Design Step 2

NGSS Standards:

NGSS.HS-ETS1-3 Evaluate a solution to a complex real-world problem based on prioritized criteria and trade-offs that account for a range of constraints, including cost, safety, reliability, and aesthetics, as well as possible social, cultural, and environmental impacts.

DCI - ETS1. Criteria and constraints also include satisfying any requirements set by society, such as taking issues of risk mitigation into account, and they should be quantified to the extent possible and stated in such a way that one can tell if a given design meets them. (secondary to HS-PS2-3)

DCI - ETS1.B When evaluating solutions, it is important to take into account a range of constraints, including cost, safety, reliability, and aesthetics, and to consider social, cultural, and environmental impacts. (HS.ETS1-3)

DCI - ETS1.C Criteria may need to be broken down into simpler ones that can be approached systematically, and decisions about the priority of certain criteria over others (trade-offs) may be needed. (secondary to HS-PS1-6)

Learning outcomes: Students will be able to: 

• Ask and/or evaluate questions that challenge the premise(s) of an argument, the interpretation of a data set, or the suitability of a design. 

• Evaluate the merits and limitations of different models of the same proposed tool, process, mechanism, or system in order to select or revise a model that best fits the evidence or design criteria. 

• Plan and conduct an investigation individually and collaboratively to produce data to serve as the basis for evidence, and in the design: decide on types, how much, and accuracy of data needed to produce reliable measurements and consider limitations on the precision of the data (e.g., number of trials, cost, risk, time), and refine the design accordingly. 

• Consider limitations of data analysis (e.g., measurement error, sample selection) when analyzing and interpreting data. 

• Construct and revise an explanation based on valid and reliable evidence obtained from a variety of sources (including students’ own investigations, models, theories, simulations, and peer review) and the assumption that theories and laws that describe the natural world operate today as they did in the past and will continue to do so in the future.  

• Design, evaluate, and/or refine a solution to a complex real-world problem, based on scientific knowledge, student-generated sources of evidence, prioritized criteria, and trade-off considerations.

CAPSTONE PROJECT  DESIGN STEP 2 OUTLINE:

GOAL:  Generation Of Alternative concepts and technical Drawing of your ideas

Design Step 2 

1. Brainstorm on your journal and padlet to determine at least three feasible alternatives (concepts) for each function/subfunction of your product and assemble the results in a classification scheme.

2. Functionally decompose your product.

3. Form three promising design concepts by combining compatible function-subfunction alternatives/concepts from your classification scheme

4. Firm up your three design concepts by sketching them in the form of conceptual drawings and by implementing the techniques learned in the sketching tutorials. On paper and Digitally

Week 24

Monday 02 /10 to Friday 02/14(Design Step 2)

• COLLECT MATERIALS AND START BUILDING PROTOTYPES, tinker, test - SUMMARY REPORT #2 Due Friday 02/28  (FORMAL PROTOTYPE PROGRESS ASSESSMENT IN March DATE TBD)

  • Please take pictures of your team's ongoing prototyping, testing, and tinkering progress and attach them to this assignment.

  • Include a dated summary document detailing what each team member is working on (regarding prototyping). Include:

    • • 1. what worked, what did not, 

      • 2. problems encountered & and possible ways to solve them

      • 3. Eureka moments! (good & challenging)

      • 4. Next steps

• Administer the Survey, collect and analyze the results & Refine the List of design specifications (D&W list), taking into consideration your market research and survey  data (Due Friday  02/14)

• Fusion 360 Tutorial for Absolute Beginners, "Make a personalized stamp", individual, but share with your team  (Due  02/14) Use Inkscape or similar software to create your Name for the stamp (Vector format, CSV extension)

Step 2

• CAREFULLY READ the "Capstone Design Step 2: Generation of Alternative Concepts" and all the documents linked to the page, and follow all the steps. (Due Friday 02/14)

• Brainstorm on your  Journals and on Padlet, with your team, to determine at least five feasible alternatives (concepts) for each function or sub-function (ask the question "How do we do this in another way?) of your product. (MUST Consult with your mentors) (Due  Friday  02/14)

•  Functionally decompose your product.  Represent the functional decomposition by creating a  functional decomposition flow chart/ mind map (sign up using your students' Gmail at Figma.com ) and invite all team members and the teacher. (Due Friday  02/14)

•  Assemble the previously identified functions/subfunctions' and the alternative concepts/designs in a Classification Scheme. Make sure to include a written explanation of your team's thought process when completing the scheme. (Due Friday  02/14)
