In this activity, learners create a "mini sky" in a glass of water in a dark room.

This activity generates learner excitement about light through the creation of a room-sized rainbow.

In this activity, learners make a model of the hot water of a deep sea vent in the cold water of the ocean to learn about one of the ocean's most amazing and bizarre underwater habitats.

In this health activity (on page 3 of the PDF), learners will learn about the body‘s defenses against invasion from tiny particles.

In this demonstration, learners observe vinegar and baking soda reacting to form carbon dioxide (CO2) gas.

In this demonstration, learners compare and contrast regular water ice to dry ice (frozen carbon dioxide). Both samples are placed in a solution of acid-base indicator.

In this activity, learners dissect a piece of pizza to learn about nutrients important for health.

In this activity, learners try to blow up a balloon hanging inside of an empty bottle.

Learners use Benedict’s solution and heat to test for the presence of simple sugars in glucose, sucrose, starch, and starch combined with amylase.

In this activity, learners make their own heat waves in an aquarium.

In this activity, learners experiment with their voices and noisemakers to understand the connections between vibrations and the sounds created by those vibrations.

In this activity/demo, learners investigate biobarcodes, a nanomedical technology that allows for massively parallel testing that can assist with disease diagnosis.

In this activity, learners make self-assembled polymer spheres.

In this group activity, learners will explore the characteristics, functions and uniqueness of the mangrove tree.

In this activity, learners act as water molecules and travel through parts of the water cycle to discover that it is more complex than just water moving from the ground to the atmosphere.

In this activity, learners consider the water features they might enjoy at a community park--a pond, brook, water playground (or "sprayground"), or pool--and what happens to the water over time.

Working in groups, learners model the continuous destruction and creation of ozone (O3) molecules, which occur in the ozone layer.

In this activity, use standard playing cards to introduce learners to cellular interactions such as cell to cell recognition and signal and receptor specificity.

Learners observe and discuss a vacuum cleaner as a model of a baghouse, a device used in cleaning industrial air pollution.

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
