I'm sharing what I used for a chemistry review project with my students this past year. They have to get ready to take the New York State Chemistry Regents exam where they must know quite a number of definitions and facts. So I divided with work between students in both my classes and gave it a try. I then put together all their short videos into one longer video for them to watch and hopefully retain some information. I graded mine as a quiz.

to see state-specific standards (only available in the US).
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. Emphasis is on simple qualitative models, such as pictures or diagrams, and on the scale of energy released in nuclear processes relative to other kinds of transformations. Assessment does not include quantitative calculation of energy released. Assessment is limited to alpha, beta, and gamma radioactive decays.
Use the periodic table as a model to predict the relative properties of elements based on the patterns of electrons in the outermost energy level of atoms. Examples of properties that could be predicted from patterns could include reactivity of metals, types of bonds formed, numbers of bonds formed, and reactions with oxygen. Assessment is limited to main group elements. Assessment does not include quantitative understanding of ionization energy beyond relative trends.
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. Emphasis is on the idea that a chemical reaction is a system that affects the energy change. Examples of models could include molecular-level drawings and diagrams of reactions, graphs showing the relative energies of reactants and products, and representations showing energy is conserved. Assessment does not include calculating the total bond energy changes during a chemical reaction from the bond energies of reactants and products.
Refine the design of a chemical system by specifying a change in conditions that would produce increased amounts of products at equilibrium. Emphasis is on the application of Le Chatelier's Principle and on refining designs of chemical reaction systems, including descriptions of the connection between changes made at the macroscopic level and what happens at the molecular level. Examples of designs could include different ways to increase product formation including adding reactants or removing products. Assessment is limited to specifying the change in only one variable at a time. Assessment does not include calculating equilibrium constants and concentrations.
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. Emphasis is on student reasoning that focuses on the number and energy of collisions between molecules. Assessment is limited to simple reactions in which there are only two reactants; evidence from temperature, concentration, and rate data; and qualitative relationships between rate and temperature.
