In this environmental science activity, learners research what is essential for plant life and the necessary components of soil to support plants.

In this activity, learners explore how salt water freezes in comparison to fresh water.

In this activity, learners investigate the speed of chemical reactions with light sticks. Learners discover that reactions can be sped up or slowed down due to temperature changes.

In this activity (pages 3-4), learners investigate the properties of smart materials, which are materials that respond to things that happen around them.

Learners observe working lava lamps to understand how they work (included in PDF link).

Learners investigate one factor affecting reaction rates: temperature. In a darkened room, two identical lightsticks are placed in water -- one in hot water and one in cold water.

In this activity learners compare the bounciness of warm and cold racquetballs to see if temperature makes a difference in how well they bounce.

Learners investigate signs of a chemical reaction when they mix vinegar and baking soda. In addition to a gas being produced, learners also notice the temperature decreases.

This lesson focuses on two simple activities that younger learners can do to gain an appreciation of nanotechnology. First, learners measure their hands in nanometers.

In this activity on page 7 of the PDF, learners investigate the solubility of gas in water at different temperatures. This experiment will help learners determine if temperature affects solubility.

In this chemistry meets cooking activity, learners make carbonated, vanilla ice cream using dry ice and denatured ethanol, which are both inexpensive and accessible.

In this activity (pages 13-14), learners investigate the properties of smart materials, which are materials that respond to things that happen around them.

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 activity, sodium acetate hand warmers are used to introduce learners to supersaturated solutions, crystallization, and exothermic reactions.

In this online activity, learners experience the thrill of pickle making, and explore how a cucumber becomes a pickle.

In this activity (pages 5-7), learners investigate the properties of smart materials, which are materials that respond to things that happen around them.

In this activity, learners examine the parts of a thermometer. After placing a thermometer in hot and cold water, learners look at molecular model animations of the liquid in a thermometer.

Learners design their own experiment to compare how well cocoa mix dissolves in cold and hot water. They will see that cocoa mix dissolves much better in hot water. Adult supervision recommended.

"What's in the Water" lets participants use tools to solve the mystery- what chemicals and compounds are in a sample of water?

In this activity, learners explore how engineers have met the challenge of keeping foods, liquids, and other items cool.
