Ken- The methods for students to prepare the tubes are complicated. Also, this lab requires equipment that is not always available in every school.

George - This lab was tedious. Once we finally got into a rhythm it went very well. This would work with groups of 4 - 5 students. There is a lot pf prep required. Not a bad lab overall.

Emily- This lab was a struggle...The instructions were very detailed and at times complicated to follow. The steps were however, repetitive which aided in the process. Way to much for the average student and even the average honor student.

Keith - This lab would probably be fine for the first year college audience, but a detained pre-lab would be essential. The more detailed, the better. The nice thing is that the lab yields numerical data, that can be manipulated and modeled in Excel, or an equivalent spreadsheet.

Heather - The lab required quite a bit of precise lab work (timing, measuring, following directions quickly and correctly) for a introductory class. It's easier to do this lab with a spec 20 and just taking data over time, avoiding the assay and making multiple samples. This lab may be modified for AP Chemistry... maybe the kinetic reaction order could be determined/application of Beer's Law?

Kathy - Nice way to quantify enzyme action.

Deb- I didn't like this one as much as one I did last year. Maybe it could be used with a higher level chem class that uses spectrophotometers, but I thought it took a lot of time and didn't really show much. Maybe the graphing aspect would make it worth it.

Christine- I enjoyed this lab in that it gives the students doing the lab an opportunity to work with instruments that are not always found in a typical high school classroom. I think it is essential to be sure this is done with a very advanced group with lots of prep in the usage of the instruments. It will help to prepare kids that are in an advanced class for college if they are going on a science track. On the other hand, there are several different ways you can go with looking at factors that effect enzyme action that can be more appropriate if you want to achieve the same objectives with a younger or less advanced group.

Carrie - While this lab utilizes equipment not found in every high school lab, this lab was an interesting way to view enzyme activity and the quick changes that occur. This was a good college prep lab.
