Since I teach life science many of the concepts are too widespread (food webs) or take extended periods of time (genetics/evolution) in order to see results. Experiments can be done on cell processes, but these occur at the microscopic level and are hard to see. Computational models will allow students to gather data on processes that they typically cannot see.
The experimental design process is similar in that students need to predict outcomes, choose variables, and gather data. The method of gathering data is quite different and different types of analysis can be done with a computer.
