Learners observe a sealed test tube containing a small amount of solid stearic acid.

This creative lesson plan provides a visual way for learners to gain knowledge about the finite amount of fresh water on Earth and encourages the discussion of the various ways to conserve this resour

In this activity, learners explore inertia as they attempt to whip a strip of paper out from under two coins dangling on the rim of a water glass.

In this activity about light and reflection, learners use a special device called a Mirage Maker™ to create an illusion.

In this optics activity, demonstrate diffraction using a candle or a small bright flashlight bulb and a slide made with two pencils.

This demonstration activity models how Venus appears from Earth.

In this demonstration about momentum, use physics to distinguish between a hard-boiled egg and a raw egg without cracking them open.

In this activity, educators can demonstrate how the nanoscale arrangement of atoms dramatically impacts a material’s macroscale behavior.

In this activity, learners explore the concept of permeability to better understand why amphibians are extremely sensitive to pollution.

In this chemistry demonstration, learners investigate the factors that increase the rate of dissolution for a solid.

In this activity, learners explore the forces at work in water. Learners experiment to find out what happens to pepper in water when they touch it with bar soap and liquid detergent.

In this activity, learners will discover what it takes to be a frog. By dressing up like one, learners can visualize how each part of the frog plays an important role in surviving its habitat.

In this chemistry demonstration, learners observe a chemical reaction that produces a colorful effect.

In this activity, learners explore deoxyribonucleic acid (DNA), a nanoscale structure that occurs in nature.

In this physics demonstration, learners are challenged to break a raw egg just by squeezing it. Learners will be shocked by their inability to complete the deceivingly simple challenge.

Learners observe and discuss a simple model of a wet scrubber, a device for cleaning industrial air pollution.

In this activity, high voltage is applied across a pickle to emit a yellow glow. This activity should only be conducted by skilled adults and is best suited as a demonstration.

In this activity, learners are introduced to robotic submarines called gliders. Learners make “gliders” from plastic syringes and compare these to Cartesian bottles and plastic bubbles.

In this activity, learners investigate how increased carbon dioxide (CO2) emissions from the burning of fossil fuels is changing the acidity (pH) of the ocean and affecting coral reefs and other marin

This fun and simple hands-on astronomy activity lets learners build a scale model of the universe with little more than adding machine tape.
