Most children decided that the fruits or vegetables that are big and heavy would sink in the water, and those that are small and light would float. However, they soon discovered that this hypothesis is not always true. They were amazed to see a heavy pumpkin float and a tiny grape sink in the water. The boys and enjoyed observing the ...

Pumpkins are a popular decoration in the Fall and around Halloween. Pumpkins are a fruit, although some people refer to pumpkins as vegetables when cooking. Some fruits and vegetables float in water, and some sink. When an object floats in water, it is less DENSE than the water. When an object sinks in water, it is more DENSE than the water.

Displacement. If you sink you displace your volume. When an object sinks in water, it displaces its own volume. This means that the water level rises to match the amount of space the object is taking up in the water. If you float you displace your mass. When an object floats, it doesn't push as much water out of the way as if it would sink.

Which is more likely to float or sink? Buoyancy is the upward force of a fluid on an object that is immersed in it. Put simply, the more buoyant an object is, the more likely it floats in a fluid. In this activity, Ash and Linus test some objects in water, to see which will sink and float.

Whether an object sinks or float in a liquid depends mainly on two factors: density and buoyancy. However, at this level, students do not need to explain why objects sink or float. They are rather to be encouraged to observe that the same objects will sink or float every time, i.e., that there is consistency in the way the objects behave.
