Teacher Answers

Estimated class Time:

One 40-minute class period


How is heat produced?


  • CER videos (found in resource file)
  • CER organizer
  • Post-It Notes

Lesson Level Learning Objectives:

  • Science and Engineering Practice 7 Engaging in Argument from Evidence


  • The lesson will start with the students discussing how heat is produced and the positive and negative consequences of items that produce heat. Then in small groups the students complete the CER and then discuss as a class.  The lesson concludes with a discussion about what students already know about chemical reactions and what they still need to know to make chemical reactions a viable solution to produce heat for the incubators. This discussion will lead to questions to add to the DQB.

What we Figured Out: 

  • Heat can be generated in a variety of ways.
  • Chemical reactions can generate heat.

Questions we still have:

  • What is a chemical reaction?
  • Are all chemical reactions the same?
  • Do they all produce heat?
  • What are the products?
  • Are they safe?
  • How do they happen?
  • What is heat?
