TOTAL TIME: 3 Hours
OBJECTIVES: To investigate and learn about the design process
To design some pumps and wind systems
This session is to be used only if the participants are going to do actual design work.
MATERIALS: Model materials & supplies, wood, wire, glue, pins, construction paper, etc.
Blackboard or equivalent
Step 1: 5 minutes
Review and clarify the objectives of the session.
Step 2: 1 hour
Examine and expand on the design process using examples. Give design process sequence, outline and procedure.
Step 3: 5 minutes
Form design and construction groups. Explain that these groups will actually construct what they design.
Step 4: 2 hours
Have the groups design the wind system that they are going to build.
Note at the beginning and the close of the session that presentation of designs will be the following morning.
RESOURCES: Copies of Attachment 13-A

THE DESIGN PROCESS
I. Overview of the Whole Design Process
II. A Closer Look at the Design Part
• Be specific, for example:
• It must be buildable in 20 hours.
• It must weigh less than 25 pounds.
• It must use only wood.
• It must be built only with hand tools.
• It must be usable by both sexes, etc.
