Bryan - the divice is tricky to work, but with effort, would make a better demo for the class than a class lab.

Ken- This lab didn't work because a seal with the O ring would not form. Some people got it to work, but most students would not be able to do it.

Louann-- This is one if those activities I've always seen in textbooks. Even though we didn't get good results due to the O-ring leak, I still think this is a worthwhile kit. I would tie the bottom of the tube and try using both O-rings at the top. I like the idea of being able to measure results.

Deb- We had a problem with this lab. And if we did, i know the kids would lose patience. I might suggest this for an AP or second year Bio class. Even for those that got it to work, there isn't enough 'wow' factor for the first year students I would have.

Heather - Connecting the dialysis tubing to the equipment takes a very careful and steady hand not to tear the tubing. Getting a tight seal is difficult. Perhaps this would make a better demo for a freshman bio class, so they don't get frustrated!

Emily- Very difficult to set up. Other osmosis labs may be easier for students to manipulate. The plastic containers were a good idea that was provided for the lab, but setting the O rings on the dialysis tubing was extremely difficult.

Carrie - This was a very difficult lab to set up. I feel my freshmen would not have the patience or the skill to manipulate the dialysis tubing around the osmosis apparatus.

Alicia- I see what this lab was supposed to show but unfortunatly it takes too much set up to actually get it to run

Christine- I liked the apparatus and set up for this lab. I think that for those on a budget, it might be better to simply replicate this with dialysis tubing and typical glassware. It was really neat to see the solution move up through the apparatus to indicate that osmosis was occurring.
