Announcement-Science Olympiad is looking for some new competitors.- Application

Objective: 7.2 Lesson 2- How do heaters get warm without a flame? 

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: 

• • Circle of Trust- Pick a norm.

  • Today's Vocab Escape Room Race Starting Line

  • Take 5 Warm- up

Pumpkin Observations

Copper Crystal Observations ( See Schoology )

Pop Quiz- You will get full credit for completing this quiz. I want to see how effective the lesson was on Wednesday.

To Do List: 

1. Navigation Ingredients 

2. Prepare for Flameless heater and hand warmer investigations

Data Sheet is in Schoology

3 Plan and carry out the flameless heater investigation as a class Video Link

4. Carry out the hand warmer investigation in small groups, Video Link

5 Have a building understandings discussion about our results

6. Have a building understandings discussion about our results

7. Navigation Consider based on this lesson's work what we should investigate next time.- We want to test different chemical reactions to determine if any of them cause an increase in temperature for use in our homemade flameless heater designs. Once we identify a reaction with which to move forward, we will investigate energy transfer from that system to the food system using an Energy Transfer Model.
