Category Archives: Floating/Sinking
The last week of October, we had some pumpkin investigating going on and here are a few of the activities we did:
First, we asked the children to tell us if they thought the mini pumpkins would sink or float. They made their predictions by placing a sticker either above or below the water line. Then we tried it and talked about why it floated.
After that, some one asked if a carved pumpkin would sink or float, so I hollowed out a tiny pumpkin (tough to do!!) and then we predicted again–it floated. We talked about density and the air in the walls of the pumpkin and then we tried floating an apple–it floated!
