Inspirational Quote of the Day: “Your attitude, not your aptitude, will determine your altitude.”– Zig Ziglar 

Objective:7.2 Lesson 5 How can we refine our criteria and constraints?  

Standards:

MS-PS1-6:

Undertake a design project to construct, test, and modify a device that either releases or absorbs thermal energy by chemical processes.

MS-ETS1-2:

Evaluate competing design solutions using a systematic process to determine how well they meet the criteria and constraints of the problem.

MS-ETS1-3:

Analyze data from tests to determine similarities and differences among several design solutions to identify the best characteristics of each that can be combined into a new solution to better meet the criteria for success.

MS-ETS1-4:

Develop a model to generate data for iterative testing and modification of a proposed object, tool, or process such that an optimal design can be achieved.

Warm-Up: Take 5 Warm-up

To Do List:

Day 2 Test Powders FeeltheHeatSE

1.NAVIGATION

Reflect on the Stakeholder Survey conducted in Lesson 4 and consider what else we need to know to inform our designs.

2. OBTAIN INFORMATION ABOUT FOOD TEMPERATURE FROM VARIOUS SOURCES

Obtain and discuss food temperature information from readings to narrow down a target temperature range for their designs.

3. DEFINE A TARGET FOOD TEMPERATURE RANGE

Use existing data to discuss and define a target food temperature range for our designs.

4. REVISE INITIAL CRITERIA AND CONSTRAINTS CHART

Remain in Engineers Circle to use the information collected about food temperature to revise and reorganize the Criteria and Constraints chart to keep track of our optimal design features.

5. ORGANIZE THE CLASS-LEVEL WHAT WE DO AS ENGINEERS BOARD

Update our Progress Tracker, reflect on what we have done so far, and organize the class-level What We Do as Engineers board.

6. NAVIGATION

Think about what steps to take next in order to efficiently plan and revise our homemade heater designs.

Check for Understanding:In this lesson, we review the Stakeholder Survey results and decide we need to figure out what temperature we want our food to reach. We analyze readings about food temperatures to revise our criteria and constraints. We also determine the optimal solution for our homemade flameless heater, including total cost and mass for our homemade flameless heater design. We reorganize and refine our What We Do as Engineers board to reveal the cyclical process of engineering design.
