TE 1.3: Temperature and Motion

Objective: KWBAT compare, contrast, and distinguish the difference between warm water and cold water on a molecular scale by investigating on the Sim.
Part 1

Part 1: Warm Up

Reflect on your knowledge from your previous lesson!
0

Predict: Why do you think molecules move fast in hot water?

Sentence Starter:
I think molecules move fast in hot water because...

0

Predict: Why do you think molecules move slow in cold water?

Sentence Starter:
I think molecules move slow in cold water because...

Let's think about liquids again. Let's say you are drinking hot tea.

Describe what happens to the temperature of the tea if you add cold milk.

Sentence Starter:
When you add cold milk to hot tea, the temperature....

Part 2: Using the Simulation

To help decide which heating system will heat Riverdale School, we need to continue to explore the difference between hot and cold things. This will allow us to understand what is happening when the air in the school gets warmer. Today you will use the Thermal Energy Simulation to investigate this more!

Open the Thermal Energy Simulation (Click to go to sim) to investigate how the sim works and what you can change.

What are some things you can do in RUN?
(what can I do in the sim as soon as I open it?)

0

What are some things you can do in ANALYZE?

1

What do you think the small circles in the sim represent?

Part 3

Part 3: Simulating Hot and Cold Water

  • Relaunch the Thermal Energy Simulation.
  • Add two same-sized samples.
  • Make one sample hotter (press the + plus) and one sample colder (press the - minus). (If working in partners, one person models the hotter sample and the other person models the colder sample.)
  • Observe the difference of the molecules in the two samples.
  • Use your observations to answer the following questions.
2

What do you notice about the movement of the molecules of the two samples?

Hint: Look at the kinetic energy of the samples!
The more yellow, the faster they are moving = hotter.

Sentence Starter:
The molecules in the hotter sample move....
The molecules in the colder sample move....

0

TRANSFER: After what you observed in the SIM, why did the food coloring spread faster in the hot water?

Hint: Think about what temperature does to water...and what that does to the movement of molecules!

Part 4

Part 4: Model of Hot and Cold

1

Which image shows the correct speed of molecules in hot and cold water?

0

Explain your answer.

Sentence Starter:
Model _____ shows the difference between the speed of hot and cold water because according to the key...

Hint: Look at the key!!

Part 5

Part 5: Exit Ticket

You are eating a hot bowl of Pozole. You stop to go complete your homework. When you return to your Pozole, it’s cold.

3

Describe the speed (fast or slow) of the molecules when you first began eating the Pozole, and describe the speed of the molecules when you returned.

Sentence Starter:
The molecules of my Pozole were _____ when I first began eating the Pozole.
When I returned....

You can answer the prompt by writing OR by drawing your answer! Do what is best for YOU.

Now, draw or describe the food you ate last night.
How were the molecules moving in your food?
Then, draw or describe the drink you had with your food last night. How were the molecules moving in your drink?
