What Is the Design Process? PBS Learning http://www.pbslearningmedia.org/resource/phy03.sci.engin.design.desprocess/what-is-the-designprocess/ Engineering Design Process 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. 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. 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) 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. Project 1 - Make a landfill liner Implement Solution ● Build and test the “best” solution. 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. 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 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. Project 2: Mouse Trap Cars ● The main topic of this lesson is linear equations. ● Students will measure distance vs. time. 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. Activity 2: Engineering Design Process ● Students used the engineering design process to create a prototype of a working mouse trap car. 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) 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.
