This activity (page 2 of the PDF under SciGirls Activity: Double Dutch) is a full inquiry investigation into whether hearing or seeing has a bigger effect on jump rope performance.

In this activity on page 24, learners perform experiments to examine whether or not trash can float, blow around, or wash away.

In this activity, learners explore the different heating properties of soil and water.

In this activity on page 27, learners perform an experiment to learn about how different types of marine debris degrade and how weather and sunlight affect the rate of degradation.

In this math lesson (on Page 13), learners predict and simulate the likelihood of an event occurring.

In this activity, learners make an equatorial sundial, which is simple to construct and teaches fundamental astronomical concepts. Learners use the provided template and a straw to build the sundial.

In this activity, learners explore how anemometers work to record wind speeds and how the equipment has undergone engineering adaptations over time.

In this outdoor, beach activity, learners use tennis balls, water balloons and other simple devices to investigate the movement of waves and currents off a sandy beach.

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.

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

In this activity, learners explore conservation of energy by experimenting with a solar cell light device.

In this activity, learners simulate the energy transfer between the earth and space by using the light from a desk lamp desk lamp with an incandescent bulb and a stack of glass plates.

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.

In this activity, learners examine the different materials gardeners add to their soil, and discuss how these materials are important for plant growth.

Learners work in teams to design and build solar water heating devices that mimic those used in residences to capture energy in the form of solar radiation and convert it to thermal energy.

In this activity, learners calculate the number of milliliters of water a nearby tree transpires per day.

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 explore and experiment how we can use our bodies everyday to get from one place to another.

In this activity, learners investigate wind by comparing the force of wind in different locations. Learners build wind-o-meters out of wooden sticks and strips of paper.
