We then broke into two groups and made observations about the outside of our 2 pumpkins. We counted the lines, felt its texture, and picked it up to see how heavy it was. Then we predicted if we thought the pumpkin would sink or float. Twelve thought the pumpkin would sink and twelve thought it would float. Guess what?!? It floated!
We measure our pumpkins using linking cubes. First we wrote our estimates on the chart. Then we measured. Most of the students realized that the smooth pumpkin was taller than the bumpy pumpkin so the estimates were greater for that pumpkin :)
We had one correct estimate!
Next we estimates the circumference of our smooth pumpkin. This was a little harder!
