EXPERIMENTS WITH
WATER
WHAT FLOATS – WHAT SINKS
If the weight of an object is
less than the water displaced
by it, the object will float on it.
If the weight of an object is
more than the water
displaced by it, the object will
sink into it.

WHAT FLOATS – WHAT SINKS
If the weight of an object is

If the weight of an object is
more than the water
displaced by it, the object will
sink into it.
SALT
Salt makes heavy things float in water.
When we cook eggs and put salt in the water,
the eggs start floating.
The Dead Sea is a great example of water with
a lot of salt. All oceans and seas have some
salt, but the Dead Sea has the most.
Even if someone can't swim, they won't sink in
the Dead Sea because it has so much salt.

WHAT DISSOLVED, WHAT DID NOT?
There are several things that disappear
in water when we add them to water.
They are called soluble substances. 
There are several other things that do
not disappear in water but settle down
when we add them to water. They are
called insoluble substances.
