Matter

We feel like we are solid but we are mostly liquid. We are made up of mostly Oxygen, carbon, hydrogen, and nitrogen. Matter is everything to a cup you drink from to a car.. Everything is made up of atoms which are made up of protons, neutrons, and electrons that go around the nucleus of the atom. There is very little ordinary matter there is more dark matter dark energy.Dark matter is not like ordinary matter you can not see it it is invisible. Dark energy they say is stuff that is making the universe expand but they are not convinced that Dark energy exists. Living matter makes stuff that are alive like you or me. Nonliving matter is like rocks, cups, balls, and books they are not alive.Einstein discovered that a very little bit of matter can make a lot of energy this is like the sun which helps things on earth to live.Earth is made up of about one hundred elements, the elements are made up from atoms if we combined any of these elements we can get nearly everything on earth. Cells build mostly everything but a leaf we can't understand how it lives and dies. Like living things a toothbrush are built from atoms but in a tooth brush there are stretchy molecules which is why it makes some plastics so flexible.
