Have you ever wondered how roller coasters work? Well I have, Today we will learn the answer together.

What keeps a roller coaster on the track? 
The train's nylon or polyurethane wheels move on the top, bottom, and side of the tube, holding the train to the track while it travels through loops and twists. Doesn't that make you wonder how do roller coasters accelerate? We will learn that in just a min. All right! you have been waiting long enough.

How do roller coasters accelerate? 
Well, Its kind of simple. After a long steep hill-like rail down, there is normally a long straight line before the end. That line gives it time to slow down. That's how roller coasters accelerate.

That is what we learned about how roller coasters work, I hope we can learn more soon

Do you have a best friend? Best friends are the best! I have a best friend at school. Her name is Katelyn. We have been best friends since second grade.

Best friends like to play games. We like to play hide and seek in recess. Our favorite thing to do at the playground was going on the swings.

Best friends like to read books to each other. In second grade me and my best friend would read in the morning. Our favorite book is Pete the Cat.

Having a best friend cheers you up when you are sad because they make you happy. Katelyn would help me feel better when I got hurt. I helped Katelyn too.

In conclusion, my friend is fun because she is the best. I miss Katelyn and I hope we can see each other in 4th grade.

The earth is where we live. The earth has oxygen so we can breathe and the moon does not. The earth is full of life. The earth has food as water and everything you need to survive. The moon is where gravity is zero. One interesting thing is every year the moon gets 1.5 inches away from the earth

Also do you wonder what the light in the night sky is? It's the moon! The moon floats around the earth like how we float around the sun. Three moons can fit inside earth. Earths water is actually very low it may seem like there's a lot of water on earth but most of it is just salt water. 

Finally, there is a lot of land on earth even though most of it is full of spiders, humans, cows and other things. The moon is very rough because the gravitational pull of earth takes chunks of the moon and pull it to earth. That's why people can't live on the moon or they would float.

In conclusion, the moon and the earth are very interesting.
