Sink or Float?



Last week, we filled the sensory table with water and put out many different materials on a nearby table. There were wooden blocks, straws, foam blocks, paintbrushes, and stones. All of these materials, the water, and one question provoked lots of experimentation: Will the material sink or float?

The children explained that when something floats "it stays at the top" and when something sinks "it goes under the water." With these definitions, the children began experimenting. They then recorded which items sank and which floated. When your child is playing in the tub or even in the sink, you might want to experiment and find out what you can get to sink or float!
