In this activity, learners examine fingerprints. Learners leave a hidden print on a surface and then make their own print detecting powder from graphite (found in pencils).

In this demonstration, learners discover that nanoparticles behave differently, in part because they have a high surface area to volume ratio.

In this activity, learners cut out a fish and then "paint" it using universal indicator and acids and bases.

In this activity, learners explore how water behaves differently when it comes in contact with "nano sand" and regular sand.

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

In this activity (on pages 18-29) learners explore the impact of the March 24, 1989 oil spill in Alaska caused by the Exxon Valdez tanker.

In this simple activity, learners see the production of a gas, which visibly fills up a balloon placed over the neck of a bottle.

Learners smell balloons filled with different scents to guess what's inside. From this, they infer the presence and motion of scented molecules.

Learners investigate how temperature affects the rate of chemical reactions by observing how steel wool reacts with various types of Kool-Aid solutions at different temperatures.

The "Rocket Reactions" activity is an exciting way to learn about how materials interact, behave, and change.

In this activity on page 10 of the PDF, learners detect the amount of energy that can flow through a sodium chloride electrolyte solution with a light sensor.

In this online interactive simulation, learners will add different salts to water and then watch the salts dissolve and achieve a dynamic equilibrium with solid precipitate.

Learners use a simple process to extract DNA from strawberries.

In this playful, goopy activity, learners mix two liquids to create a solid (that sometimes acts like a liquid ), using basic household materials such as borax and glue.

In this activity, learners investigate the process of osmosis by adding salt to a sealed bag of raw carrots and comparing it to a control.

In this activity, learners mix milk, vinegar, baking soda, and water to create sticky glue. Use this activity to explain how engineers develop and evaluate new materials and products.

In this activity on page 15 of the PDF, learners measure the amount of bubbles that they make using a detergent.

In this activity, learners discover how a super-absorbing material can be used to move a straw.

In this activity (on pages 34-39), learners make a fairly detailed model of DNA using licorice and gumdrops.

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