Inspirational Quote of the Day: “The beautiful thing about learning is that no one can take it away from you.”– B.B. King 

Objective:  

7.2 Lesson 3 What other chemical reactions could we use to heat up food?

In this lesson, we test different chemical reactions to determine if any of them cause an increase in temperature for use in our homemade flameless heater designs. We figure out that root killer and aluminum foil cause the largest increase in temperature, and we think it may work to heat up our homemade flameless heater. We model the chemical reaction as particles and the transfer of energy out of the reaction system to the food system and investigate varying the weight of each system. 

Objective:  

7.2 Lesson 4 How much of each reactant should we include in 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 1 Explore and Molecular View- FeeltheHeatSE




1. NAVIGATION

2. PLAN FOR PROPORTION OF REACTANTS INVESTIGATION

Discuss the amounts of reactants to test and what data to collect. Evaluate and discuss the investigation procedure.

3.CONDUCT PROPORTION OF REACTANTS INVESTIGATION

Different groups test different proportions of reactants and record data in their science notebooks.


4. REFLECT ON TYPES OF INSTRUCTIONS

Conduct an exit ticket about what makes good instructions.





Check for Understanding: Reflect on Norms

Circle of Trust

Norm Focused Reflection


We plan and conduct an investigation to determine which proportion of reactants will work best to heat up our food. Then, we reflect on what makes good instructions and identify our stakeholders. Finally, we administer a survey to our potential stakeholders to figure out what aspects they find most important. 


Homework: Flameless Heater Stakeholder Survey  Please interview family and friends about creating a homemade flameless heater to heat food during an emergency. Initials of the people interviewed please submit to Schoology. Due Tuesday the 23
