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)

Audience: Middle school, High school
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 a lesson about making careful observations. Learners will get to know the surface of an unshelled hard-boiled egg and try to draw and sketch the surface features of their egg in sufficient detail so that a person in another group will... (View More)

This is an activity about critical observation skills. Learners will receive an egg to record its features from various vantage points, illustrating their size, shape, and location. They will then try to identify and recognize the surface features... (View More)
