Using a Simple Astrolabe
Source Institutions
In this activity, learners use an astrolabe to measure the altitude of objects. Learners will first practice taking measurements by measuring the altitude of trees and buildings.

Light is Made of Colors
Source Institutions
Learners observe different light sources, outdoors and indoors, using prism glasses (diffraction glasses) and color filters.

Particle Detection
Source Institutions
By tossing, collecting, and sorting beanbags, learners understand how the IBEX spacecraft uses its sensors to detect and map the locations of particle types in the interstellar boundary.

Solar Water Heater
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.

Mars from Above: Viewing Volcanoes
Source Institutions
In this activity, learners create volcanoes like those they have examined on Earth and Mars through images taken by spacecraft.

The Shadow Knows I
Source Institutions
In this activity, learners will measure the length of their shadow from the Sun and compare it three to four months later.

Make An Impact
Source Institutions
In this hands-on activity, learners simulate the crashing and smashing of a meteor impact using household cooking supplies.
Cycles in the Cards
Source Institutions
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.
Why is the Sky Blue?
Source Institutions
In this activity, learners create a "mini sky" in a glass of water in a dark room.

Postcards from Space
Source Institutions
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

Rainbow in the Room
Source Institutions
This activity generates learner excitement about light through the creation of a room-sized rainbow.

Building a Magic Carpet
Source Institutions
In this activity (page 89 of the PDF), learners compare and contrast pitch and roll motions by using a Magic Carpet maze similar to one that was used for Neurolab investigations about microgravity.

The Size and Distance of the Planets
Source Institutions
In this activity, learners investigate the concepts of relative size and distance by creating a basic model of the solar system.

House Warming
Source Institutions
In this physical sciences activity, learners explore how passive solar design increases energy efficiency.

Breathing Machine
Source Institutions
In this activity, learners work in teams to construct human lung models from small plastic beverage bottles and balloons.

Comet Cratering
Source Institutions
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.
Any Year Calendars
Source Institutions
This PDF contains 12 calendars (12 months). Each month contains activities about math. Things to do on familiar holidays (like July 4), less common holidays (like Backward Day), and any day.

Our Solar System to Scale
Source Institutions
In this activity, learners plan and create a 24-foot long, two-dimensional model of our solar system, and compare and contrast the differences between planets and the sun.

Finding the Size of the Sun and Moon
Source Institutions
In this activity, learners build a simple pinhole viewer. They use this apparatus to project images from a variety of light sources, including a candle, the Sun, and the Moon.

Regolith Formation
Source Institutions
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.
