This is an activity about electromagnetism and the Sun. First, learners will do a KWL activity using six vocabulary words. Next, they will build an electromagnet and investigate how it works. Finally, learners will relate the workings of their... (View More)

This is an activity about similarities and differences between the Earth and Mars. Learners will investigate how Mars compares to the Earth, working together to create an Earth-Mars Comparison Poster to post in the program facility/library and share... (View More)

Audience: Informal education

This is a demonstration about the density of the planets. Learners will compare the relative sizes and masses of scale models of the planets as represented by fruits and other foods. They will then dunk the "planets" in water to highlight the fact... (View More)

Learners will model the gravitational fields of planets on a flexible surface. Children place and move balls of different sizes and densities on a plastic sheet to develop a mental picture of how the mass of an object influences how much effect it... (View More)

This is an activity about impact craters. Learners will experiment to create impact craters and examine the associated features. Then they observe images of lunar craters and explore how the mass, shape, velocity, and angle of impactors affects the... (View More)

This is an activity about comparing images of the Sun in different wavelengths of light. Learners will examine solar images taken by the SOHO spacecraft to look for differences in the features that are visible in the various wavelengths of light.... (View More)

This is an activity about the periodicity of the solar cycle. Learners will calculate the number of M-class solar flares as a percentage of the total number of X-ray solar flares and graph these results as a function of time. When compared to a... (View More)

Materials Cost: Free

This is an activity about Earth's magnetosphere. Using provided information, learners will determine the speed of electromagnetic radiation and the speed of material ejected from a solar flare and calculate when each will reach Earth. This is the... (View More)

Audience: Middle school

This is an activity about the solar activity cycle. Learners will construct a graph to identify a pattern of the number of observed sunspots and the number of coronal mass ejections emitted by the Sun over a fifteen year time span. A graphing... (View More)

This is an activity about the movement of a coronal mass ejection. Learners will plot the path of two coronal mass ejections (CMEs), both the distance traveled and the increasing angular width, as they leave the Sun and travel outward through the... (View More)
