Step 1 Identify the Need or Problem Define Problem/Scenario: Your company wants to be hired to design a cost-effective airbag from nonflammable chemicals that will inflate quickly and prevent injury. Expected Task: Build a prototype of an airbag that will prevent an egg from breaking simulating a car crash. Step 2 Research the Need or Problem Research and Citations: Vocabulary: mass, volume, physical change, chemical change, law of conservation of mass, design, solution, test Step 3 Develop Possible Solution(s) Criteria: Costs: 10 mL of vinegar= $500 1 grams of baking soda= $100 Each group should consist of 3-4 students Constraints: Air bag doesn’t explode Protects passenger (egg) from a minimum of 50 cm. Maximum amount of vinegar 50 mL and 5 grams of baking soda Materials: Vinegar Baking soda Meter stick/measuring tape Electronic scale/triple beam balance Plastic sandwich bags Hard boiled eggs Clear plastic cups Graduated cylinders Masking tape Optional: shoebox or plastic container to hold air bag in place. Step 4 Select the Best Possible Solution (s)/ Step 5 Construct a Prototype Building of the Product (Prototype, model or Artifact): Step 6 Test and Evaluate the Solution(s) Testing of the Product (Prototype, model or Artifact): Peer-Review Questions: Did you the budget of materials play a role in your design? How? How did you choose which ratios of vinegar and baking soda to try? What research did you use to design your air bag? What other designs did your team consider? What would you change to improve in the design of your air bag? Step 7 Communicate the Solution(s) Project Summary: Each team will create a presentation (poster, PowerPoint, etc.) of their company’s airbag and the reason their airbag had the most efficient design. Presentation of Final Solution: Students will present their team’s air bag design and budget to the class. They will test to see the maximum height their air bag can maintain the egg passenger safe. A class data chart will be constructed where the ratio of vinegar and baking soda is recorded with respect to the maximum height the egg was “safe” per team.
