Science - structure of matter

The ocean is made of hydrogen and oxygen (water), salt, plants, sand, sea creatures, and rocks.
Instead of doing an experiment about this, we could just go catch a fish in the ocean, and from there on, think logically. If there is one big fish, there must be smaller fish for that fish to eat, if there are smaller fish, then there must be plants and rocks for them to feed on and hide in. We know there is sand on the bottom of the sea, and if not, then just go bathing. We also know that the sea is made up of water, because fish can only live in water. 

Sea water is made up of salt and water - you could prove this, by dropping a snail into sea water and see what would happen. If there really was salt in the sea water, the snail would start dissolving.

Beach sand is made of sand, little rocks, different sorts of seashells and animals like crabs. You could prove this by putting the sand into a collander and then all the rocks and seashells etc. would stay in there.

Salt is mainly made from sodium chloride.

Silicon is an element, so it is made of electrons, protons and neutrons. If you wanted to be sure of this, you could just go check out the periodic table.

Chlorine is an element made up of electrons, neutrons and protons. Again, if you wanted to be sure of this, you could look at the periodic table.

Protons and neutrons are made of quarks and gluons.

I think electrons are in a way made up of energy.

I think energy can be made from movement, water, electricity etc. for example, we use wind turbines to create energy, we also use water and other sources to create energy.  If we rub our feet against a carpet or a balloon we create electric energy, that is also how you could prove it.
