“We all know the sun is hot, but the outside bit of it is hotter than it is supposed to be. I am trying to work out why this is.
To do this I take a small bit of the sun and put some thing that looks like it in my really big computer. The computer then makes it act like the real world.
Then I shake it at the bottom and watch how bits of it move up and down. We think the waves this makes might be helping to make the outside bit of the sun hotter than it is by moving the hot from the bottom to the top.
Once I have done this I then look to see how different shaking changes how much hot has been moved from the bottom to the top. We can see different types on shaking on the the sun so I can work out which ones we see will move the most hot from the bottom to the top.”
