Why Does the Moon Have Phases?
Source Institutions
In this activity, learners use a simple 3D model to discover why the Moon has phases.
Creating Craters
Source Institutions
In this activity, learners will investigate how craters are made and the different factors that contribute to size left from the impact.
Kid Moon: Splat!
Source Institutions
In this activity, learners model ancient lunar impacts using water balloons.
Aerogel
Source Institutions
This activity/demo introduces learners to aerogel, a glass nanofoam. Learners discover how aerogel is made and how well it insulates as well as learn about aerogel's other unique properties.
Moon's Long History: Impact Paintings
Source Institutions
In this activity, pairs of learners model how scientists use craters to determine the ages of lunar surfaces. One partner keeps time while the other creates a painting for the other to interpret.
Space Rocks!: A Meteorite Game
Source Institutions
In this board game, learners explore the origins of meteors, meteoroids, and meteorites as well as the their characteristics and importance. They also discover some misconceptions about meteors.
Height Sight
Source Institutions
In this activity, learners build a tool called an inclinometer that can find the height of any distant object, from a tree to the North Star.
Make a Comet on a Stick
Source Institutions
In this activity, learners craft their own model of a comet on a stick to make it fly around the room.
Exploring the Solar System: Mission to Space Board Game
Source Institutions
In this tabletop board game, players will represent a team of scientists and engineers sending a spacecraft on a mission to space.
Exploring the Solar System: Stomp Rockets
Source Institutions
In "Exploring the Solar System: Stomp Rockets," participants learn about how some rockets carry science tools—not scientists—into space, and how a special kind of rocket called "sounding rockets" can
Model the Sun and Earth
Source Institutions
In this activity, learners make scale models of the Sun and Earth out of paper mache.
Experiencing Parallax With Your Thumb
Source Institutions
In this activity, learners investigate parallax, a method used to measure distances to stars and planets in the solar system.
Chances Are: OH NO! Look Out Below for a UFO
Source Institutions
In this math lesson (on Page 13), learners predict and simulate the likelihood of an event occurring.
Eclipse Flipbook
Source Institutions
In this activity, learners make flipbooks of drawings showing the progression of a Total Solar Eclipse.
Solar Flare Flip Book
Source Institutions
In this activity, learners make their own flip book that shows real solar flares erupting from the Sun in November 2000. Step-by-step instructions are included with photos.
Exploring the Solar System: Mars Rovers
Source Institutions
In "Exploring the Solar System: Mars Rovers," participants learn about how scientists and engineers use robotic rovers and other vehicles to explore distant worlds, and experience some of the challeng
How to View a Solar Eclipse
Source Institutions
This is an activity to do when there is a solar eclipse!
Moon and Stars
Source Institutions
In this craft activity, learners create a string of cut-out moons and stars.
Pie-Pan Convection
Source Institutions
It's difficult to see convection currents in any liquid that's undergoing a temperature change, but in this Exploratorium Science Snack, you can see the currents with the help of food coloring.
Glass and Mirrors: An Inside Look at Telescopes
Source Institutions
This hands-on astronomy activity allows you to create a “cutaway” telescope to clearly show how reflector and refractor telescopes work.
