This is an activity about comet motion. Learners will cut out images of Halley's Comet, putting the images in sequential order to create a flip book demonstrating the comet's orbit around the Sun and the formation of the comet's tail near the Sun.... (View More)

This is an activity about telescopes. Learners will first measure several circles to determine their diameters and calculate their areas. Afterwards, they will cover each circle entirely with pennies and record how many pennies are needed for each... (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 aobut size and scale in the solar system. Learners will cut out descriptions of various objects and distances and then match those descriptions to an actual metric measurement. This is Activity D-1 of Universe at Your Fingertips... (View More)

This is an activity about size and scale. Learners will use common objects to create a size and distance model of the Solar System, with a peppercorn representing the size of the Earth. Using paces or steps as a form of standard measurement,... (View More)

The students will learn to identify watersheds on topographic maps by learning how to interpret contour lines and distinguish adjacent watersheds by the ridge line between them. Required materials include laminated 7.5 topographic maps of a local... (View More)

This is an activity about investigating students' preconceptions of the Moon's appearance and its phases. Learners will first draw an image of how they think the Moon looks and then discuss as a group why the drawn pictures may vary. Then, learners... (View More)

This is an activity about constellations. Learners will first draw familiar pictures and shapes within circles to introduce the concept of pattern recognition, then create their own unique constellation patterns from an arrangement of dots similar... (View More)

This is an experiment about shadow lengths, geometry, and motion. Learners will use a flashlight and toothpick to create a shadow and will measure changes the length of the shadow as they change the position of the light. This is activity B-1 of... (View More)
