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). o 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.
