In the video, adding more students is analogous to:

decreasing the volume of the canister

adding more particles of the reactants, which is increasing the concentration

adding a catalyst

increasing the temperature of the reaction

This analogy of going to a dance representing chemical reactions can help make understanding reactions easier, but it does not represent actual chemical reactions, obviously.
Give an example of a time you were trying to make something happen faster and what you did or could have done to speed it up? If you are stumped, try to think of something that you do in daily life and what you could do to actually make it go faster.
