Learners will weigh themselves on scales modified to represent their weights on other worlds to explore the concept of gravity and its relationship to weight. They consider how their weights would be the highest of all the planets while standing on... (View More)

Keywords: Jupiter; Mass; Weight

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)

Keywords: Jupiter; Gravity

This is a lesson about visual spectra. Learners will explore different ways of displaying visual spectra, including colored "barcode" spectra, like those produced by a diffraction grating, and line plots displaying intensity versus color, or... (View More)

This is a website about asteroids and comets. Learners can play a physics-based asteroid game, learn about how backyard astronomers are contributing to asteroid research, or simulate an asteroid impact using a Google Earth Impact simulation.... (View More)

Audience: Informal education
Materials Cost: Free

This is a lesson about spacecraft communication. Learners will explore the concepts of "signal" and "noise" by listening to a computer-generated signal from two different distances with no additional background noise, and then with background noise,... (View More)

Audience: Elementary school
Materials Cost: Free

This is a lesson about discovering distant planets using an Earth-based observing technique called stellar occultation. Learners will explore how a stellar occultation occurs, how planetary atmospheres can be discovered, and how planetary diameters... (View More)

This is an activity about parallax. Learners will explore the concept of parallax and then simulate the discovery of Pluto with a Blink Comparator via an online interactive.

Audience: Elementary school, Middle school
Materials Cost: Free

This is an activity about motion in a frame of reference. Learners will develop an understanding that motion is relative by reading the text "Frames of Reference." As a follow-up to the reading, students engage in a writing-to-learn strategy that... (View More)

Audience: High school

This is an activity about shape. Learners will investigate that the Earth is a sphere by comparing the length of shadows from nails arranged on a flat map compared to nails arranged around a spherical globe. From the observations collected, they... (View More)
