In this activity, learners discover that the way a material behaves on the macroscale is affected by its structure on the nanoscale.

In this physical sciences activity, learners explore insulation. Leaners investigate how insulation can be used to slow down the conduction of heat from one side of a wall to the other.

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

In this hands-on activity, learners determine the types of chemical reactions achieved when combining different household products.

In this activity, learners build a simple solar oven out of household materials to melt chocolate and marshmallow between graham crackers--known as s'mores.

In this experiment, learners will conduct chemical and physical tests to identify mystery substances.

In this tasty activity, learners make their own ice cream any day of the year in an exploration of heat and cold. Highlights include freezing and melting and the transition from liquid to solid.

In this physical sciences activity, learners explore how passive solar design increases energy efficiency.

In two separate bags, learners mix water with Epsom salts and detergent.

In this activity, learners mix ingredients in a plastic bag, and then identify three characteristics of a chemical reaction: production of heat, color change, and production of a gas.

In this activity on page 13 of the PDF, use a special plastic card that has been painted with a chemical that changes color when it is in UV light.

In this activity on page 4 of the PDF (Behind the Scenes with Chemistry), learners make some special effects, including snow and breaking glass, with supplies found in the home.

In this activity on page 8 of the PDF (Behind the Scenes with Chemistry), learners make three of Harry Potter's essential school supplies: quills, ink, and color-changing paper.

This activity models the way Landsat satellites use a thermal infrared sensor to measure land surface temperatures.

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