Thank you Lauren, and she is not mean she is right. This is meant to help you with science. As far as why the sun is so far from the earth... that is how God has made it. He made the planets and designed each with their own gravitational pull and other properties that maintain the spacial distance. It is just because God made it that way!

Lauren, The test is a week from this Thursday (so it will be the 1st of April 2010) as for your project...
Steps
1
Fill a bottle with just enough warm water to cover the bottom.

2
Get a match and let it burn for a few seconds. Blow the match out and immediately place the head of the match into the bottle. Let the smoke from the match fill the bottle. After a few seconds, the smoke will seem to disappear.

3
Slowly screw the cap onto the bottle. Do not squeeze the sides before the bottle is tightly capped, you do not want any of the smoke or air to escape.

4
Squeeze the sides of the bottle hard. Do this three or four times. Then wait a few seconds, and squeeze the bottle again, but hold the squeeze for a few seconds and quickly release the squeeze.

5
Look at the formation of fog in the bottle. You should see your very own cloud there!

Here is another option (note they are both pretty much the same).

To make your cloud in a bottle, follow the easy steps below.
WARNING Young children are cautioned NOT to do this experiment unsupervised!

Difficulty: Easy
Time Required: Under 10 minutes
Here's How:

1. Remove the label from your cloud bottle and rinse it thoroughly. Do not use soap and do not dry the inside.

2. Add a small amount of very warm water to your cloud bottle. Replace the cap and shake it up so that water droplets are sticking to the inside of the bottle. Pour out the excess water.

3. Carefully light a match and drop it into the bottle. Shake it up so the match burns out. The smoke adds one of the key ingredients for cloud formation dust.

4. Immediately replace the cap and shake it back and forth 2-3 times. You now have the second ingredient water.

5. Using both hands, squeeze the center of your cloud bottle as hard as you can. Then, release both hands evenly and very quickly. You are now simulating the third ingredient temperature and pressure changes.

6. After several squeezes you should see a cloud that appears when you release your hands. If you don't see a cloud, try placing the bottle near a dark background for contrast.

Tips:
1.Explanation: How does a cloud form?

2.For younger children: Smaller children can use a 16 oz. soda bottle. Adults will find a 2 liter bottle easier to observe.

3.Advanced: Use a bicycle pump to change the pressure and see even more clouds.

4.Going further: Try using other sizes of dust particles. Design an experiment to determine the best size of dust particles to use. You could also test different water temperatures.

What You Need:
•A clear plastic bottle with a screw on cap
•Matches
•Warm water

Let me know! I am sorry I did not respond sooner.

Lauren,

I am sorry I did not understand "it find that u respond late"? Let me know

Nicholas, why is what blue? the sky? A clear cloudless day-time sky is blue because molecules in the air scatter blue light from the sun more than they scatter red light. Blue has a shorter wavelength (and smaller waves) so when it collides with the oxygen and nitrogen in our atmosphere it is scattered more than other colors. Violet also has a short wavelength, but our eyes are more sensitive to the color blue (that is more than violet), so we perceive it to be blue. When we look towards the sun at sunset, we see red and orange colors because the blue light has been scattered out and away from the line of sight.

Mrs James, stars that are hot did they they start cold? And if we were at a distance would the sun look like: a circle, or a regular star?

Elam, stars are hot. When they form it is a reaction that produces a lot of heat so I would say that all stars are hot even when they start. As for the sun, most stars are somewhat circular in shape and the only reason we see what may appear like points is because of the way the light is diffracted/distributed in our eyes. I am not sure about the sun though. Although I would think that the further away it is the more likely it would be to appear to have the points we have grown accustom to drawing.
