Title: The Technology of Mars Exploration
Description: This lesson, from Xpeditions, asks students to research the types of technology that are used to map and explore Mars. Students imagine that they are working as technology experts for NASA and create visual presentations to show the American public the types of technology that their tax dollars are funding for Mars mapping and exploration.

Subject: Health, Science
Description: The purpose of this lesson, from Science NetLinks, is to learn about sources of high-energy radiation and calculate student exposure to ionizing radiation over the past year. In the first part of the lesson, students calculate their yearly exposure rate to harmful high-energy radiation and cumulative effects over time. They then use the information to evaluate the various sources of radiation that are of greatest concern for them. In the second part of the lesson, students learn that spacecraft and other objects in space must be concerned with the same kinds of radiation to which humans are exposed.

Title: Mars Earth Orbit - Model
Description: This student interactive, from Illuminations, uses circular orbits to approximate the paths of Mars and Earth. Users can view a diagram depicting the orbits of both planets around the sun and see how their relationship to one another changes as they complete their orbits.

Title: Mars Earth Orbit - Actual
Description: This student interactive, from Illuminations, uses the actual distances and speeds of the planets to simulate the relative positions of Earth and Mars. Because the center of the Earth s orbit is approximately the Sun and the center of Mars orbit is about 22 million miles from the Sun, the orbits of the two planets are closer to one another on one side of the Sun than on the other side. The interactive illustrates this fact.
