This is a lesson about impact craters; the relationships between crater size, projectile size and projectile velocity; and the transfer of energy in the cratering process. Learners will create plaster of Paris or layered dry impact craters and... (View More)

This is an activity about the size of the Moon. Learners will calculate the diameter of the Moon using proportions. This activity is in Unit 1 of the "Exploring the Moon" teachers guide, which is designed for use especially, but not exclusively,... (View More)

This activity is about scale and distance. Learners will use simple sports balls as scale models of Earth and the Moon. Given the astronomical distance between Earth and the Moon, students will determine the scale of the model system and the... (View More)

This is an activity about observation. Learners will first observe a first quarter Moon and as a group, predict which phase the Moon will be in during the next observation. After this, learners will continue to chart the progress of the lunar cycle... (View More)

This is an activity about telling time. Learners will construct a northern-hemisphere star clock and will set their star clocks based on the position of the Big Dipper in the sky. Then, they will use their star clocks to predict where the Big Dipper... (View More)

This is an activity about spectroscopy. Learners make their own spectroscope and measure the wavelengths of spectral lines. Then, they will record the colors, patterns, and wavelengths of the lines from various light sources. This activity requires... (View More)

This is an activity about science and pseudo-science. Learners will examine the validity of astrology by charting birth dates of U.S. presidents and by comparing horoscopes in different newspapers. After, students will attempt to identify their own... (View More)

This is an activity about size and scale. Learners will construct accurate size models of the Earth and Moon out of clay and use them to model the Earth-Moon distance. This is Actividad 4.1 as part of El Universo a Sus Pies, a Spanish-language... (View More)

In this introductory global change investigation, students gather and record visual and written data from their surroundings, and through analysis, show how the sampling window chosen for examination can affect an outcome, sometimes resulting in... (View More)
