Description
This lesson includes a series of activities that are based on the planet Mars and factors that affect space travel.

Objectives
Students will:
• Compare the positions of planets as they move around the sun.
• Explore expenditures of time and fuel related to space travel.
• Describe what happens on minimum fuel orbits.
• Plot the paths of spacecraft leaving Earth for Mars and leaving Mars for Earth.
• Be introduced to the design process in engineering.
• Solve ratio problems to maximize the mission payload.

Lesson Activities and Sequence

1. Mars Bound
Students will be introduced to the design process, engineering and technology. Students will learn that the design process is not a simple, linear progression from one step to the next, resulting in a finish product. Although there are steps, the design process is an iterative one: designing, modifying, testing and redesigning until a finished product is made. A central tenet of engineering, however, is that there is no such thing as a perfect design.
Keywords: problem solving, scientific method, time, GPS, accuracy, precision, predicting, game, PBL

2. Destination Mars
This lesson is designed to increase students' knowledge, awareness and curiosity about the process of scientific exploration of Mars. As scientists look for evidence of life on Mars, they will focus on how to get there: navigation and trajectory.
Keywords: exploration, trajectory, navigation, planet distances, orbit, arcs, compass use

3. Can We Take It With Us?
Although intended for a lunar mission, this activity works well for Mars as a destination, too. Students work in teams to determine the maximum amount of payload that they can take on a mission. Students are given a container that represents the maximum weight allowed. They are also given a list of mandatory mission ratios, a double balance, 80 pennies and an empty container to weigh their trial payloads. The team closest to the maximum payload weight without going over is declared the winner. See page 27 of the guide.
Keywords: payload, mass, ratio, math calculations, problem soliving, teamwork, estimation, use of balance scale, measurement, moon
