Planetery science: Making a solar system display with clay planets

My son got interested in planetary science just after his 2nd birthday in January. It was end of his fire engine obsession and beginning of stars and planets obsession. He knows names of all planets, sequence,their colors and relative sizes, their moons etc. (I read planetary science websites and books everyday to keep up with his questions.. ooh these never ending questions..sigh) 

So early in June, I had made planets from air dry clay. I made them in relative proportion of their sizes. Over the coming days in our afternoon activities , Avaneesh had painted them as per their colors. Then I kept them in a box on his table for many days. He would play with them everyday.

After a month. I thought we should glue them on to a board so to make him understand how planets rotate around themselves and around the sun. So I cut a big circle from a Styrofoam board.It was hard to keep Avaneesh away. He was jumping with excitement. I drew orbit around a imaginary sun in the center. Avaneesh kept on saying Where is Sun? I told him that you will paint it later lets first just put these planets all in place.  

 I put glue drops on the orbit circles and told him to press the planets in place. He placed all the planets in sequence. 

Then I made a big ball from the extra clay I had and gave it Avaneesh that this is Sun. He was happy to finally have Sun in the solar system. 

We also talked about how planets go round and round around the sun and around itself. Then I told him that imagine this is sun and we are planets. Avaneesh and I went round around the table and then going around the table going round ourselves. Oh my God, my head started spinning. I stopped Avaneesh as well.
