In this activity, learners will measure the length of their shadow from the Sun and compare it three to four months later.

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

In this "game," learners explore and relate the evolution of stars to a Navajo creation story. The story is written on a series of cards, which are laid on a table as the story is told.

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 mimic remote sensing. Learners use a stick to measure the distance to a "planet surface" they cannot see, and create their own map of the landscape.

In this activity, learners act as the Earth and observe how different angles between the Sun, Earth, and Moon affect the phases of the moon we see each month.

In this activity, learners build a scale model of the solar system using a roll of toilet paper.

This is a classic exercise for visualizing the scale of the Solar System.

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

This interactive demonstration reintroduces learners to three states of matter (solid, liquid, gas), and introduces them to a fourth state of matter, plasma.

Many people think the different stages in the life of a star are actually different types of stars, rather than just stages in the life of a single star.

This fun and simple hands-on astronomy activity lets learners make 3-dimensional models of the Earth and Moon.

In this activity, learners add food coloring to hot and cold water in order to see how fluids at different temperatures move around in convection currents.

In this activity (page 95 of the PDF), learners create Escher Staircase models similar to those that were used by Neurolab's Spatial Orientation Team to investigate the processing of information about

In this activity, learners take core samples of candy bars with a straw and carefully observe & excavate their sample, modeled after what the NASA Perseverance rover will do on Mars.

This Exploratorium activity can be used in many contexts because geysers are great opportunities for learning about heat and temperature changes as well as geological/space science phenomena.

In this activity, learners create a "mini sky" in a glass of water in a dark room.

Using information from the My Place in Space lithograph, learners write and/or draw a postcard to friends and family as if they had gone beyond the interstellar boundary of our Solar System, into the

In this activity, learners observe the moon each night for a month and draw their observations in a Moon Watch Log.
