How far can you see out of the corner of your eye? Grab a partner and find out from the Exploratorium Science Snack.

Use this hands-on activity to demonstrate infrared and thermal radiation.

In this activity, learners will explore trends in Canada goose populations using real data from the National Audubon Society's Christmas Bird Count.

In this outdoor activity linking human health to the environment, learners use their pulse rates as a measure of the effort expended in walking on different slopes.

In this group activity, learners act out key stages of the "ocean carbon cycle" (also known as the "carbonate buffer system") through motions, rearranging blocks and team tasks.

Can you think of ways to collect and dispose of spilled oil without causing further harm to the environment?

This activity guide features three related explorations to help learners ages 3-6 investigate shadows via the following science concepts: A shadow is made when an object blocks the light; you can chan

In this quick and easy activity and/or demonstration, learners use two empty 2-liter bottles and hot tap water to illustrate the effect of heat on pressure.

In this activity, learners observe live fish in tanks to consider how their body structures are related to their behaviors and habitats.

In this activity, learners (at least three) work together to explore the effects of atmospheric pressure.

In this robotics activity, learners find ways to express emotions and feelings using only body movements, not facial expressions.

In this optics activity, learners explore color by examining color dots through colored water and the light of a flashlight.

Are there boxes, is this an illusion, or is this real life Q-bert? Illusions are always fun to build especially when you can build them.
