Ivory Boat Sink

After the students demonstrated their skill at creating soap boats that floated, I challenged them to create a soap boat that would sink. With this experiment the students had to carve a boat shape they thought would sink. Many thought that it would be no problem to sink a bar of ivory, all they needed was to put a hole in the bottom.







The experiment surprised most of the students, they discovered that Ivory soap would not sink in the water. Here is why.

Great project. The kids look like they are really enjoying it. Thanks for sharing this wonderful idea. Very Smart, carving the soap outside - seems so logical,but I probably would have made the mess inside!

Hey Tyler, we miss you too. Say hi to your sisters for me. Everybody seems to be enjoying the experiments, soon the kids will be making their own boats made out of craft sticks for our annual Boat Regatta.
