4. Engineering Design Process

15. Project 1 - Make a landfill liner Identify and define: Environmental engineers must piece together liners for real landfills that are acres and acres in size. This is done to prevent contamination of groundwater located near the landfill.

16. Project 1 - Make a landfill liner Gather Information: • Let students loose with technology and information (pictures, videos). • Don’t feel comfortable? Provide resources for them. • No talking during this part of the project. • Take notes on paper. • Students must create ONE DESIGN by themselves.

17. Project 1 - Make a landfill liner Identify Alternatives: • Students take turns sharing his or her design(s). • No talking while each student is sharing. • The other team members take notes while the other students share. • Each team will have 3 designs to choose from at the end of this activity (one per team member)

18. Project 1 - Make a landfill liner Select Best Solution • Students pick the design they think will be successful. • If students disagree, they can combine designs. • If students still argue and disagree, they can choose the order for the three design choices.

19. Project 1 - Make a landfill liner Implement Solution • Build and test the “best” solution.

20. Project 1 - Make a landfill liner Evaluate Solution/ Communicate • Student teams share out their designs and their results. • Middle School students need guided questioning OR this will take forever.

21. Project 1 - Make a landfill liner Refine • Redesign and retest based on communicated results. • Can be a reflection or can be an actual retesting. Suggestion: *One variable->Share-> Redesign after sharing

22. Project 2: Overview • This unit was written for an integrated CP Math 2 class in a co-taught situation. • One teacher and one intervention specialist. • 12 students per class with IEP.

23. Project 2: Mouse Trap Cars • The main topic of this lesson is linear equations. • Students will measure distance vs. time.

24. Activity 1: Tennis ball drop • Students were required to take data of how long it took a ball to reach the ground. • Students practice determining relationships between two different quantities of variables.

25. Activity 2: Engineering Design Process • Students used the engineering design process to create a prototype of a working mouse trap car.

26. Activity 2: Constraints Materials: • 1 12in piece of wood • rubber bands • 4 cd’s • 2 axles • nuts/washers • tape • 3 mouse traps • string (arm length)

27. Group work: • Each group will be given a kit that contains the necessary materials for a mouse trap car. • Take 5-10 minutes to “tinker” with the kit. • In your group, begin filling out the EDP activity worksheet for 10 minutes.
