Summary:
       Atoms are the building blocks of life. Atoms are made out of protons, neutron and electrons and the protons and neutrons make up the nucleus of the atom while the electrons float around the nucleus. If an atom were blown up to the size of a football stadium then the nucleus would be the size of a marble. Neutrons have a neutral charge, protons have a positive change and electrons have a negative charge. The amount of protons identifies the type of atom it is. The periodic table is a list of all of the elements. Elements are made up of only one kind of atom and Density is how much stuff is in a given space. Volume is the amount s space that something takes up.

S&EP: Did you plan and carry out an investigation?
        To find out more about density, mass and volume we conducted an experiment to find out about the differences in between them. We had a tub of water and different materials with different densities, mass and volume to see what things had less density and would float on the water. Most of the things sunk because they had more density and mass and they all had the same volume. The things that floated were things like wood and things that were less dense and had less mass. We also had a piece of aluminum foil and when we had it in one big piece it floated but when we folded it and made it more dense and take up less volume it sunk.

XCC:Cause and Effect:
The amounts of protons in an atoms is what identifies the type of atom that it is. If you have an atom that has lost protons that causes it to have a positive charge because there are not enough electrons and it needs more. When an atom has a negative charge it is called a cation. If you have an atom that has an electron added it causes it to have a negative charge or a negative ion. because there are too many electrons and some should not be there. If an atom has a positive charge or a positive ion it is called an anion. The amount of protons effects the type of atom that it is and the amount of electrons effects if there is an ion and if it is a positive ion (cation) or a negative ion(anion).
