This module focuses on ultraviolet radiation on Earth and in space and how it affects life. Learners will construct their own "martian" using craft materials and UV beads. They will explore how UV radiation from the Sun can affect living things,... (View More)

Audience: Informal education

This is an assessment activity for the The Cosmic Ray Telescope for the Effects of Radiation (CRaTER) educational kit. Learners will make a poster that explains possible origins of cosmic rays, how they affect people, and what protects us here on... (View More)

Audience: Middle school
Materials Cost: 1 cent - $1 per student

This lesson provides a way for students to determine the relationship between the distance from a light source and its brightness. Once students discover the relationship, they can begin to understand how astronomers use this knowledge to determine... (View More)

In this activity about spectroscopy, learners build a spectroscope, learn about graphing spectra, and then identify elements in gas tubes using their spectra. The activity concludes as learners graph the spectra of different materials. Essential... (View More)

This is an activity about the size of the Sun. Learners will construct a pinhole camera and, using the projected image of the Sun, calculate its diameter. After calculating the diameter of the Sun, learners will create a classroom sized scale model... (View More)

This is a unit of 8 sessions about the Sun-Earth system. Learners will construct a model to show the relative size and scale of the Sun-Earth system, investigate the visible and electromagnetic spectrums, discuss solar flares and solar weather,... (View More)

Audience: Middle school

This is a lesson about the shape of objects in space. Learners will observe the surface of rotating potatoes to help them understand how astronomers use variations in reflective brightness to determine the shape of asteroids.

This 28-page coloring and activity book includes general information on X-ray astronomy, Chandra and the STS-93 mission. It also looks at black holes, supernovas, galaxy clusters and more. Each image is accompanied by a summary of information.... (View More)

This is an activity about the electromagnetic spectrum and how the different wavelengths of light are used to capture the most complete picture of objects in space. Learners will view images of our galaxy in multiple wavelengths to compare and... (View More)

Audience: Elementary school, Middle school, High school
Materials Cost: Free

In this activity, identified as the capstone activity, students will be asked to examine and analyze spectra from a past mission and compare it to simulations of data from future missions, including Suzaku. A thorough comparison will show better... (View More)
