In this activity, learners explore how engineers design devices that can detect the presence of pollutants in the air.

In this nighttime, outdoor activity, learners keep a record of what they see in the sky by drawing constellations, the Moon, and making note of the weather and conditions each day.

In this activity, learners are introduced to challenges of maintaining temperatures while living in space.

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 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 archaeology activity, learners make observations and conduct an experiment to demonstrate the effect saltwater has on artifacts.

In this water pollution activity, learners create pond water cultures and investigate the effects of adding chemicals or natural nutrients.

This activity offers learners and their families several ways to raise their awareness together about home water.

In this weather activity (page 10 of the PDF), learners will demonstrate the changes in atmospheric pressure by constructing their own barometer.

Did you know that the water we use today is the same water found on Earth millions of years ago? The Earth constantly uses and recycles water in a process called the water cycle.

In this activity, learners create a CloudSpotter wheel and record the different types of clouds they observe twice daily over several days.

Just like birds, some dinosaurs had air-filled (pneumatic) bones, which made the dinosaurs' skeletons lighter.

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.

This activity (on page 3 of the PDF under GPS: Cactus Activity) is a full inquiry investigation into how some desert birds keep their cool.

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

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

This activity (on page 2 of the PDF under SciGirls Activity: Lift Off) is a full inquiry investigation into the engineering challenges of sending scientific sensors into space.

In this activity, learners investigate the movement caused by dispersion. Learners discover that dispersion is the random movement of objects.

In this activity, learners create a biosphere in a baggie.

In this activity, learners build a model of a self-sustaining habitat (growing grass and beans from seeds).
