Conduct an investigation to determine whether the mixing of two or more substances results in new substances.
Develop a model to describe that matter is made of particles too small to be seen.
Make observations and measurements to identify materials based on their 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.
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 a model to illustrate that the release or absorption of energy from a chemical reaction system depends upon the changes in total bond energy.
