What is evaporation?

The process of water turning into a gas

100
What are two things that will help evaporation happen more quickly?
A warm area, and an open area
100

What represented the "load" or "weight" in our activity?

the nickel

100

What is the purpose of a waterwheel?

To do work without using people or fossil fuels

100

When water freezes, it...

Expands or takes up more room

200

What is condensation?

The process of water vapor turning back into a liquid

200
A graduated cylinder and a bowl are both filled with 50 ml of water and placed under a lamp. Which will evaporate fastest? Why?
The bowl, because it has more surface area.
200

The moving water in our lab is what type of energy?

kinetic

200

Where does the waterwheel get its energy from?

moving water

200

When water heats, it...

Contracts, or takes up less room

300

When water vapor rises into the air outside, it cools. Those drops collect to form what?

Clouds

300
In our paper towel experiment, why did the paper towel inside the closed container not dry out?
Because the water could not evaporate- it was trapped inside the cup
300

When did our wheel work the worst?

when there was only 2 fins on it.

300

What are the 3 main parts of a water wheel?

moving water, buckets, gears

300

What are the three states of matter that water comes in, and what is an example of each?

Liquid (rain), solid (ice), and gas (water vapor)

400
What is precipitation?
Water coming from the sky- can be rain, snow, hail...
400
Define surface area
The part of a liquid touching the air
400

Why is it best to curl up the fins?

they catch more water thereby making the wheel turn faster

400

What is an example of something real-life waterwheels provide for us?

Electricity/power

400

Water power is also called...

hydro-power

500
Starting with evaporation, list all the steps of the water cycle in order
Evaporation, condensation (clouds form!), precipitation
500
What is water vapor?
The gas form of water- when liquid water heats and turns into a gas
500

The fins in our lab represent what part of a real water wheel?

buckets

500

What did you have to do to make your waterwheel turn faster?

add more fins, pour water more forcefully, or "cup" the fins by bending them up.

500

What did the skewers represent in our lab?

gears
