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 observation. Learners will make a 3-dimensional model of a mock planetary surface inside a box, and then place a lid on top. They will then introduce a simple probe, such as a pencil or stick, at various points through... (View More)

This is an activity about craters. Learners will toss rocks of varying sizes into a bin of flour and cocoa. By varying the size and speed of the rocks, learners will determine how the impactors affect the shape and depth of the resulting crater.... (View More)

This is an activity about classifying planetary characteristics. Learners will analyze the provided information about each planet in order to make graphs and Venn diagrams. Then, using both, learners will identify similarities and differences of the... (View More)

In this activity, learners build a sextant to measure the altitude, or height above the horizon, of an object. The activity was originally designed to accompany a previous NASA-funded educational program, entitled The Sun in Time.

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 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)
