Does the space shuttle have an odometer? Maybe, but all that is needed to determine the distance to the moon is a little geometry! The lesson asks scholars to sketch the relationship of the Earth and moon using shadows of an eclipse....

In this moon worksheet, students read about the data collected from the Deep Impact/EPOXI and Cassini missions to the moon that have detected the presence of hydroxyl molecules under the moon's polar craters. Students solve 4 problems...

In this moon image worksheet, students determine the scale of an image taken by the LRO satellite of the Apollo 11 landing site. Students calculate the sun's angle at the time of the photograph using the shadow of the Lunar Lading...

Third graders discuss how Aristotle concluded that the Earth was round. As a class, they review theories about the Earth's shape and describe how life on Earth would be different if it were flat. Individually, they make a moon book in...

Students discover how Aristarchus, a Greek astronomer around 230 BC, used a simple observation of the eclipse of the Moon, plus clever reasoning, to deduce the distance of the Moon. They practice the same calculation technique.

In this lunar surface learning exercise, students use an image taken by the LRO satellite to investigate the size of craters on the moon's surface, to determine the crater density and to find the average distance between the craters.

In this lunar boulders worksheet, students use an image taken by the LRO satellite of the surface of the moon to find the scale of the image and determine the number of boulders and their approximate sizes.

In this travel time of light worksheet, students read about the NASA satellites and space probes that transmit radio signals at the speed of light across huge distances. Students solve 3 problems about data transmission from space to...
