This site is great. I think any student who interacts with this page will come away knowing more about cell membranes. I thought the images/pictures were great. I also really liked building the cell membrane and throught the questions were good. The site was easy to navigate, and the content was super. I spent about 15 minutes browsing the site, but when I made up a worksheet to go with it, I stayed on for about an additional 20 minutes.
