Daddy gets involved with our projects sometimes....this project wasn't even planned! I got this planet placemat from Walmart a year or so ago for 97 cents and the balls, we just had lying around the house. Think we have enough balls for the two boys?!?!
The boys had a great time comparing sizes of planets and deciding which of their balls would represent each planet. The boys really seem to enjoy science, so I'm sure they will be testing their mother, the least science minded person on THIS planet.
