Intraocular Pressure Sensor Design Challenge

Each group needs:

• graph paper and pencils
• access to a computer or laptop with Internet access
• tinkercad 3D design tool, a free and easy-to-learn online app available at https://www.tinkercad.com/; requires an email address to open a free account; must be 13 years of age or older
• Overcoming Glaucoma: Dennis Howard's Story Handout (PDF), one per person
• Under Pressure WebQuest Worksheet (PDF), one per person
• homework from the associated lesson; these are students' own designs for pressure sensor devices that measure eye pressure for people with glaucoma in the form of graph paper sketches with labeled components and structures (RFID reader, RFID tag, antenna), including brief function descriptions, one per person
• Peer Evaluation: Evaluating Preliminary Designs Checklist (PDF), one per person
• Peer Evaluation: THE TEST? Will It Fit? (PDF), one per group
• Teacher Evaluation: Under Pressure Prototype Presentation Grading Rubric (PDF), one per group
• Peer Evaluation: Potential Projects to Fund Analysis (PDF), one per person
• presentation method or materials, such as PowerPoint®, Prezi and/or poster board

To share with the entire class:

• 3D printer; alternatively, if 3D printing is not available, use modeling clay
• 1 spool of 3D printer filament, such as FLASHFORGE PLA filament for $29 at https://flashforge-usa.com/products/pla-filament-for-creator-and-creator-pro?variant=5344971456550; 1 spool of filament makes ~140 prototype devices based on the design constraints within this activity
