Day 1
Introduction
1. Teacher will begin the class with an introduction to Mars and why we are studying it as a planet: because it closely resembles Earth in size and rotational speed, and also because we now have evidence that water once existed on this neighboring planet.
2. Have the students respond to the following prompt in a journal or notebook to get their thinking started: If we could no longer support life on Earth, what qualities would we have to look for in a new planet? What would we need in order to make life as close to what we have on Earth now?
Planetary Rotation and Revolution
3. Using the PowerPoint slideshow included in this lesson plan, engage the students in a discussion of the concepts of rotation and revolution and the differences between the two.
4. Discuss how the Earth’s revolution is the cause of the Earth’s 365-day year and how the tilt of the Earth’s axis causes us to experience seasons as we revolve around the sun.
3. Discuss how the rotation of the Earth around its axis, which takes a little under 24 hours, is responsible for the length of the Earth’s day.
4. Compare the length of the Earth’s rotation and the length of the Earth’s revolution to those of Mars, based on the chart on planetary motion in the PowerPoint show—how does the Martian day and year compare to that of Earth? Have the students draw a diagram representing the differences between the planets.
5. Scientists often look to Mars as a place where humans could potentially live in the event that Earth is no longer habitable—how would the differences in the speed of rotation and revolution affect life on Mars?
Day 2
Introduction
1. Teacher should have on the board the steps to the design method so that during the lesson students can reference the process while they work. Write the following on the board:
The Design Process
- Identify the problem or opportunity
- Investigate the problem or opportunity: Gather and analyze information through interviewing, observing, documenting, modeling, weighing choices, identifying your client
- Frame/Reframe the problem: Make sure that you have identified the right problem to solve
- Generate possible solutions
- Edit/Develop ideas: talk with your group about what ideas have the most potential
- Evaluate your ideas
Create your solution: Create diagrams, models, and presentations; organize your resources and notes
- Re-Evaluate your solution: Take feedback and analyze how you could make your solution even better
2. Teacher should pass out a copy of the article to each student and have them take out their journals or notebooks to take notes on what they find interesting or what they have questions about while reading
The Mars Rover- problems and possibilities
3. Using your favorite technique, have the students read the article on NASA’s Mars Rover program and the recent challenges it has faced due to the oncoming Martian winter (I find it works best when students are reading aloud).
4. Have the students answer the three discussion questions at the end of the article in their notebooks independently and then discuss the results as a class when they are done.
5. Using the Design Method on the board, have students, in groups of two, work through the steps of the design process using the information in the article. The goal here is to use the information presented in class the day before along with the article to identify the problems with the Rover as it is—possible problems the students could identify are that the scientists didn’t account for the lack of sunlight and should have included a backup power source on the rover, the scientists should have programmed the Rover to change locations during the winter in order to get more sunlight, scientists should have launched the Rover sooner in the Martian year, etc.
6. Have the student pairs or groups of 3 come up with a solution to the Mars Rover problem, whether it’s a new design for the Rover itself or a change in the execution of the program.
7. At the end of the class period, have groups share some of their ideas of changes to the NASA program and how it might help solve the Rover problem.
