View Slides: 1.5.5. BID WOW!
- What could have inspired the change from the ice climbing ax on the left to the ice climbing ax on the right (see images on slide 2)?
- What organisms in nature do similar things to an ice climbing axe?
Class Discussion: on what students think.

You will complete the 1.5.5. Conceptual Design 3: Initial Prototype handout, which has 4 parts - Evaluate conceptual designs in EDPL, Sketch Initial Prototype, Plan for materials, and a check to make sure you have integrated what you have learned into your design.
Teacher Note: It may be helpful to show this video on how to make a cardboard prototype to students.

Part 0:
- Review the information you have learned throughout the unit, along with your previous conceptual designs.
- Work in your group to evaluate your conceptual designs in the EDPL “evaluate” tab.
- Choose if a design is likely/unlikely to fulfill a requirement and give a reflection (or explanation) on your choice.
Part 1:
- Sketch the plan for your initial prototype. This sketch will be detailed, and include dimensions (Width x Length x Height) and labels for each portion of their system.
- If needed, add specific details of “zoomed in” subsystems.
Part 2:
- Work together to identify materials needed to complete your prototype, and create a plan for gathering the materials needed to build your design.
Teacher Note: Remind students that they should use simple, readily available materials (paper, cardboard, old fabric samples, tape, glue,etc.) They will need to bring in these materials to the next class.
Part 3: Check
- Did your group integrate what you have learned about existing solutions, inspiration from biological systems, and heat transfer to this prototype?
EDPL
Upload images of your prototype 1 and conceptual design into the “Ideate” section of the EDPL, if your group made changes to your design from conceptual design 3.
