Inspirational Quote of the Day: “I have not failed. I’ve just found 10,000 ways that won’t work.”– Thomas Alva Edison 

Objective:7.2 Lesson 6 How can we redesign our homemade flameless heater? 

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 3 Create a Device FeeltheHeatSE

1 REVISIT OUR WHAT WE DO AS ENGINEERS BOARD AND PROGRESS TRACKERS

Review Progress Tracker entries from last time to navigate into today’s work.

2 PARTICIPATE IN A WHOLE-GROUP DISCUSSION ABOUT INFORMATION WE STILL NEED

Revisit our Ideas for Investigations chart to guide a discussion about the packaging materials we can use.

3 PREPARE FOR TEAMWORK AND REDESIGN OF HEATERS

Review expectations for teamwork and plan for the different types of models that teams will use in their redesigns.

4 WORK IN TEAMS TO MODEL OUR REDESIGN ON PAPER

Consider available packaging materials and work together in teams to model their designs, including cost, mass, amount of reactants to use, assembly instructions, and how energy will be transferred throughout the device.
