Objects float or sink because of their density.
An example of an object with low density is a sponge, as it has loads of air bubbles in it, and will float.
An example of an object with high density is a brick. This is because the brick doesn't have any air trapped in it, it is "packed in", and is more dense than water, therefore it will sink.
Well, a sponge sinks if there is too much water in it. Basically, if a sponge takes in water, it gets heavier and sinks. Normally, a sponge floats, but if you pour 10 cups of water on it, I bet it will sink.
Some types of sponges float, and others sink.
If the sponge soaks up water, then sinks, it means that the sponge material is actually denser than water, and the sponge was floating due to the air spaces in it. Once all of the air spaces fill up with water, its average density goes from less than water to greater than water, and it sinks.
When water replaces the air in a sponge, it can no longer float. The air is what causes it to float.
Because the sponge is less dense than the water
sink, because it absorbs water then weighs to much for the water to hold then sinks.
Yes
Oh that's quite simple. Find a sponge and get a bowl. Put the sponge in the water and explain how the pores in the sponge suck in the water as you put pressure on it. As you squeeze it explain that the pores release the water through them.
When you put a science tool in water it doesn't sink and in olive oil it does sink
yes because all sponges have pores and certain materiel does not have many pores.For example a piece of foil compared to a sponge the foil is not going.
tiny "whips" on the cells inside a sponge draw water in through the pores of thesponge. Food is then removed from the water before it leaves through the opening at the top of the sponge .
cotton does soak up a little water. It soaks up water cauzz it has litttle air holes just like the sponge...but it is not made of the same material as sponge soo it wont soak up as much as the sponge
rocks metal eggs dirt or sand all sink some woods sponge plastic aluminum cans all float
If an object is less dense than the substance it is placed in, it will float. For example, a sponge is less dense than water, so will float. However, if you squeeze the sponge underwater so that it has no air left in it, it will sink, as it will be the same density as the water.
When a sponge is submerged in water, the water enters the sponge through the tiny holes in the sponge. The sponge fills up with water, as a balloon fills with air, only not as visibly. When you squeeze the sponge, the water exits that sponge through the tiny holes...exactly the opposite of how it entered! Tada! :)
a sponge holds water because of its holes
A sponge is something that has allot of holes, but can still hold/soak up water.
The part of the sponge the water flows in is the hole.
The size of a sponge does affect the amount of water absorbed. The bigger the sponge the more water absorbed.
A sponge
He has gone out of the water before and been fine.
Maple syrup will sink but water is unable to sink because it is water.
the water sink is not solid and liquid
object that sink in water
