How Many Puffs of Air Does it Take to Move Objects?

All you need is a table, chart paper, marker and "stuff". The stuff can be toys, markers, blocks, paper, food or anything you find in a typical classroom.

You make predictions about many times you would have to blow to move the object to the other side of the table. Next, you pick a student to blow the object off the table.

We were amazingly surprised how hard it was to move things like sunglasses, and how easy it was to move a dice.

At the end, the kids discussed what was the easiest to move, hardest to move, what they would try again, and so on.

It was a lot of fun, covered predicting, recording, trials, weight, surface area and writing!
