Part 1: Warm Up
Last time, we reviewed a model looking at the speed of molecules in hot and cold things. Today we will learn how this connects with a more complete definition of temperature!

Reflect: Are molecules in warm water moving faster or slower than molecules in cool water? What makes you think that?
I think molecules in warm water move (faster / slower) than molecules in cool water because
Molecules move really fast in ice cold lemonade.
Explain if this is true or false.
Sentence starter:
This is (true/false) because....

Find a quote that answers this question.
What is temperature?
When an object's molecules move at a faster speed, the object has a temperature.
When an object's molecules move at a slower speed, the object has a temperature.
