Design a Carrying Device for People Using Crutches

To share with the entire class:

• computers with Internet access and Microsoft PowerPoint software
• pencils and paper or notebook
• measuring rulers or tape measures
• materials and fasteners for device fabrication, such as various woods, plastics, metals, cardboard and fabric, string, rope, nails and screws, nuts and bolts, staples, clamps, Velcro, zip ties, etc., as specified by the student groups*
• tools for cutting, shaping, forming, joining, fabricating, assembling and finishing designs, such power/hand saws and drills, hammers, screwdrivers, drills, duct tape, glue suitable for the materials, sewing machine or needles and thread, etc.
• scale, for measuring weight up to ~5 pounds
• pair of crutches, one per group (if enough available)
• safety glasses, at least one pair per group, depending upon tools used
• ear protection, can be shared among groups, depending upon tools used
• Engineering Design Process Pre-Activity Test (PDF), one per person
• Steps of the Engineering Design Process Visual Aid (PDF) (as a PowerPoint slide or handout)
• Project Design Criteria (PDF)(as a PowerPoint slide or handout)
• Assistive Device Project Research Handout (PDF), one per person
• Materials Properties Research Handout (PDF), one per person
• Engineering Design Process Post-Activity Test (PDF), one per person

* Note: For this project, students generate their own list of materials (and tools) and are given no restrictions on the type of materials they choose for their designs other than meeting the project constraints for weight and safety, which naturally serve to minimize the size and amount of materials necessary for the activity. Optional idea: Invite students to bring in their own materials to supplement the teacher-provided materials. Be sure to specify whether it is permitted for students/parents to buy materials or limit their contributions to recycled materials.
