IGCSE Biology revision video on enzymes

My Year 10 Biology group are all technophiles and love using their computers to revise. Sadly there is very little out there on the net specifically catering for IGCSE. CIE  do do a student site but I haven’t really clicked with it. So I am going to attempt to make a series of videos for IGCSE Biology (Cambridge). Hopefully by next year I will have covered the syllabus. The first one, on enzymes, is shown below. It is approximately 11 minutes long but should just squeeze into the usual, productive attention span.

Link to video hosted on screentoaster is:

I will be posting the teacher and student PowerPoint versions of the video later (again for free…I must me mad!).

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!).

Video on facilitated diffusion for Edexcel AS Biology

I am so proud! I have managed to make my first little video using Jing which was recommended to me by Jose Picardo of www.boxoftricks.net (excellent site by the way and I recommend adding him in twitter).

I have embedded the video below but there is also a link to a larger and better version stored on screencast.

If you use it in any of your blogs etc. please add a link to my site. I will be doing a whole series of little 5 minute videos on transport across the membrane so keep an eye out for those.

I am aware of the sound quality (you can hear me quite well but there is also a hum) and will be buying a better quality microphone. I managed not to say “er” too often but I did this by substituting the “ers” with “so”. I am half-irish so I reckon I can be forgiven for saying it, so!
