This is a lesson where learners explore how the creation and destruction of ozone protects us from ultraviolet radiation (UV). Learners will kinesthetically model the depletion of ozone caused by chlorofluorocarbon (CFC) molecules; use ultraviolet... (View More)

In these activities, students investigate how gamma ray bursts emit energy in beams (as opposed to emitting light in all directions) and investigate the implications of this on the total number of gamma ray bursts seen in the universe. This activity... (View More)

In this activity, students determine the direction to a gamma ray burst using the times it is detected by three different spacecraft located somewhere in the solar system. We assume that all the spacecraft are in the plane of the Earth's orbit... (View More)

In this activity, students look at the distribution of aluminum foil balls arranged in a circle on the floor, and compare them to the distribution of gamma-ray bursts on the sky. This activity is part of a unit designed to use gamma-ray bursts -... (View More)

In this hands-on activity, students analyze the data on Mystery Object Cards, observe that astronomical objects have many observable properties, and discover that these properties allow scientists to categorize astronomical objects into different... (View More)

Learners will design and conduct experiments to answer the question, "how does distance and inclination affect the amount of heat received from a heat source?" They will measure heat change as a function of distance or viewing angle. From that... (View More)

This is a lesson about infrared radiation. Learners will investigate invisible forms of light as they conduct William Herschel's experiment and subsequent discovery of infrared radiation. They will construct a device to measure the presence of... (View More)

This activity deepens student understanding of the electromagnetic spectrum, enabling students to detect and consider wavelengths other than visible light. They learn how these other wavelengths can be used to "see" things we cannot see with our... (View More)

Audience: Middle school

One of the greatest mysteries of all is what causes gamma ray bursts. These bursts are the most powerful explosions in the Universe and occur about once a day. Their origin is unknown, although there are several theories. Students learn about NASA's... (View More)

Audience: Middle school

In this activity, students demonstrate the relationship between wave frequency and energy in the electromagnetic spectrum by shaking a rope to identify the relationships. This activity is part of Unit 2 in the Space Based Astronomy guide that... (View More)
