In this laboratory activity, learners use a simple procedure to bait oomycetes from water and/ or soil and then examine these fungus-like organisms with the microscope to see how they look.

Create an illusion where it appears that your hand has a hole in it. You'll see the results from when one eye gets conflicting information.

Learners use beach profile data from a local beach or online data from Ocean City, Maryland to investigate coastal erosion and sediment transport.

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 simulate nature's water filtration system by devising a system that will filter out both visible and invisible pollutants from water.

In this activity, learners explore the behavior of cold-blooded animals. Learners discover what happens when they change a fly's temperature.

In this creativity-based activity, learners imagine what the Earth will look like in the near and distant future, then design their own future habitat and creatures that may live there.

In this activity, learners explore the invisible infrared radiation from an electric heater.

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.

After learning that some of the chemicals we add to food crops may have harmful consequences on our health and the health of the environment, learners will create a pocket-sized card with their favori

In this activity, learners explore how to stay fit the fun way. Learners participate in three physical activities.

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.

This warm weather activity introduces learners to the impact trees have on blocking the sun's heat and reducing temperature on the Earth's surface.

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 the human influences on the carbon cycle and examine how fossil fuels release carbon.

In this simulation, learners model two elephant seal populations and how they change over time. Learners start with cards representing a variety of seals.

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