Here is a new (and helpful) infographic for HL Bio, “The Path to ATP”. Think a simpler version of Gerhad Michel’s famous Roche Biochemical Pathways.
Pitched just a little over HL, but very well done and super catchy, here’s Wilson Lam’s Thrift Shop Parody:
Related, of course, is Tom McFadden’s Oxidate It Or Love It:
And if all that’s too musical, here’s Hank:
This is a neat connection to the properties of water:
I forgot this existed…
This is designed to address some of the assessment statements for the Chemistry of Life unit, and to provide a clear wall-chart that is free to use and free from advertising. I recently updated it with relative atomic masses and a couple of corrections. Download the full A0 poster here: http://is.gd/iBiologyPTable.
On a related and interesting note, here’s a little video by Periodic Videos on the Japanese discovery of element 113:
In tomorrow’s class we’ll be reviewing our Making ATP unit (enzymes, cell respiration, photosynthesis and the greenhouse effect) with a couple of concept mapping activities. The first, cell respiration core, is made using the really useful free concept mapping tool from IHMC CMap tools. This is a freeware package for most computing platforms – very easy to use and might be a help in your revision!
In the second activity, build your own concept map making as many annotated connections between concepts as you can. Surrounding this, add and annotate the relevant graphs and diagrams.
CrashCourse Biology is a new(ish) and definitely more entertaining and engaging alternative to Khan Academy. Hank Green follows his brother John’s example (World History) and is producing some pretty funny, fast-paced and visual presentations for key concepts in Biology. One feature I like is the short ‘history of the idea‘ section in each video.
Here’s an example on the properties of water:
Another feature I like is that the video description has links to sections within the video, making review easier. He also includes a set of citations (more like links to follow to find out more). So although they can be embedded, you are much better off watching them on his channel.
Hank also has another channel, SciShow, which has short, sharp videos on science – whatever the topic. Here are a couple of examples from his playlist.
FoldIt (MrT’s favourite game):
And this on Mendeleev’s Periodic Table:
I first heard about these channels via Fractus Learning, but didn’t get a chance to look until this weekend, searching for periodic table resources and Lewis Dots. When Crash Course popped up again, I figured it was time to have a look.
In 2011, Drew Berry’s animation of the role of breast stem cells won the Imagine Science Film Festival award for visual science (posted here). In this TED Talk, he explains how and why he and his team have put together these accurate representations of invisible cellular processes. The talk shows some examples of the animations, including a really great segment on mitosis and what is happening when spindle microtubules attach and contract.
For more excellent animations, visit the Walter and Elizabeth Hall Institute (WEHI) TV Channel: http://www.wehi.edu.au/education/wehitv/, or their YouTube channel.
The effective communication of Science is an Art.
Neil deGrasse Tyson presents this short PBS NOVA overview of how epigenetics determines the differences between gene expressions in identical twins, how epigenetic variations build up over time and how it affects us. A relatively new, but very interesting field of medicine and genetics, this is a good introduction.
Epigenetics is not directly mentioned in our syllabus, but does help us to connect the ideas of nature vs nurture, genetic variation and inheritance. To what extent does the nurture of our cellular environment (lifestyle) affect the genetic nature of who we are?
For some more really good resources on epigenetics, visit the brilliant Learn.Genetics site from Utah.
