In this chemistry activity, learners use guar gum to make slime. Use this activity to introduce learners to polymers, viscosity, and colloids.

In this activity, learners make plates levitate! Learners build "hovercrafts" using simple materials to explore friction and motion.

In this activity, learners will become an engineer by designing and engineering a miniature parachute.

In this activity, learners explore the properties of paper by constructing and modifying paper airplanes.

This is a highly visual demonstration that illustrates both the effects of density and chemical reactions.

In this chemistry activity, learners make a slimy non-Newtonian fluid called "Gluep." Use this activity to introduce learners to polymers and viscosity.

Build a glider that uses the same physics as a curve ball, for less than a dime.

In this activity, learners try to put together toy bricks—wearing oven mitts on their hands! This activity shows learners how difficult it is to build small things when your tools are too big.

In this activity, learners create a toy that demonstrates the First Law of Thermodynamics or the Law of Conservation of Energy.

In this activity, learners build a LEGO® structure while wearing mittens. This activity shows learners how difficult it is to build small things when your tools are too big.

Learners experiment with a commercially available liquid-crystal coaster. They warm the material with their hands for varying lengths of time and observe the changing colors that result.

In this physics activity (page 6 of the PDF), learners will try to keep a marble in a bottomless cup without touching the marble inside.

In this activity, learners construct a paper glider to experiment with aerodynamic forces.

In this activity, learners concoct some stretchy green goo called Gak. This activity will introduce learners to polymers, chemical reactions, and how scientists invent new materials.

In this physics activity, learners use square blocks to explore how towers fall. Learners attach a piece of string to the side of a block and then construct a tall tower on top of this base block.

In this math activity, learners pretend there is a special store that lets you pay for toys by their height in pennies.

In this math activity, learners pretend there is a special store that lets you pay for toys by their weight in pennies.

Create your own spinning top, and explore color, shapes and spinning. This activity contains instructions for making your spinning top, and tips on how to design and decorate it.

In this activity, learners will experiment with the physics of forces - kinetic energy and friction while making a moving toy woodpecker.

In this activity, learners construct paper airplanes that twist and turn.
