In this chemistry activity, learners use common chemicals to examine reactions that occur between two aqueous solutions.

In this math lesson, learners determine and compare the rate of descent of various learner-constructed parachutes. Learners construct parachutes that will have maximum hang times.

In this plant science activity, learners conduct four experiments to observe how plants respond to sunlight and gravity.

In this activity about sleep rhythms (on page 21 of the PDF), learners will collect data about their own sleep cycles and use a fraction wheel to examine their data.

In this activity, learners build mini-basketball courts using cardboard and measuring spoons. Use this activity to introduce learners to catapults, forces, and levers.

In this activity about physical stress (page 28 of PDF), learners discover that muscles and bones need to work to stay strong.

In this chemistry activity, learners make indicator solution from red cabbage. Then, learners test everyday foods and household substances using the cabbage juice indicator.

This game teaches ratio and proportion by having learners make "salads" that combine three types of beans in different combinations.

In this activity about heart health (on page 34 of the PDF), learners measure their own blood pressure using an electronic blood pressure monitor with a self-inflating cuff (included in cost of materi

In this activity, learners will explore trends in shark populations using shark landing data from the National Marine Fisheries Service.

In this math activity, learners collect, organize, and analyze a set of data related to types of animals in the temperate forest.

In this activity, learners investigate how geometry plays a role in perspective.

This activity (on page 3 of the PDF under GPS: Roller Coaster Design Activity) is a full inquiry investigation into g-force and acceleration.

In this activity, learners will make cleaning up more fun with predictions and counting. Estimate how many things are on the floor (or table), then count as they are picked up.

In this activity, learners model a population of deer and see how the number of deer changes over time.

In this experiment, pairs of learners explore how cold water affects circulation. The mammalian diving reflex (MDR) slows circulation when the body is exposed to cold water.

This is an activity (located on page 3 of the PDF under Butterfly Wings Activity) about how visible light is affected by tiny nanoscale structures, producing iridescence on butterfly wings, soap bubbl

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 quick activity (page 1 of PDF under SciGirls Activity: Kites), learners will witness firsthand the effects of Bernoulli’s Principle by capturing a ping pong ball in the stream of air created b

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.
