In this outdoor activity/field trip, learners conduct experiments to explore where dragonflies and damselflies perch or rest, and how the flies change behavior in reaction to other flies or fly decoys

In this activity about global climate change, learners will conduct an experiment and collect data to compare the amount of carbon dioxide (CO2) in four different sources of gases.

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

In this multi-station lab, learners conduct a series of experiments to explore the processes and effects of weathering and erosion.

In this activity, learners investigate how increased carbon dioxide (CO2) emissions from the burning of fossil fuels is changing the acidity (pH) of the ocean and affecting coral reefs and other marin

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.

This lesson focuses on molecular motion in gases. Learners compare the mass of a basketball when it is deflated and after it has been inflated.

In this physics activity, learners construct a small-scale version of a classic carnival game.

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

In this optics/mathematics activity, learners use two hinged mirrors to create a kaleidoscope that shows multiple images of an object.

In this earth science activity, learners conduct a series of short experiments to explore how rocks change.

Learners explore water adhesion and learn about why water molecules are more strongly attracted to some substances than others.

In this activity, learners build an electromagnet using a nail, a cork, a battery, and electrical wire. Use this activity to demonstrate how electric currents produce magnet fields.

In this outdoor activity/game, learners use thermometers to simulate how lizards survive in habitats with extreme temperatures.

In this outdoor, mystery-solving activity, learners work like detectives, gathering evidence to identify the culprits that are attacking plants.

In this sunny day experiment, learners measure and compare how quickly light and dark colored materials absorb heat.

In this activity, learners explore sound by constructing their very own instruments using PVC pipes, soda bottles, and a straw.

In this activity about human anatomy (page 20 of PDF), learners investigate the structure of muscles by comparing yarn and cooked meat.

In this food science activity, learners conduct an experiment that demonstrates the importance of light to plants.

This activity (on page 3 of the PDF under GPS: Body Electricity Activity) is a full inquiry investigation into conductivity.
