Students are introduced to the planet Mars. They begin by discussing the location and size of Mars relative to Earth, as well many interesting facts about this "red planet" such as its size relative to other planets in the solar system. Next, the history of Martian exploration is reviewed and students discover why researchers are so interested in studying this mysterious planet. The lesson is accompanied by the associated activity to have students gain a better understanding of Mars' positioning through scaling techniques. The lesson concludes with students learning about future plans to visit Mars.
Engineers have played various roles in the long history of exploring the red planet. One of the earliest, Galileo, provided us with a closer view of Mars by his invention of the telescope. In the 1950-60s, engineers developed rockets and probes that provided the first, up-close visuals of the planet. Engineers also designed and fabricated surface exploration equipment. Engineers continue to work with scientists to develop reliable orbiters, rovers, aircraft and human transport for future missions.
After this lesson, students should be able to:
- Discuss the environment on Mars.
- Give examples of how technology has allowed us to study Mars.
- Explain the challenges in exploring Mars.
- Give examples of how technology is changed as new knowledge of Mars is acquired.
