This is a lesson about sampling and estimation. Learners will make an object called a sampling window through which they will first count the number of stars on a printed page and estimate the total number of stars on the page, then count and... (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.
