In this activity, young learners will explore light and darkness through flashlight play.

In this activity, learners create a simple “top” from a CD, marble and bottle cap, and use it as a spinning platform for a variety of illusion-generating patterns.

In this activity, learners explore the different salinities of various sources of water by taste-testing.

In this activity, learners discover how bats use echolocation to get information about objects in their environment. During the activity, one learner whispers into a tube.

In this activity, learners create three-dimensional shapes by making some origami models of simple boxes and containers.

In this engineering design challenge, learners animate a facial expression and make a machine (zoetrope) that plays the animation back.

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

This activity (on page 2) explores how sensing is part of robotics. Learners try tying their shoes with different constraints.

Learners conduct a "blind" taste-test of several types of enhanced or fitness water drinking water that has commercially added substances like vitamins, sugars, or herbs.

In this activity, learners create a cylindrical mirror to see themselves as others see them.

This is a quick activity (on page 2 of the PDF under Butterfly Wings Activity) that illustrates how nanoscale structures, so small they're practically invisible, can produce visible/colorful effects.

In this optics activity, learners discover basic lens-making techniques by using a tennis ball to make a lens out of ice.

In this activity about light and refraction, learners make a lens and magnifying glass by filling a bowl with water.

In this activity, learners create a xylophone by filling glasses with different amounts of water and tapping them with a metal spoon.

In this activity, learners explore why the sky is blue. Learners model the scattering of light by the atmosphere, which creates the blue sky and red sunset, using a flashlight and clear glue sticks.

In this group activity, learners see and hear the speed of sound. A learner designated the "gonger" hits a gong, once every second, as the rest of the group watches and listens from a distance.

In this activity, learners use plastic tubing and a funnel to listen to their heart. Learners also discover that if they run around, their heart pumps harder and faster, making it easier to hear.

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 construct a three-dimensional ambiguous cube to explore visual illusions and how our brains interpret or misinterpret information.

Learners discover how important their thumbs are by attempting various tasks without them. After tying up their thumbs, learners attempt to legibly write their names or play catch with a tennis ball.
