How to Speed Up Chemical Reactions (and Get a Date)
How are chemical reactions like dating? A collision must first occur! In this hilarious approach to speeding up chemical reactions, viewers find out that five changes can increase the rate of reaction: smaller space, increased number of particles, increased temperature (and therefore velocity), increased surface area, and adding a catalyst.

Concentration and Reaction Rates
Students investigate how varying the concentrations, volumes, and other factors affects reaction rates. Students design and conduct investigations to obtain data used to create graphs of an uncatalyzed reaction vs. a catalyzed reaction. Students use retest methods to determine how using various amounts of initial reactants changes the reaction rate.
