The differences in Earth's seasons isn't caused by how far the sun is away from the Earth. It is simply because of the tilt of the axis. The earth's axis is tilted by 23.45 degrees. The tilting is what gives us our different seasons. Since it is tilted, different parts of the Earth are oriented towards the sun at different times of the year. Summer is the warmest because the Earth is tilted directly towards the sun and Winter is the coldest and without sun the most because it is tilted the farthest away from the sun.
I enjoyed reading this. It is simple and to the point. You don't beat around the bush. I think that fourth graders would be really interesting to know about how the planets tilt. I think you did a great job!
