Internal Assessments
Grade 11 and 12 are in the thick of some IA work right now:
Grade 12: Self-designed Ecology lab
Grade 11: Factors affecting enzyme activity

Some things to remember:
1. Read the rubric and use the IA Checklist every step of the way!
2. Make sure you have sufficient, relevant data and associated quantitative data.
3. Don’t let Excel draw lines – it’s rubbish.
4. You must cite all sources of information using the CSE method (the superscripted numbers method which appears in Word as ISO690 Numerical).
5. Check your inbox for Turnitin setup emails and get set up.

Don’t forget the things you learned in the Statistical Analysis unit.

The Cardiac Cycle:
Hyper Heart animation and graphs from the Chinese University of Hong Kong
Biointeractive from the Howard Hughes Medical Institute
Control of the Heart Beat:
A few good links to try from Washburn Rural High School
And don’t forget the Medmovie resource…
Atherosclerosis and Coronary Heart Disease:
Medmovie has good animations for atherosclerosis, heart attacks and heart bypass surgery. There aren’t many that are better…
Digestion (Core)
New unit – Human Health and Physiology. Try to keep up…
Here is the presentation for the Core section:
Essential Biology 6.1: Digestion (Core)
Class Notes to fill in here (pdf download – A3 size)

Some good links:
Enzyme activity animations from McGraw Hill, Northland College and KScience.co.uk
A great animation/tuturial on digestion of different types of foods from kitses.com
And an introduction to absorption(and villi):

And, of course, here are JD and Turk to tell us about the diagnostic miracle of egestion:
Not a video, but…
… a great site for visualising data. InformationIsBeautiful.net.
Deadliest infections, from Information is Beautiful
I particularly like these posts:
How safe is the HPV vaccine? (in response to ridiculous scare-mongering news stories)
The Billion-dollar-gram (What is a billion, anyway?)
Ecosystems and Biomes
Final presentation for Option G: Ecology and Conservation uploaded!

Here are the Mighty Boosh telling us why Tundra is dangerous:
Population Ecology
Last topic of the unit! HL Students try to bring together all of the concepts we have learned through the unit when discussing how we can effectively manage our biggest shared resource: the fisheries.
Essential Biology G5: Population Ecology

Watch:
And don’t forget The Cove.
If you need to review, here is the presentation for Populations from the core:
Conservation of Biodiversity
This one is for the HL students in Option G: Ecology and Conservation.
Essential Biology: G4 Conservation of Biodiversity
Interesting article:
“Should Pandas be left to go extinct?” from the Guardian.
Proteins (AHL & C1)
Although we are learning this in the Chemistry of Life unit, it is actually part of the SL Option C and HL additional material, so look for the book chapters in the right place!
Essential Biology 7.5 & C1: Proteins
Proteins:
Life Cycle of a Protein from Sumanas
Making polypeptides from John Kyrk
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.
FoldIt!
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.
And don’t forget to play FoldIt – the brilliant protein puzzle that helps medicine!
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.
