This is an activity about the relation between day length and temperature. In one team, learners will create and analyze a graph of hours of sunlight versus month of the year for a number of latitudes. In another team, learners will graph... (View More)

Learners will relate the concept of density to the density of dust in space. They will use mission data from the Student Dust Counter (SDC) data viewer to determine the density of dust grains in a volume of space in order to answer questions... (View More)

Learners will construct a pinhole camera and, using the projected image of the Sun, calculate its diameter. After calculating the diameter of the Sun, learners will create a classroom sized scale model of the Sun and Earth. This activity requires... (View More)

In this lesson, students observe the surface of rotating potatoes to help them understand how astronomers can sometimes determine the shape of asteroids from variations in reflective brightness.

Learners will construct a model to show the relative size and scale of the Sun-Earth system, investigate the visible and electromagnetic spectrums, discuss solar flares and solar weather, develop a UV shield, and discuss the results of their... (View More)

This is a lesson about detecting ice on the permanently shadowed craters of Mercury and the Moon. Learners will consider what might be in that ice and will examine why the polar regions of Earth, Mercury and the Moon are colder than elsewhere on the... (View More)

This is a lesson about the field of astrobiology, the study of life in the universe, and ice as a preservative for evidence of life. Learners will consider the relationship between ice and life as they investigate the conditions required for life to... (View More)

This is a lesson about the magnetic field of a bar magnet. The lesson begins with an introductory discussion with learners about magnetism to draw out any misconceptions that may be in their minds. Then, learners freely experiment with bar magnets... (View More)

Audience: Middle school

This is a lesson about magnetism and solar flares. Learners will evaluate real solar data and images in order to calculate the energy and magnetic strength of a solar flare moving away from the Sun as a coronal mass ejection. This is Activity 3 in... (View More)
