This is an activity about electromagnetism. Learners will use a simple circuit powered by a battery source to investigate the strength of the magnetic field produced by a coil of wire in the circuit. The strength will be indicated by the deflection... (View More)

This is a lesson about magnetism in solar flares. Learners will map magnetic fields around bar magnets and investigate how this configuration relates to magnetic fields of sunspots. This activity requires compasses, bar magnets, and a equipment for... (View More)

This is a lesson about the Genesis mission. Learners are provided background information about the Genesis mission and the three basic types of solar wind that are being detected by the Genesis Ion Monitor (GIM) and Genesis Electron Monitor (GEM).

Audience: High school

This is an activity about mapping magnetic fields. Learners use a test magnet to create a map of the magnetic field region around a bar magnet. A Magnaprobe, or other similar test magnet, is required to do this activity. This is the third activity... (View More)

This is lesson to begin learners' thinking about magnetic influence. Learners will watch a classroom demonstration about the effect of magnets on iron filings and then complete a journal assignment to record their reactions and thoughts. This is the... (View More)

This is a lesson about radiation and the various sources of radiation that a spacecraft may encounter in its journey. Learners will calculate their annual exposure to high-energy radiation, identify sources of high-energy radiation, and explain why... (View More)

This is a lesson about radiation and the use of the scientific method to solve problems of too much radiation. Learners will build snow goggles similar to those used by the Inuit (designed to block unwanted light, while increasing the viewer’s... (View More)

This is a lesson about the energy output of the Sun. Learners will consider the essential question, "How much energy does sunlight provide to the Earth and what is its role in the Earth’s energy resources?" Activities include building a device to... (View More)

Audience: High school
Materials Cost: $1 - $5 per group of students

This is an online lesson which introduces the concept of astronomical filters and their connections to imaging different objects in space. Learners will explore perceptions of images as seen using different colors of light, construct a filter wheel,... (View More)

Audience: Middle school, High school
Materials Cost: Free

In this activity, learners will explore the properties of color filters and filter bandpass by observing light sources using diffraction grating and color filters and create a graph of percent transmission versus wavelength to characterize the... (View More)
