There is this formula also that I don't understand something about VOLdisp=VOLobj = M"loss"=Mdisp. I need more information on that.

Think of large graduated cylinder and some sort of object that will sink in it (like a rock)
If there is 2 liters of water into the cylinder, then put the object into the water you will see how the level of water in the cylinder has moved up (say to 2.5 liters)
The Volume of displacement is how much the water level changed. (in this case .5 liters/half a liter) The volume of the object would be that amount because it is the amount of space that it took up while in the water.
So the Volume of the displaced water is equal to the volume of the object. (think of the volume of the object as how much water it would hold if you filled it up with water)
I dont know about the second part of the equation, I dont know what M"loss"=Mdisp. what does the M stand for?

Archimedes Principle For Kids

Archimedes Principle can be simply stated that an object floating in water displaces a volume of water equal to the weight of the object.
As another answer stated, you can show it with an experiment.
Logically, you can also see that an object that is more dense than water will sink and displace it's own volume.
More generally, Archimededs priciple can be applied to the calculation of specific gravity. It is why water has specific gravity of 1 (unity).

The principle of relative density is the key behind the body mass index. If you put 2 people of equal mass in a graduated tank of water, one at a time, you can derive their relative density by the change in volume in the tank. The best readings are taken when the person is submerged with lungs emptied. Mass is divided by volume for density, plug that figure into the body mass index, and you get your approximate percentage of body fat.
If your overall density is less than water, you'll float and lose your contact with the bottom.That's why the tank has handles to hold yourself under, or else they'd have to use the principle of buoyancy also

It's more about density. Explain to the kids first of density and how a less dense object floats on a denser object. Then, you can move towards how volume and mass plays into the role of density.

You must be at a school with very lax rules. In the vast majority of schools you cannot have a phone in class without it being taken away by the teacher. If the school does not have good discipline from class to class, then it will be hard for you to have discipline. I once took over a class from a teacher who could not handle the class. They were a little younger, but I had to start with things to keep them busy. I gave them outline maps and they had to write in the names of the countries. Give them something educational to do, rather than just listen to you.
