layer chromatography").

In this chemistry activity, learners use thin layer chromatography to determine the molecular composition of different markers.

Learners build a filter from old soda bottles and dirt. They create polluted water, and pour it through their filter to clean it.
