This open-ended art project allows learners to create their own colorful ice sculpture by using rock salt and food coloring on a solid block of ice.

In this activity, learners use cheap, thin plastic garbage bags to quickly build a solar hot air balloon. In doing so, learners will explore why hot air rises.

In this up-cycling activity, learners recycle plastic bags and repurpose them into useful wallets.

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.

If you have access to a copper metal tube, this activity does a great job demonstrating what happens to matter when it's heated or cooled. This activity requires some lab equipment.

Learners set up three different bowls, each with a different mass of oatmeal. Learners monitor the temperature of the oatmeal and find that larger masses take longer to cool.

In this demonstration, learners explore the thermal properties of rubber. Learners investigate whether a rubber band contracts or expands when heated.

In this activity, learners investigate the effect of heat on a reaction.

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.

In this chemistry activity, learners perform three chemical reactions in a sealed zip-top bag. Learners will record their observations and classify the changes as chemical or physical.

In this demonstration/experiment, learners discover that different colors and materials (metals, fabrics, paints) radiate different amounts of energy and therefore, cool at different rates.

In this two-part activity, learners use everyday materials to visualize one mole of gas or 22.4 liters of gas. The first activity involves sublimating dry ice in large garbage bag.

In this activity, learners explore atoms as the smallest building blocks of matter. With adult help, learners start by dividing play dough in half, over and over again.

This demonstration/activity helps learners understand why higher elevations are not always warm simply because "hot air rises." Learners use a tire pump to increase the pressure and temperature inside

In this activity, learners simulate the energy transfer between the earth and space by using the light from a desk lamp desk lamp with an incandescent bulb and a stack of glass plates.

In this chemistry activity, learners use the lowered freezing point of water to chill another mixture (ice cream) to the solid state.

In this activity, learners will experiment with catalysts to create an at-home version of elephant toothpaste.

In this activity, learners discover that our hands are not reliable thermometers.
