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.
Measure and graph quantities to provide evidence that regardless of the type of change that occurs when heating, cooling, or mixing substances, the total weight of matter is conserved.
Develop models 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.
Construct an argument with evidence that some changes caused by heating or cooling can be reversed and some cannot.
Plan and conduct an investigation to describe and classify different kinds of materials by their observable properties.
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.
Develop a model to describe that matter is made of particles too small to be seen.
Conduct an investigation to determine whether the mixing of two or more substances results in new substances.
