Suns and Stars

Hello I am back and I am going to tell you about suns and stars. Do you now what suns and stars are? TOO BAD! I am going to tell you how they shine, how they change over time, and how scientist classify stars.

Nuclear Fusion


 The hotter something is, the more atoms move. When the atoms move they crash into each other. If atoms move quick enough they could stick together. This is called nuclear fusion. This nuclear fusion sends out lots of energy. This energy helps stars live. 

Why stars shine?

First of all a star is large ball of gas that is held together by the gravity in space. A stars core can reach millions degrees celsius. When the energy leaves a star's core it goes through the star and spreads or shines in space.

Inside of the sun

There are 6 parts of a sun. The Sun has a huge magnetic field. It is about 10 times bigger than ours. The magnetic field is not a part of the layers. Whenever a star is formed all stars are filled with hydrogen and helium in their cores. The layers of the sun are the Corona, Chromosphere, Photosphere, Core, Radiative zone, and the Convection zone. The Corona is the part of the sun when we see a solar eclipse.

How do scientists classify stars?

Some scientists classify stars on their temperature, color, and mass.   Did you know that the a red sun is the coolest star? The white and blue stars are the hottest stars.  The white and blue stars have the most mass because they are bigger. 

How does the sun change over time?

Lots of things can happen to the sun in a short amount of time. Some suns can have sunspots or solar flares. Sunspots are dark spots on the sun caused by its huge magnetic field. Also a star can get bigger and bigger until it reaches earth and then implodes.

Science Fair!!!!!!!!!!

 Hello I'm back! Today I am going to tell you about my science fair project. It is going to be like a behind the scenes on the science fair. 

First I am going to tell you about how I felt at the science fair. I was really nervous and scared about the science fair.  It was my first project that I had to present. It was not easy to pick a topic. There were lots of topics to choose from. I got my idea project idea from about chemistry.com.  My project title was "Can plants survive better inside or outside?" I chose this because I thought it would teach me a lot about plants and how they grow in the sun and inside.

All the things I needed for my project were 4 plants ,water, sunlight, inside lights, and a camera. My project was in the middle of easy and hard. The easy part was getting all the stuff that I needed. The hardest part was waiting for the plants to grow. Thats because it took a long time for the flowers to grow. One of the good things that happened was when I finally began to see that there was a difference in the flowers which was good. One of the bad things that happened was my other two plants had no difference. I think I learened that all plants need sunlight from the sun, water, and soil/dirt.  I was really happy when I was done presenting because I was not nervous.
