ozone and ozone depletion
Ozone or O3 is three oxygen atoms. Its like protctive shild aginst uvratiation. the ozone is located in the stratosphere. some of the ozone is in the troposphere witch is bad for breathing in.
how ozone depletion is where the green house effect is getting stronger witch makes the ozone start to deplet. carbon dioxide makes the green haous effect to warm up more then normal. this problem wouldn't happen if there where more forests, because plants take carbon dioxide and turn it into oxygen.

The issues are that acid rain affects lades, trees, and wild life. Causes are bruning coal. Witch makes sulfer oxides. Nitrogen oxides and sulfer oxides combind with water makes nitric acid and sulfuric acid. Some conqences are damaged buildings and statues, and kills or harms plants, ampfibions, fish, and insects. A solution could be not to burn coal.

atmospheres
The atmosphere of the earth is very different from the moon's. The moon has a very little atmosphere. But when a asteroid comes to earth it burns up before hitting earth unlike the moon. Other planets have atmosphere but but humans can't live there. Because there are gas planets.

Zoom
The book "Zoom"is about going fron one thing to another. The thing that it starts with is the top of a chicken's haed and goes all the way to the earth from far away. It is amazing on how you don't even expect the next to the other
Precpictive is a skill sicentist use to study the natural world. It also helps sicentist study the stars and skys. Also how our bodies work. The book "Zoom"is a graet example of precpictive.
There are many things in the field of Science and one of them are Astronomy. Astronomy is where astronomers study stars, space, and many other things. The most common thing that astronomers study is our solar system.

Enigma Box
The skills scientists use are observation, inferring, predicting, and classifying. This skills help scientists study the world. The skills where used to help me figure out the enigma box. The enigma box is a puzzle. I had to use observation and inference to find out how it worked.
The observations I made where that nothing happened until 470ml. where poured in that the water came out. When 100ml. was was poured nothing happened. At 200ml. little drops started to come out. At 300ml. the drops came more quick. I couldn't under stand how or why it did that so I had to make an inference.
The inference I made was that when it reached a level it would let all the water out. Or it was like a trick glass was inside of it and wouldn't pour out until it got to the top. Maybe there is a little man in there and lets the water out when ever he wants.
The enigma box was puzzling, but I finally found out how it worked. My guess wasn't correct. i guessed it was like a trick glass. It would fill up until it got to the top and then it would let the water out. I was right about one thing, that when it was full it would lit the water out. There was a curved straw in there, so when the water went above the straw it would let the water out.
