In this activity, a lightbulb is placed in front of a concave mirror. The actual lightbulb is not visible to the viewer, but the viewer can see the mirror image of the lightbulb formed in space.

In this outdoor biology and math activity, learners estimate the size of a population of organisms too numerous to count.

In this activity, learners explore how various energy sources can be used to cause a turbine to rotate.

In this chemistry challenge, learners identify which plants have the enzyme "catalase" that breaks hydrogen peroxide into water and oxygen.

Learners manipulate opaque, sealed boxes and attempt to determine their interior structures. Each box contains a moving ball and one or more fixed barriers.

In this multi-faceted game (on pages 25-35), learners recreate what happens to creatures in the Brazilian rain forest as they grow from egg to adult—especially those that use fallen, empty Brazil nut

In this outdoor activity, learners search for the warmest and coolest, windiest and calmest, wettest and driest, and brightest and darkest spots in an area.

This activity (on page 2 of the PDF under GEMS Activity) is a full inquiry investigation into technology design and testing.

In this fun optics activity, learners explore principles of light, reflection (mirrors), and perception. Learners work in pairs and sit on opposite sides of a "two-way" mirror.

In this activity about light and reflection, learners discover that what you see is often affected by what you expect to see.

In this outdoor activity/field trip, learners catch and observe water striders to explore their movement and feeding behaviors.

In this set of outdoor games, learners play the role of monkeys that are trying to get enough resources (food, shelter, and space) to survive.

In this activity, learners experience some of the challenges of "tele-operating" a robotic vehicle on another planet when they design and execute a series of commands to guide a human "rover" through

In this activity (page 26 of the PDF), learners make observations, formulate hypotheses and design a controlled experiment, based on the reaction of carbon dioxide with calcium hydroxide.

In this activity, a group of learners work collaboratively to design and construct a paper model showing the evolution of an environment through multiple stages, from prehistory through the modern cit

In this small-group activity, learners assume the roles of pilots, air traffic controllers, and NASA scientists to solve five Air Traffic Control (ATC) problems.

In this activity, learners work in teams to investigate the relationship between mass, acceleration, and force as described in Newton's second law of motion.

In this outdoor activity that can be combined with a hike, learners try to match a "mystery community" by shaking animals out of different trees and shrubs.

From the Weather Watchers featured theme on the CYBERCHASE website. Learners will conduct experiments to discover how air temperature and humidity work together to make condensation, dew, and fog.

In this interactive board game, learners "hire" different types of scientists to help canine character Ruff Ruffman solve unusual problems.
