FC: My Star Diary By Sun
1: I dedicate this to my family(My dad, mom, Hanna), friends, and teachers, because i admire them.
2: Nebula Star Ahh. It feels really good to think that I am going to be an amazing star soon. I was made of clouds of dust and gas called nebulae. Well, except some rare ones are formed when two stars or brown dwarfs crash together, they form a large star. It's really rare to happen. There are two different origins of nebulae. One way is to be made from the Universe, (which means that you are made of atoms and other things), or you could be produced by the supernocas of exploding stars. I really thank those supernovas, who produced me. Without them, I wouldn't have been here!
3: Main Sequence Star I am no longer in the Nebula stage now. I am now considered as the main-sequence star! This is the longest life stage I will have to go through, before I die. My energy is produced in the core. the energy is made when the H atoms fuse to become He atoms. That produces A LOT of energy. While I am in this stage, I won't be much different in size, as long as I have enough supply of hydrogen atoms. If the H(hydrogen atoms) runs out, it will change my type.
4: Red Giant I am now a Red giant. It took me So long for me to be a Red Giant, because almost all of the hydrogen atoms inside of my core have fused into Helium atoms. Without hydrogen aroms as my source of fuel, my core deals under the force of the stars' gravity. My cre's temperature increases when that happens. my shell of gas then expands and cools. The increased temperature causes the mainly Helium atoms left in charge to chane into carbon atoms.
5: White Dwarf I am very sad. I never thought that this moment would come, but unfortunately, it did. I am a White Dwarf now! Only a little bit of helium atoms, or hydrogen atoms were available, so I changed into a White Dwarf. Gravity causes my core to collapse inwards. This is not a good thing. White Dwarf equals DEATH! My temperature is VERY hot. It's like I have a high fever. I am dim in brightness, since my size decreased. Even though I an shine for billion years more before I cool fully, I am still sad. I am only a lonely core now. No one will remember me!
6: Now I am dead! This is the end of me. I am really sad, but I am looking forward to give my materials to other newborn stars. I hope that my remnants grow to be amazing stars... This is the end.... OF ME!

8: Extra Credit I've learned a lot throughout this project. I thought that I really enjoyed doing this, because this project gave me a reason to study about stars and research more about them. Even though I had to do this over break, I still had fun with it and learned a lot about both stars and Mixbook. I realized that every other creatures or things that are alive are exactly like us humans. They start by being little like a baby, then they grow to be something great. Learning about the stars was pretty interesting, since they were like us humans. I hope that we get to do another project like this.
