Inspirational Quote of the Day: “The kids who ask WHY are the ones who are going to change the world.”– Neal Thompson
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:
Warm-Up: Take 5 Warm-up
To Do List:
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
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 Friday the 19th.
