In this activity, learners work in groups to design a parachute out of household items that keeps an egg secure when dropped from a certain height.

Learners follow directions to construct a solar oven that really cooks! The solar oven uses aluminum foil to reflect sunlight into a cooking chamber, which is painted black.

In this activity, learners use coverslips to collect organisms from a pond, estuary or marine environment and then examine what they have caught with a microscope.

In this international citizen science activity, learners measure their night sky brightness and submit their observations into an online database.

In this outdoor, ocean-side activity, learners investigate the distribution of organisms in the upper region of the intertidal zone.

Learners place water and part of an antacid tablet in a film canister. The reaction creates a gas reaction that launches the film canister like a rocket.

In this outdoor activity, learners visit the intertidal zone of a rocky coastal site well populated with marine organisms.

In this outdoor activity, learners discover how the environment around a building affects the growth of plants.

In this activity, learners construct hand-held altitude trackers. The device is a sighting tube with a marked water level that permits measurement of the inclination of the tube.

In this outdoor, night-time activity, learners discover how to spot eye-shine (reflection of light from an animal's eyes) by using a flashlight to play a simulation game.

Have you ever heard of a camera without a lens? In this activity, learners create a pinhole camera out of simple materials. They'll see the world in a whole new way: upside down and backwards!

In this activity, learners explore how engineers design devices that can detect the presence of pollutants in the air.

In this activity, learners explore the concept of valve operation and how engineers have adapted valves for use in mechanical heart valve design.

In this engineering design challenge, learners make a bird and then control its flight with attached strings.

In this outdoor mapping activity, learners explore where plants grow and map plant-distribution patterns.

In this activity, learners build a water squirter using a PVC pipe, dowel, and foam. This activity is great for the summer time and introduces learners to forces and water pressure.

In this activity, learners will build rainwater collectors to practice meteorology in their own backyard. Collect and analyze data to determine how much rainfall you get in a set period of time.

In this laboratory exercise, learners will discover how many different plant hosts they can find that are infected by the same genus of a powdery mildew fungus, or how many different genera of powdery

In this activity, learners evaluate the potential performance of air rockets placed inside a wind tunnel.

You may have tried to throw a curveball or a slider, or even a screwball, with an ordinary baseball and found it difficult to do.
