In this outdoor activity and game, learners explore how animals adapt for survival through coloration, markings and camouflage.

In this optics activity, learners explore how light bends and affects what we see.

In this activity, learners explore polymer structure and their ability to reform around objects by attempting to stab a wooden skewer through a balloon without popping it.

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

Learners use two mirrors to explore how images of images of images can repeat forever.

Make your own speaker with a magnet, wire, and paper cup! If you have a radio with a headphone plug and an old pair of headphones, this is a great tinkering activity.

In this activity, learners explore the structure of plant leaves. Learners find out what happens when they coat either the top or bottom sides of leaves with petroleum jelly.

In this activity, learners experiment with the Stroop Effect by challenging themselves and others to try and read a list of colors as quickly and accurately as possible, with a twist.

In this activity, learners investigate feeding relationships. Learners complete a food web and then make a mobile to represent a food chain.

Learners test their "light-smarts" by playing a game called "Light Quest!" The game board represents an atom and each player represents an electron that has been bumped into the atom's outer unstable
