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 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 explore the concept of how aerospace engineering has impacted sports, specifically exploring the design of golf balls.

In this activity, learners create a gelatinous slime using guar gum powder and borax. Educators can use this simple activity to introduce learners to colloids.

In this activity, learners explore trebuchet design. Teams of learners construct trebuchets from everyday materials.

In this activity, learners explore the design of rubber band powered cars. Learners work in teams of "engineers" to design and build their own rubber band cars out of everyday items.

Learners examine collisions between two skateboards carrying different masses. They learn about conservation of momentum in collisions.

In this physics activity about rotational inertia, learners use a spinning top made out of a bottle cap and a nail to explore how changing the axis of rotation affects how the energy is used.

Learners build at least two different spinners (tops) to investigate how mass distribution, size, and shape affect the length of time the spinner spins.

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

In this chemistry activity, learners transform two ingredients (4% polyvinyl alcohol solution and 4% borax solution) into gooey slime.
