Biology4Good - Make A Difference!

Like an LCROSS missile ploughing toward the moon in search of water, there is an opportunity for this blog to go boldly in search of donations for charity. Click here or on the image below to find out more.

Click here to read a very encouraging article from the Gifts4Good blog!

The quality documentary juggernaut of the late noughties chugs along with another great piece of work, this time from the BBC. IB Bio classes – watch them!

Dr Adam Rutherford presents Cell, a three-part series on the history and great discoveries in cell biology. Although episodes are no longer available on the BBC’s website, AtheistPlanetBlog has uploaded them to YouTube, in six parts per episode*. Get it while it’s still there!

Episode 1: The Hidden Kingdom (playlist)

Get parts 2-6 on the playlist.

-

Episode 2: The Chemistry of Life (playlist)

Episode 3: The Spark of Life (playlist)

-

ToK issues and ideas of academic honesty abound in the series.

What is life and where does it come from?

How do we know that living things are made of cells?

What motivated (and still motivates) the great discoveries?

How and why did Virchow plagiarise Remak’s work on cell division?

What are the ethics of new and future developments in cell biology?

With over 1.5 million views and counting, check out this super high-speed motion capture of bullets penetrating various substrates, by the measuring equipment company Kurrzeit.

Beyond the traditional measuring  methods of Science and Engineering, high-quality, high-speed video allows for more detail and study of dynamic processes. We can see moments of impact or reaction, faster-than-the-eye phenomena and amazing natural events in detail and analyse them.

Check out this short clip of the fastest punch on Earth – the Mantis Shrimp. The strike through water is so fast that the water around it is boiled due to the pressure, and the impact is so hard that it looks as though the carapace (shell) of the crab is momentarily liqeufied. Read more about the mantis shrimp punch at NotRocketScience.

Stay tuned for more high-speed science videos.

*I don’t really, but would love it if you made a donation to charity through Biology4Good, my list on give4good.

One great enzymatic dollop, for the core content and AHL/ SL Option C. Make sure you use this theory in your write-ups, can relate the action of enzymes to their structure as proteins and look for examples of enzymes in action throughout the course.

Essential Biology 3.6 & 7.6/C2: Enzymes

-

Check out this article on the potential use of an enzyme in second-generation biofuels.

-

Enzyme Basics:

What is an enzyme? from Northland (the best one – including inhibitors, pathways and feedback inhibition)

How enzymes work from McGraw Hill

Enzyme basics from KScience.co.uk

A full collection of savable enzyme animations from Husam Medical

And John Giannini’s Enzyme collection is nice and clear.

-

Enzyme activity and kinetics

Nice virtual lab from KScience.co.uk

Enzyme kinetics from Wiley Interscience

And here’s a quick run down on YouTube:

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.
