Temperature, Thermal Energy, & Heat
"There is no energy crisis, food crisis, or environmental crisis. There is only a crisis of ignorance!" (Buckminster Fuller, R. 1981).
Connections
nnBefore continuing in this section, Kinetic Molecular Theory, lets make some CONNECTIONS to the knowledge you already have stored in your information processor (your brain).
Using your understanding of the words temperature, thermal energy, and heat provide a definition of each with specific examples.
You may wish to use the following questions to guide you through the brainstorming process:
You may wish to use the following questions to guide you through the brainstorming process:
Now, if you heard the following expressions “it is freezing in this classroom,” “ouch, this coffee is too hot,” or “it feels warm outside” how would you classify them? As expressions of temperature, thermal energy, or heat?
Using the expressions above, describe what would happen to the speed of the energy of the molecules in an ice cube sealed in a flattened ziploc bag (the air has been squeezed out), if it were slowly heated by a hair dryer. What causes the ice to melt? What causes the water to evaporate? Does the volume and the density of the molecules change?
Take the time to brainstorm your own ideas on the Google Document, Energy Transfer – Temperature, Thermal Energy, & Heat – Individual Thoughts, that was pushed to you through Doctopus. Afterwards join the discussion in the class discussion forum, Energy Transfer – Temperature, Thermal Energy, & Heat – Connections.
Work together to generate as many descriptions as possible.

You may wish to use the following questions to guide you through the brainstorming process:
- What you hear the word "energy" what do you think?
- What term do you use to describe the climate conditions of the environment you are in?
- How is temperature different than heat?
