Light on Other Planets
Source Institutions
In this math-based activity, learners model the intensity of light at various distances from a light source, and understand how astronomers measure the amount of sunlight that hits our planet and othe

Oil Spot Photometer
Source Institutions
In this math activity related to light, learners assemble a photometer and use it to estimate the power output of the Sun.

The Geophysical Light/Dark Cycle
Source Institutions
This is an activity (located on page 131 of the PDF) related to sleep and circadian rhythms as well as space travel.

Planet Surfing
Source Institutions
In this astronomy activity (page 6 of the PDF), learners will compare and contrast two planets in the solar system using data obtained from the internet.

Transit Tracks
Source Institutions
In this space science activity, learners explore transits and the conditions when a transit may be seen.

Colors of Stars
Source Institutions
In this activity, learners observe colors in the flame of a burning candle to explore connections between matter, light, color and temperature -- basic concepts of matter and energy.

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.

Telescopes as Time Machines
Source Institutions
This fun, nighttime hands-on astronomy activity lets learners explore how long it takes for light from different objects in the universe to reach Earth.

Build a Solar System
Source Institutions
In this activity, learners make a scale model of the Solar System and learn the real definition of "space." Learners use the online calculator to create an appropriate scale to use as a basis for thei

Measure the Sun's Size
Source Institutions
In this activity, learners make their own pinhole viewer in order to measure the size of the sun.

LEGO Orrery
Source Institutions
Use this model to demonstrate the goal of NASA's Kepler Mission: to find extrasolar planets through the transit method.

Our Place in Our Galaxy
Source Institutions
In this fun and simple hands-on astronomy activity, learners construct a model of our place in the Milky Way Galaxy and the distribution of stars, with a quarter and some birdseed.

The Thousand-Yard Model
Source Institutions
This is a classic exercise for visualizing the scale of the Solar System.

Properties of Dust
Source Institutions
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.

Canned Heat
Source Institutions
In this activity, learners explore how light and dark colored objects absorb the Sun's radiations at different rates.

Model the Sun and Earth
Source Institutions
In this activity, learners make scale models of the Sun and Earth out of paper mache.

Investigating Ice Worlds
Source Institutions
In this activity about the solar system, learners use various light sources to examine ice with different components to understand how NASA studies planets and moons from space.

Earth's Energy Cycle: Albedo
Source Institutions
In this activity, learners experiment and observe how the color of materials that cover the Earth affects the amounts of sunlight our planet absorbs.
