Optional marketing presentation

16.A Communicate and present information orally about the proposed performance of a protective device, explaining how specific structures and materials have been manipulated to reduce peak forces in a collision.

• Listen for students to demonstrate understanding of ideas of performance expectations that were not fully met at the end of Lesson 15.
• Students should list trade-offs and the reasoning behind those trade-offs to optimize their design solution.
• Listen for the rationale for decisions that led to the optimization of the design.
• Listen for students to include a rationale for their material choice that involves the properties of their material that help reduce peak forces during a collision, such as the ability of materials to deform, space for air, and distribution of contact forces over a greater surface area.
• See Potential Accompanying Standards for details on additional standards to assess, if wanted.

This is the second and additional time to assess the understanding of material properties, shapes, and structures that reduce peak forces in a collision. If students do not include this, ask students during the question and answer section of the presentation why they have chosen those specific materials and what they do to reduce peak force. This presentation provides an additional opportunity to check in on these ideas, and this additional assessment opportunity may not be needed for all students.

Give feedback. As the presentation is conducted, remind the stakeholders and/or investors to use Investor Design Feedback Form to give feedback on the design. At the end of the presentation, provide 2-3 minutes for stakeholders to ask questions and give feedback to each student.
