Learners will use trays of sand and cups of water to recreate surface features seen in images of Mars. This is activity 5 of 9 in Mars and Earth: Science Learning Activities for After School.
In this activity, students experiment to test the hypothesis that Mars was once hotter. The activity requires some advance preparation by the teacher: the day before the activity, need to place a plastic bottle filled with water in the freezer.... (View More) Materials needed include plastic bottle of water and thermometer.

Also included are tables listing the instrument parameters and the major institutions involved. Kepler is a spaceborne telescope specifically... (View More) designed to survey our region of the Milky Way galaxy to detect and characterize hundreds of Earth-size and smaller planets in or near the habitable zone. The habitable zone encompasses the distances from a star where liquid water can exist on a planet's surface. Note: The fact sheets states that the Kepler Telescope was launched in 2007 but did not launch until 2009. (View Less)
This is a hands-on demonstration of the communication path between the Extreme Ultraviolet Explorer (EUVE) satellite and a scientist on Earth, where students play the parts of various satellites, ground stations, and science centers. The module... (View More) includes a Java applet animation of the Satellite data flow and background information on the various communication links. The purpose of this lesson plan is to show students how the data are sent and received by making students active participants in the chain of events. This demonstration also allows students to get a feel for the dynamic of satellite communications and orbital motion around the Earth. (View Less)
