S: Ari Star's Diary
FC: Ari Star's Diary
1: I, Ari Star, dedicate this diary to my parents, friends and every star in the whole entire universe!
2: Dear Diary, Today, all this gas and dust was pulled together with gravity into a ball. When the ball began getting closer together, it got hotter and hotter. The hydrogen changed into helium and that is called nuclear fusion. This is like a nebula. A nebula is a large cloud of dust and gas in interstellar space and it is where some stars are born and some stars explode and die. Love, Ari Star P.S. Oh. I forgot to say that all of that formed me! Today is my birthday! It's my first day as a star!
4: Dear Diary, I am now in my "Main Sequence Stage". Well, that's what my mom told me today. She said it's the second stage of my life and that it's the longest stage of my life. She told me that right now, as we speak, energy is being produced in my core when the "hydrogen atoms fuse into helium atoms". Whatever that means. Mom says that I am making a lot of energy and releasing it into space. She says I am not going to grow very much during this stage (that stinks) but at least I won't be shrinking either, since my size isn't supposed to be changing very much! But that only happens if I have a continuous supply of hydrogen atoms to become one with the helium atoms. Love, Ari Star
6: This is me as a Red Giant star! | My new baby brother! | <-
7: Dear Diary, I grew the other day or I should say "expanded and cooled" (the scientific version of me turning into a Red Giant star)! I am now a Red Giant. I am about 10 times larger than the sun! Isn't that something to be proud about? But, I'm not as big as my friend Sunny Star because she is a Supergiant, about 100 times bigger than the sun! We have entered the third stage of our life. A Red Giant is a star that grows bigger and cools once it uses all of its hydrogen. Love, Ari Star P.S. I got a new baby brother! Isn't he adorable?
9: Dear Diary, I entered the final stage of my life. I am becoming a white dwarf because I was about the same size as the sun. A white dwarf is the small, hot, dim star that is the leftover center of an old star. I have no hydrogen left so I can't make energy by fusing hydrogen atoms into helium atoms. I am going to shine for a billion more years before I completely cool. That is not barely anytime at all! NOOOO! My life is ending! Love, Ari Star
10: I would like to thank my text book called Astronomy, which gave me all of the information I needed for this diary. I would also like to thank Google Images for my pictures.

14: Author's Note/Reflection Overall, I really liked this project. I liked it because I was able to use my imagination to help myself learn about a star. I was able to combine that with humor and creativity to help write my diary as a star's point of view. This project was a tiny bit difficult because all of the information in my text book was in third person and I needed to write my diary in first person. I was able to make this project really interesting by putting in unrealistic pictures along with scientific pictures and I was able to put in cool "sticker" things. I hope you really enjoy this diary of a star. Sincerely, Arielle Goldberg (also known as Ari Star!)
