In this activity, learners use simple materials to create giant bubbles.

In this physics activity, learners will explore the concept of buoyancy, especially as it relates to density.

In this activity, learners explore how changes in fluid pressure affect the buoyancy of a Cartesian diver inside a plastic soda bottle.

Learners apply their knowledge from a previous study to identify different liquids--water, corn syrup, and vegetable oil.

In this activity/demo about piezoelectricity, learners discover how some crystals produce electricity when squeezed.

Learners are challenged to discover the relative densities of colored liquids to create a rainbow pattern in a test tube.

In this physics activity, learners attempt to lift a jar full of rice using only a spoon.

In this activity, learners use chemistry to “self-assemble” gummy shapes. Learners discover that self-assembly is a process by which molecules and cells form themselves into functional structures.

Young learners investigate and observe the properties of three liquids -- water, vegetable oil, and corn syrup. They use their senses to collect data and ask and answer questions.

In this activity, learners use cardboard bases and track tubes to make a ball run to explore the properties of mass, force, and motion.

In this activity, learners investigate the speed of chemical reactions with light sticks. Learners discover that reactions can be sped up or slowed down due to temperature changes.

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

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

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 will investigate static electricity as they create waterless snow globes.

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 physics activity, learners recreate Galileo's famous experiment, in which he dropped a heavy weight and a light weight from the top of the Leaning Tower of Pisa to show that both weights fall

In this activity, learners will construct a device to blow bubbles. By adding corn syrup to the bubble solution, we can increase the surface tension of the bubbles--and their size.

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.
