Change in Matter

Conservation of Mass- PS1.B.3-Use symbolic representations and mathematical calculations to support the claim that atoms, and therefore mass, are conserved during a chemical reaction.
Equilibrium- PS1.B.2- Refine the design of a chemical system by specifying a change in conditions that would alter the amount of products at equilibrium.
Energy in Chemical Reactions-PS1.A.5-Develop a model to illustrate that the release or absorption of energy from a chemical reaction system depends upon the changes in total bond energy.
Reaction Rates-PS1.B.1-Apply scientific principles and evidence to provide an explanation about the effects of changing the temperature or concentration of the reacting particles on the rate at which a reaction occurs.
Nuclear Reaction- PS1.C- Use symbolic representations to illustrate the changes in the composition of the nucleus of the atom and the energy released during the processes of fission, fusion, and radioactive decay.
