Why do boats float? Why do bowling balls sink? The children pondered…
During discussion, the children came up with some reasons why things float and sink. These included:
1. The buoyancy of an object depends on the material it is made of.
2. Air will make an object float.
3. An object with a heavy mass will sink.
After our discussion, the children performed a simple ‘float or sink’ experiment. They searched excitedly around the classroom, looking for items. They were curious to find out which objects float, and which sink.
First, we predicted whether the objects would float or sink. Then, we carried out our experiment. Finally, we recorded our findings.
The little scientists in class had great fun!
