Do pumpkins float?

Pumpkins are rather large fruits and kids will often predict they will sink because of the size.

The fall fruits contain a lot of air (even pumpkins because they are mainly hollow inside despite their size).

What makes something sink or float?

The huge pumpkins will bob in the water with part of the pumpkin in the water. Science can be fun! Without even knowing your child is practicing the crucial science skills of prediction, experimentation and reasoning. Density is what makes something sink or float, not weight.

Do fruits and vegetables float or sink in water?

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. DENSITY is how closely molecules are packed together in a solid, liquid, or gas.
