AS Level Transport across the membrane: Osmosis

This is the second in the transport across the membrane series of PowerPoint presentations. I am quite proud of some of the explanations and animations here. There is also a supporting video using the same presentation which maybe useful to watch (so you can see how I would explain each slide). This was originally written to support the concept approach Edexcel textbook but it can be used for any A level syllabus. There are integrated questions to encourage the students to apply the theory.

AS level video on osmosis

Well here is my second attempt at creating a screencast. This time I rose (or sunk) to the challenge of delivering AS level osmosis in 5 minutes! I deserve a medal! I have no idea if this is any good, it was a real squeeze to fit into the time limit. I redid it so many times I was beginning to get cheesed off. I still haven’t sorted the background hum or indeed stop my husband from yelling loudly whilst watching football (soccer for any americans out there) on TV (listen out for him..fortunately he didn’t swear..I think!).
The link to the better quality video on screencast is here: osmosis
