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)

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 scale. Learners will use toilet paper squares as a standard measuring unit for a Solar System model and will determine the scaled distance between each planet using the data provided. This is Actividad 4.2 as part of El... (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 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)

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)
