This is a lesson about the solar wind, Earth's magnetosphere, and the Moon. Participants will work in groups of two or three to build a model of the Sun-Earth-Moon system. They will use the model to demonstrate that the Earth is protected from... (View More) particles streaming out of the Sun, called the solar wind, by a magnetic shield called the magnetosphere, and that the Moon is periodically protected from these particles as it moves in its orbit around the Earth. Participants will also learn that the NASA ARTEMIS mission is a pair of satellites orbiting the Moon that measure the intensity of solar particles streaming from the Sun. (View Less)
This is a lesson about using radar to search for water on the Moon. Learners will use images to search for water on the moon. Additionally they will learn how Mini-RF can identify surface features that are permanently shadowed, or lack any visible... (View More) evidence of surface morphology. (View Less)
This is a lesson about the shape of objects in space. Learners will observe the surface of rotating potatoes to help them understand how astronomers use variations in reflective brightness to determine the shape of asteroids.
This educational wallsheet provides several simple illustrations of Newton's Second Law. In the activity included, students study the motion shown in the drawings to decide how it relates to the object's velocity, whether or not the velocity is... (View More) changing (acceleration), and what forces are causing any acceleration. Activity worksheets are easily copied for use in the classroom with only the addition of paper and pencils. The activity provides teachers with background information, pre-activity reading, pre-activity discussion questions, an assessment, an extension activity for advanced students, and post-activity discussions that tie the classroom activity back to the Swift satellite launch. This is the second of four posters on Newton's Laws. A copy of the wallsheet intended to accompany the activity is available on this website. (View Less)
This is an activity about spectroscopy. Learners will build a spectroscope with a scale for measuring wavelength and use it to observe various light sources. They will identify spectral lines in more than one light source and analyze the collected... (View More) data. This activity requires diffraction grating material, several light sources, and gas emission lamps and power sources. (View Less)
This is a activity about how reaction wheels affect spacecraft orientation (attitude). Learners will observe Newton's Third Law (action-reaction) in the changes caused by a reaction wheel acting upon a spacecraft suspended from a support wire and in... (View More) the ensuing interfering forces from the wire support. The experiment includes an option for demonstration and for learner investigation. Notes about gyroscopes are included. (View Less)
