In this activity, students compute the strengths of the gravitational forces exerted on the Moon by the Sun and by the Earth, and demonstrate the actual shape of the Moon's orbit around the Sun. The lesson begins with students' assumptions about the... (View More)

This is an activity about oscillation. Learners will observe, time, and graph the data of the side to side motion of the mirror used in the soda bottle magnetometer activity to determine the mirror's oscillation amplitude. This activity requires... (View More)

This is an activity about gravity. Learners will design their own experiments to explore the fundamental force of gravity and then extend their thinking to how gravity acts to keep objects like moons and ring particles in orbit. They use the... (View More)

This is an activity about the moons of Jupiter. Learners will study the orbital motions of Jupiter's Galilean satellites. The relationship between distance, gravity, and orbital period will be explored. This activity is part of "Ways of Seeing," an... (View More)

This is an activity about cratering. Learners will observe and identify distinctive features of craters. This exercise will help students grasp how craters provide information about the history of the solar system. This activity is part of "Ways of... (View More)

In this activity, learners will determine the factors affecting the appearance of impact craters and ejecta on the Moon. Extensions are listed. This activity is in Unit 2 of the Exploring the Moon teachers guide, which is designed for use... (View More)

This is an activity about gravity. Learners will fill out a questionnaire to assess their ideas about how the Earth is shaped and how things fall here and at different places around the planet. Then, in small groups, learners will discuss how... (View More)

This is an activity about the Doppler effect. Learners will use long springs or ropes to examine the frequency and wavelength of various waves. Then, they will observe a demonstration of the Doppler effect for sound waves, using this understanding... (View More)
