The Concept: Students will become familiar with the proper way to use pipettes or droppers for experiments involving liquids. Teaching children to squeeze and release the dropper is great for improving small-motor muscles. The pipette can also be used to discuss the concept of air: When the pipette is squeezed, the air is pushed out. When it is let go, the air outside the dropper pushes the water inside the dropper.

Pouring and More: Funnels and Test Tubes
Posted onThe Concept: This activity introduces a funnel as a tool scientists and other individuals use to prevent spills. Once children know how to use a funnel, you can add it to the sand-and-water table. It also introduces test tubes as tools for holding liquids. Students will explore the proper use of test tubes and the use of funnels to make pouring easier.
