  2. Agenda 1. Engineering Design Process 2. Your Turn 3. Share successes 4. Evaluate Activity

  3. Design Process Identify Problem Share Solution Brainstorm Engineering Process Test & Evaluate Build Design Redesign

  4. Steps to Success Identify the Problem Brainstorm Design Understanding the problem paves the way for solving it. Questions to ask: What is your goal? Can you imagine how others could use this? What are your constraints? How will you know if you were successful? Choose your design: It’s time to be realistic. Will your design work with allowed materials. How will your design work? What is your goal? What will be your steps? Do you have enough time to build your design? There are no wrong ideas. Directing your Students: List your ideas. Examine your materials. What ideas do your materials give you. Sketch out your ideas. Provide background info.

  5. Steps to Success Build Test/Evaluate Redesign Share Solution Now it’s time to build! Directing your Students: Walk around and facilitate the building process. Give suggestions only when necessary to get students unstuck! Students build and test their design. After each test, students evaluate. Students evaluate and redesign as necessary. Ask students: Does your design meet the goal of the task? Why do you often have to make changes to your original design? What can you learn from the other designs. How did you do? Communication and Collaboration Ask students: Were you successful in meeting your goal? Did you design work as you expected? What is the best feature of your design? If you started over now, what would you do differently? Why?

  6. Materials • Card Stock 4X5in. • 3 file cards • 1 cup • 2 regular marshmallows • 10 miniature marshmallows • 5 paper clips • 40 in. kite string • 1 sheet of newspaper

  7. Building your lander TEST/ EVALUATE REDESIGN BUILD First, design a Shock-absorbing System. THINK SPRINGS AND CUSHIONS Second, put your spacecraft together Third, add a cabin For the astronauts. Attach the cup to the platform. Add the astronauts. (The cup must stay Open—no lids.) Test the lander design by dropping the lander from 3 feet to see what adjustments you should make. Make Adjustments.

  8. Designing Your Parachute TEST/ EVALUATE BUILD REDESIGN Next, design a parachute. THINK FLOATING LIKE A FEATHER. Attach parachute and test. Make changes to improve results. Drop from parachute drop and evaluate Success. Consider other Options. Bigger Springs, different Size or shape parachute.

  9. Discussion QUESTIONS • What forces affected your lander as it fell? • After testing, what changes did you make to your lander? • Engineers’ early ideas rarely work out perfectly. How does testing help them improve your design? • What did you learn from watching others test their landers? • Mars is covered in a thick layer of fine dust. How might this affect your landing?
