because cork is less dense than water
As long as it can displace a volume of water equal to its mass (ie its density is less than that of the water) it will float. Most paper will have a density less than that of water (or can be so folded) so will float.
Sink. Items with a density of less than one will float on water.
It depends on theplywood density if it is denser then water then you would have to make a shape causing it to displace an equal or greater amount of water in weight for it to float.
If they float in water, then it is because the density of a ping pong ball is lighter than the density of water. The density of water is just below 1, and the density of a ping pong ball is much less than 1.
Their fins float and flatter in the water when they move.
A cork has a low density. It is lower then water. That causes it to float.

Because cork is less dense than water.
Cork is a light weight wood product that will float in water.
Cork does float in water because it's less dense than water.
it floats
Yes, a cork will often float on the surface of water, depending on the cork's density. But a marble will sink in water because of its weight. It will not float on the surface.
Only if the beaker is very full and the surface is rounded. Otherwise, the cork will float to the edge of the container (which is typically the highest part of the water).
If you dropped a cork in a container of water, the cork will most definitely float. As to the cork is lite, like a feather and it doesnt container much mass.
it float at the same level in water.
Wooden cork is less dense than the water and the iron is not.
anything that is less dense than the water, like a cork
