In this quick activity (page 2 of PDF), learners will play a game using their observation and listening skills, interpreting clues from each other to deduce their secret animal identity.

In this exploratory activity, learners experiment, observe and determine how various toys change from one form of energy to another.

In this activity, learners conduct a waste audit and use their findings to implement a plan for reducing trash.

In this outdoor game, learners simulate a herd of deer trying to survive in an area called the "home range." Learners explore the concept of "carrying capacity"—what size population of an organism can

In this quick activity, learners take a balance challenge to measure their average balance time. As they collect data, they investigate how practice and repetition improve their balance time.

In this activity, learners use a microscope to examine three different microbes: bacteria, yeast and paramecia. Educator will need to prepare the yeast solution one day before the activity.

In this demonstration, learners can observe a number of small convection cells generated from a mixture of aluminum powder and silicon oil on a hot plate.

In this activity, learners explore surgical instrument design. Teams of learners construct surgical instruments from everyday materials.

In this activity, learners create their own archaeological profiles.

In this activity, learners build their own sound machines and explore the interplay of motion and sound.

In this activity, learners explore sound by constructing tube zithers, stringed instruments from Southeast Asia and the South Pacific.

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.

This activity (located on page 3 of the PDF under GPS: Lava Flow Activity) is a full inquiry investigation into the relationship between an object’s mass and the distance it is thrown by a catapult.

In this activity (page 2 of PDF under GPS: Alligator Habitat Activity), learners will study the adaptations different fish species have developed to survive in their habitats.

In this four-part activity, learners explore how the body works and the chemistry that happens inside living things.

In this activity, learners observe how salinity affects the freezing point of water by making and enjoying ice cream.

In this physics activity, learners build a toy with a figure that spins around like a gymnast on the high bar.

This activity (on page 2 of the PDF under SciGirls Activity: Water Slides) is a full inquiry investigation into speed and motion and takes place at a water park.

In this chemistry challenge, learners work to figure out which of four juices are real, and which is just food coloring and sugar.

In this activity, learners explore the concept of conducting or insulating electricity.
