SP3: Planning and carrying out investigations: To figure out more about density,volume, and mass we did an experiment in which we had giant tub of water. Then we had different types materials that all had different densities, mass and volume. Some of the materials sunk because they had more density and mass while some didnt because the had less volume and mass. We also tried to use aluminum foil we filed it to the size of the bin of water and put it in. It floated. But we folded it into a little square to make it more dense and then it sunk.
XCC: Cause And Effect: The amount of protons an atom has is what identify what type of atom it is. If your atom has a negative charge it is called a cation. This happens when electrons get added giving the atom an negative charge. If electrons are lost then the atom has a positive charge which makes it a anion. Cause and effect is very key in the atoms. So if a atom is positive its a anion. If it has a negative charge then its a cation.
