In this activity, learners shrink the scale of the vast solar system to the size of their neighborhood.

In this activity (on page 142 of the PDF), learners will compare breathing rates before and after hyperventilation to explore how reduced carbon dioxide levels in the blood lower the need to breathe.

In this three-part activity, learners use food to determine the effects of wind, sandblasting and water on regolith (dust) formation and deposition on Earth.

In this activity, learners will explore how maps can provide information about a place and help us find our way from one location to another.

In this activity, learners will discover how our universe is continuously expanding.

In this activity, learners discuss how life is defined and conduct a simple experiment, looking for signs of life in three different “soil” samples.

In this activity, learners predict whether a ball on Earth or a ball on the Moon bounces higher when dropped and why.

In this astronomy activity, learners create a model of the solar system using beads and string.

In this activity, learners will create their very own constellation.

In this activity, learners create volcanoes like those they have examined on Earth and Mars through images taken by spacecraft.

In this hands-on activity, learners simulate the crashing and smashing of a meteor impact using household cooking supplies.

In this activity, learners create channel features with flowing water, comparing their observations to real images of Mars and Earth taken by satellites/orbiters.

In this activity, learners work in pairs to measure each other's ankles with lengths of string.

In this activity, learners experience some of the challenges of "tele-operating" a robotic vehicle on another planet when they design and execute a series of commands to guide a human "rover" through

In this activity, learners cut out and fold their own collapsible origami starshade, an invention that shields a telescope's camera lens from the light of a distant star so that NASA scientists can ex

Learners use simple materials to construct a model the Big Dipper. Learners hang the model from a doorway or ceiling and look up at it to see the constellation as seen from Earth.

In this activity, learners simulate a multistage rocket launch using party balloons, fishing line, straws, and a plastic cup.

This fun and simple hands-on astronomy activity lets learners experiment with a bucket, stretchy fabric, marbles, and weights to discover some basics about gravity.

"Exploring the Solar System: Craters" is an active, hands-on activity that demonstrates how craters form, and what they can teach us about the history and composition of planets and moons.

In this activity, learners use a toaster to generate wind and compare the appliance's heat source to Jupiter's own hot interior. Learners discover that convection drives wind on Jupiter and on Earth.
