This is a lesson about the Discovery Program's exploration of the solar system. Learners will identify and communicate to others the varied space science explorations carried out by the Discovery Program and dig into one mission in depth. They can... (View More)

This is a lesson about remote sensing. Learners will investigate how much you can learn about something just by looking at it. In Activity 1, students study aerial photographs to identify geologic features, determine how they differ from one... (View More)

This is a lesson about how to plan a mission to explore another world in the Solar System. Learners will discuss the path of a spacecraft traveling between planets, examining the journey from the Earth to Mars as an example. In Activity 1, students... (View More)

The purpose of this investigation is to understand the change that takes place when water condenses from a gas to a liquid, and how a change in pressure affects this transformation. Materials needed for the experiment include a large (2L) soda... (View More)

In this activity, students monitor the change that takes place when water vapor condenses from a gas to a liquid and see how a change in temperature affects this transformation. Materials needed to conduct the investigation include two thermometers,... (View More)

This experimental activity is designed to develop a basic understanding of the interrelationship between temperature and pressure and the structure of a device made to examine this relationship. Resources needed to conduct this activity include two... (View More)

This activity promotes student understanding of some of the movements that take place when warmer water and cooler water interface, and how differences in densities, resulting from variations in temperature, set molecules of liquids and gases in... (View More)

This experimental activity is designed to develop basic understanding of the relationship between the angle of light rays and the area over which the light rays are distributed, and the potential to affect changes in the temperature of materials.... (View More)
