"Exploring the Universe: Objects in Motion" encourages participants to explore the complex but predictable ways objects in the universe interact with each other.

In this activity, learners carry out a scientific investigation of dust in their classroom. Learners produce an analysis on graph paper of the dust they collect over the course of a few days.

In this activity, "space cadets" (learners) use writing and sequencing skills in addition to directional words/ordered pairs to guide Buzz Lightyear (from the movie "Toy Story") through a grid to reac

This fun and simple hands-on astronomy activity lets learners experiment with marbles and weights to discover some basics about gravity and black holes.

In this collaborative storytelling activity, learners and caregivers develop a strong story about science and exploration.

In this design challenge activity, learners design and build a solar hot water heater. Their goal is to create a heater that yields the highest temperature change.

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

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

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.

Make impact craters with marbles (or rocks or washers) in a container of flour. Find out what you can learn about your "comets" by the craters they make.

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.
