The Greenhouse Effect
Here is the class presentation – shadowed images are links. I’ve included the slides from G3 on the ozone layer. Make sure you understand that the greenhouse effect itself is a natural phenomenon, enhanced by human activity. Be sure also to distinguish between the greenhouse gases in the troposphere and ozone layer – they are in different positions, with different functions.

Classification
Grade 11 are starting out the course with a short “Nature of Biology” unit, made up of Statistical Analysis (and some practice with data), Classification, Evolution and a little introduction to ToK in Biology. Grade 12 are also looking at Classification at the moment, as part of the Ecology, Evolution and Conservation unit.

Proteins (AHL & C.1)
After the Carbohydrates, Lipids and Proteins last week, we’re taking a closer look at Proteins and their structures.
Here is the class presentation – click the shadowed images for links to animations:
Check that you know the different levels of protein structure, including the roles of hydrogen bonds and disulfide bridges. Think about how the properties of the R-groups on amino acids cause the protein to fold up in a set configuration.
Make sure you can give examples of fibrous and globular proteins and that you can name some examples of uses of proteins that are not structural or related to the plasma membrane.
The revision notes from Click4Biology are here.

Classification
Here’s the presentation for the Classification topic:
Follow the links in the images to learn more.
There’s a good wiki article on Classification here.
Here are some decent links to free organism identification resources:
Rapid Color Guides do loads of pdf files on tropical plants, lichens and animals.
The Mekong River has been extensively catalogued in terms of invertebrate life.
Riverwatch has a more user-friendly identification guide, that goes to Order level.
And a couple of rocky shore guides can be found here and here.
You can even carry out a virtual rocky shore transect from the British Ecological Society.
And there are a load of awesome resources at the UCLA OceanGlobe Student Resources site.
