This three-part lab helps learners understand the essential principles governing diffusion and osmosis.

In this activity, learners explore the function and engineering of dams and how dams have many uses and solve many problems in the world.

In this activity, learners will explore light and rainbows with this easy setup! Learners will only need a cup of water, some paper and a flashlight.

Build a hydrometer (measures the density of a liquid) using a pipet or eyedropper.

In this outdoor activity, learners race small boats, made of cork, balsa wood, popsicle sticks etc., to investigate the rate and direction of currents in a stream or creek.

In this chemistry challenge, learners discover that many chemical reactions involve heat loss or gain.

In this activity, learners observe how salinity affects the freezing point of water by making and enjoying ice cream.

Learners create a small explosion by collecting hydrogen and oxygen gas together and squeezing them into a flame.

Learners follow directions to construct a water-powered electrical generator using a turbine made from plastic spoons.

In this activity, learners explore and compare the buoyant properties of materials found in nature and in human-made materials.

In this activity, learners will explore surface tension, what it is, and how we can change it.

Learners place water and part of an antacid tablet in a film canister. The reaction creates a gas reaction that launches the film canister like a rocket.

In this activity, learners will explore how density is affected by temperature and how that can create currents.

In this activity, learners will make homemade jello that glows under a blacklight. They will learn about quinine, an ingredient in tonic water that is fluorescent.

In this activity, learners will make predictions and experiment with different objects to see if they sink or float.

This hands-on experiment will provide learners with an understanding of the issues that surround environmental cleanup.

In this activity, learners will explore basic information about thermodynamics by experimenting with ice. Learners will compare ice melting rates on metal pans or plastic cutting boards.

In this activity, learners will explore saturated solutions and discover how crystals form.

In this activity learners will explore the concepts of density and matter in their quest to answer one simple question-will it sink or will it float?

In this activity, learners create secret messages using a candle. Learners discover that watercolor paint is attracted to some materials, like paper fibers, but not others, like oil.
