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

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

In this activity, learners will explore globes of frozen water to learn how to ask and then answer 'investigable' questions. The activity web page includes a short video demonstration.

In this activity (pages 17-31), learners are introduced to techniques that are used to determine the structures of solid materials.

Learners observe two joined glass tubes containing a conductive salt solution. Electrodes are passing an electric current through the water.

In this activity (pages 7-16), learners model various crystal structures with LEGOs. This activity also contains additional links that explain how to create other crystal structures.

This quick demonstration (on page 11 of PDF) allows learners to understand why scientists think water ice could remain frozen in always-dark craters at the poles of the Moon.

In this activity, learners will use string and salt to lift an ice cube out of a glass of water. Salt depresses the freezing point of water, allowing it to melt around the string and refreeze.

Yes, you can weigh your car by figuring out your wheel's tire pressure combined with the "tire's footprint." You'll need someone with a car, driver's license, and safety in mind.

In this chemistry activity, learners fill two test tubes with a solution of "artificial stomach fluid," consisting of hydrochloric acid in the same concentration as in human stomachs, some soap to cre

This activity uses LEGO® bricks to represent atoms bonding into molecules and crystals. The lesson plan is for a 2.5 hour workshop (or four 45-minute classes).

In this activity, learners use ABS pipe and an air leaf blower to make a strong shooting machine.

In this demonstration about momentum, use physics to distinguish between a hard-boiled egg and a raw egg without cracking them open.

In this activity, educators can demonstrate how the nanoscale arrangement of atoms dramatically impacts a material’s macroscale behavior.

Visitors observe a bottle with a balloon attached around the mouth. The bottle contains a solution of yeast, sugar, and water.

In this activity, learners find out why some mineral sunblock rubs in clear. Learners compare nano and non-nano sunblocks and discover how particle size affects visibility.

In this activity, learners discover that a material can act differently when it's nanometer-sized.

In this activity, learners are challenged to design a planktonic organism that will neither float like a cork nor sink like a stone.

In this activity, learners will explore the physics of liquids and gas by playing with both! Learners of any age use their own breath to move drops of water across a smooth wax paper surface.
