THE WATER IS QUICKER THAN THE EYE

Things I learned from

books about water:

How high in the sky can water go?

Clouds are water vapor. The

highest a cloud goes is 9 miles

above earth.

How do you get water vapor?

Water vapor forms when liquid water turns into gas.

What makes water evaporate?

Evaporation is caused by heat.

Where do the most clouds form?

Near the equator will be the most clouds because• The sun makes it hotter• Because it is hotter, more water evaporates• Since more water evaporates you get more clouds.

How do you get condensation?

Condensation happens when air cools down.

How do you get clouds?

Condensation makes clouds because the water droplets cluster together.

Can the air hold a whole bunch of water?

When the air is 18F warmer the air can hold two times more water.

Things I know about water:

Water evaporates, condenses

and precipitates.

Water evaporates slowly.

Small bits of water evaporate.

Little bits of water turn into

clouds.

Little bits of water stick together and that’s how clouds are formed.

Little bits come together and get so big and heavy that they fall.

When they fall, we call it precipitate.

Then the process starts all over again.

Raindrops always start as snowflakes because it is so cold up where the clouds are.

As the snowflakes fall they go through warmer air and melt into raindrops.

Snow melts.

Water makes puddles, streams, oceans, rivers and lakes.

Question:

How fast does water evaporate when there are different temperatures?

Hypothesis:

Water at higher temperatures will evaporate faster.

EXPERIMENTThis experiment will measure how much water evaporates. A scale will be used

to measure how much water the cup has lost.

Materials:5 Cups5 Thermometers 1 Scale1 Measuring cup Water

1. Get 5 cups. Put 150 ml water in each.2. Weigh each cup.3. Put cups of water in certain places

1 – near woodstove1 – in freezer1 – in refrigerator1- in bedroom1- in kitchen

4. Wait a day, weigh each cup and see how much water each lost. Weigh the cup on a scale. Write down the surrounding temperature.

5. The next day, weigh each cup and see how much it lost.6. Do step 5 for 14 days.

Results from first

test – weights

Results from first test-

temperatures

Results from second test –

weights

Results from second test - temperatures

Conclusion:

In the first test my hypothesis was right. In the second test my hypothesis was right. If you have a higher heat, you lose more water.

We can’t have the woodstove room data because when I wrote down the temperatures from it they were cold. When I left and did my other temperatures the heat went up in the woodstove room because my daddy started the fire. So the temperatures went up when the fire heated up and the heat went down when the fire went out.

ACKNOWLEDGEMENTS

Michele Diggins helped me by reading some of the resources to me and writing down things I said to write. She also helped by suggesting to weigh the cups with water to know how much water was lost and by saying to get a thermometer to see how hot the room was. She figured out how to make a graph on the computer and then showed me.
