Mrs. Yollis’ class was talking about how the Earth orbits, or goes around, the sun while spinning itself!
That topic interested me, so I made a model at home to help inform the class about how this system works. I researched using books and the Science links on Mrs. Yollis’ Website.
Here is what I have learned. The sun is approximately 4 billion years old and is a star made of gas. In fact, it is made up of 70% hydrogen and 28% helium. The Earth is one of eight planets that make up the Solar System. It takes a year, or 365 days, for the Earth to travel around the sun.
On my model, the Earth is colored blue and green. Blue stands for the oceans, and the green is for the continents. There are seven continents on our planet: North America, South America, Asia, Europe, Antarctica, Africa, and Australia. I made the sun small so it looks far away.
I love the solar system, and I hope you do too!
