For Kids, About Weather: Rain Facts!

Learn all about rain! Where does rain come from? How does water evaporate? Do these fun experiments to make some rain!

We will never have any more water in our world. All the water we now have is all we will ever have, but that is okay. The water that is in our lakes, rivers, oceans, seas, and even our swimming pools, will "evaporate." That means it will rise up into the sky.

We can't see it when it does this. When it goes into the sky, it makes the clouds. The clouds move. They may move over another part of the land. Finally, they will be so full of water they will need to let some of it go. So, to let the water go, they rain.

The water in the clouds comes down on us. It hits the ground and some soaks into the dirt. Some runs back into the rivers, lakes, oceans, seas, and even our swimming pools. Some of the rain soaks deep into the dirt, way down into the earth.

We use wells to bring that water back up, so we can use it. It is the water that comes from out of the pipes in our house. We use it, and then it goes down the drain.

From the drain, it goes into our septic tank deep in our yard, or into the sewer. From the septic tank, it soaks back into the ground. If it is in the sewer, it will come out somewhere, like the ocean or a sewage pond.

Then it will evaporate again, and it will fill up the clouds again. When the clouds are full, it will rain again.

Rain water is clean and pure. As it soaks into the ground or is evaporated, it is cleaned by the ground or the air.

So, you see, we use the same water over and over again! The water is being "recycled" in a very natural way!

TWO WAYS TO MAKE SOME RAIN

RAIN-MAKING EXPERIMENT NUMBER 1

If you want to make some rain, here is what you do:

1. Fill a glass about half full of water.

2. Cover the glass tightly with some plastic wrap.

3. Put a rubber band around the glass to hold the wrap in place. Make sure there are no holes in the wrap over the top of the glass.

4. Put the glass of water in the refrigerator.

5. Wait one or two hours and check the glass. When you see water droplets on the inside of the glass on the plastic, you know your experiment is working.

The longer you wait, the more water droplets will form. You can even wait until the next day.



6. When you see plenty of droplets, take the glass out of the refrigerator and set it on the table or counter, or some other place where it won't be in the way.

The water has evaporated up to the top of the glass where the plastic is. The plastic is kind of like clouds. Pretty soon, as the glass begins to warm up, the plastic will have more water than it can hold onto, and the drops will rain back into the glass.

YOU JUST MADE RAIN!

RAIN-MAKING EXPERIMENT NUMBER 2

Here is another way to make rain. This works very quickly, but YOU WILL NEED AN ADULT OR BIGGER PERSON TO HELP YOU.

1. Take a glass measuring cup and put 6 to 8 ounces of hot water into it.

Do not use a regular drinking glass, because it may break. The water needs to be very hot. Near boiling is best.

2. Cover the measuring cup with plastic wrap.

3. Put a rubber band around the cup to hold the plastic in place. Make sure there are no holes in the wrap covering the top of the cup.

4. Set the measuring cup where it won't be in the way. The plastic may bulge up a little.

In about five minutes, you will see water droplets on the inside of the cup on the plastic.

5. Put the cup in the refrigerator and wait a few minutes. Take the cup out and you will see the droplets begin to fall from the plastic back into the cup. You might want to tap the plastic to make the droplets fall.

MAKE WATER EVAPORATE

If you want to see how evaporation works, do this:

1. Fill a glass with water. It helps if you can see through the glass.

2. Take a marker and mark the outside of the glass, just at the top of the water.

3. Set the glass on the table or counter, or some other place where it won't be in the way.

4. Now, let the water stay there for a day or two.

5. Each day, check where the top of the water is. You might want to make a marker line each day. You will see that the water goes lower and lower each day. Where did it go? It evaporated into the air. It is now helping to make a full cloud. The water you put into the glass will fall as rain. Somewhere in the world, your water will splash down on the ground, into a lake or river, or maybe onto a person!
