PhET! Using simulations in general-education labs
Simulations from Colorado’s PhET project have been successfully used as pre-labs and as lab substitutes in my general education courses. I will present one or two examples of how I have adapted them for chemistry and physics courses. Other examples will be available as handouts.

A successful student-designed experiment in calorimetry
An important problem with student-designed experiments is that students are inhibited by their lack of knowledge. This lab takes the time to teach students to use the equipment, then turns them loose to come up with a procedure to accomplish a stated goal.

Carbon dioxide emissions associated with generating the electricity used by electric vehicles can be determined, and compared with the carbon dioxide emissions associated with internal-combustion vehicles, including hybrid-electric vehicles. When emissions from electrical generation are taken into account, electric vehicles that obtain power in most U.S. states have lower emissions than gasoline-powered vehicles, but in some states the heavy use of fossil fuels for electric generation causes electric vehicles to do no better than gasoline-powered hybrid vehicles. In a few states, electric vehicle emissions are worse than those from comparable hybrid vehicles. We will present the data, and discuss possible ways to use it in chemistry courses at all levels.
