What We Did: We started to explore in the Simulation to see what happens to molecules when condensation occurs and when raindrops form.
What We Saw: Raindrops forming
What did you learn about how raindrops form?
Sentence starter: I learned raindrops form when ____________________

Freshwater and Saltwater Drops Investigation
We learned from the sim liquid water produces water vapor.
Will any body of water—even one as small as a few drops—will change into water vapor?
Let’s observe a small amount of water to find out if it turns into water vapor. In our investigation, we will test two very small bodies of water: three drops of salt water and three drops of freshwater. The papers will be left to dry overnight.
Observe paper with freshwater and saltwater drops from Lesson TES 2.3

Explain why you chose Model A or Model B to show what’s happening to the water molecules in the puddle. Use the words water and molecules in your explanation.
Sentence Starter: In Model ________________ (Choose Model A or Model B) it shows ________________________
What temperature does condensation happen at?
A) Hot (High temperature)
B) Cold (Low temperature)
Based on what you know and our new definition of evaporation, what happens to the molecules of liquid water when they evaporate?
A) They become new molecules that have spread out to become a gas
B) They are still water molecules but they are now spread out as a gas
C) They become new molecules but they are still liquid water
What phase (state) of matter is this water?
A) Gas
B) Solid
C) Liquid
What do the molecules in liquid water look like?
A)
B)
C)
What phase (state) of matter is water vapor?
A) Gas
B) Solid
C) Liquid
What do the molecules in water vapor look like?
A)
B)
C)
How did the molecules move from liquid water to water vapor?
A) The molecules moved closer together
B) The molecules moved farther apart
What happens to the temperature when water evaporates into water vapor?
The temperature increases (goes up / hotter)
The temperature decreases (goes down / colder)
What temperature does evaporation happen at?
A) Hot (High temperature)
B) Cold (Low temperature)
What is the best explanation for what is happening to the water in the puddle?
A) The water vapor is condensing and turning into liquid water
B) The liquid water is evaporating and turning into water vapor
C) The liquid water is condensing and turning into water vapor
D) The water vapor is evaporating and turning into liquid water
Which model best shows what’s happening to the water molecules in the puddle? Explain why.
