In this activity, learners make a paper model of a polymer, then make Silly Putty, an actual polymer.

In this activity, learners make pykrete by freezing a mixture of water and a material like cotton wool, grass, hair, shredded paper, wood chips, or sawdust.

In this activity, learners use pop-beads to understand the characteristics and properties of polymer chains.

Learners carefully pour vegetable oil, water, and corn syrup in any order into a cup and discover that regardless of the order they are poured, the liquids arrange themselves in layers the same way.

In this activity, learners discover if carbon dioxide has an effect on temperature.

In this demonstration, learners watch as a device drops a ball into a cup without touching the ball or cup, even though the ball and cup are virtually side-by-side.

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

In this indoor or outdoor water activity, learners pour water from small cups to large cups and containers. In doing so, they discover water takes the shape of its container.

This series of chemistry stations is designed to accompany the PBS documentary about African-American chemist "Percy Julian: Forgotten Genius." Each of the six stations features either a chemical or p

In this activity, learners can create five-layer density columns by employing one of three (or all) methods.

In this activity, learners will experiment with density and chemical reactions to create a flurry activity.

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 activity, learners explore the human influences on the carbon cycle and examine how fossil fuels release carbon.

In this classic hands-on activity, learners estimate the length of a molecule by floating a fatty acid (oleic acid) on water.

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.

Working in small teams, learners try to build a satellite that can float for at least five seconds in the marked area of a vertical wind tube.

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.

In this activity, learners explore how pens have been engineered and re-engineered over time. Learners work as a team to develop a working pen out of everyday items.

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