John Oliver: Climate Change Sketch

This funny (but sweary) John Oliver sketch skewers the non-debate on climate change.

“The debate on climate change should not be whether or not it exists, but what we should do about it.” 

With 97% agreement from scientists on the human cause of climate change, are the media skewing the debate with 1:1 representation?

This is connected to the Greenhouse Effect topic resources. Don’t play it in class without listening first – there is some strong langauage.

Review Vocab Quizzes with Quizlet

In this task we ‘crowd-sourced’ definitions and descriptions for a lot of the (lot of) vocabulary we have learned this year. This is to reinforce that Biology is as much a language course as a science course, and that everything is connected.

  1. Create a google spreadsheet with tabs numbered by subtopics covered
  2. Assign groups of topics to groups of students, with the simple task:
    1. First column, keyword, correctly spelled
    2. Second column: definition (exactly from subject guide if it exists) or clear description
  3. After groups finish, peer-edit
    1. Does it make sense? Are there any errors?
    2. It the definition clear in the ‘wider sense’ of the course?
    3. Adapt definitions with clarifications, or starters such as ‘process’, ‘structure’, ‘hormone’ etc

In our spreadsheet, we identified 312 terms (and growing) from this year.

Click to start a Quizlet set

In between sessions:

  1. Check and edit as much as needed/possible
  2. Import vocab into quizlet to create the set
    1. Very easy: select columns and paste into the right-hand field
    2. Make sure ‘tab’ is set, top-left
    3. Hit ‘import’ if it looks right
  3. Create quizzes/activities
  4. Share quizlet codes and  spreadsheet URL with students
  5. Get reviewing!

During classes: 

  • Students can review using the Quizlet activities
  • Students might use the vocab list to make sure they are meeting markscheme requirements for target language – are they giving complete and correct answers?
  • Students can use the vocab as a foundation for concept-maps, model responses etc.

Example (sadly Quizlet doesn’t embed to WordPress.com)

The Great Barrier Reef: An Obituary

The Great Barrier Reef: An Obituary. This haunting multimedia Guardian piece could be a perfect provocation for a unit.

The Great Barrier Reef: An Obituary. This haunting multimedia Guardian piece could be a perfect provocation for a unit.

In the current age of environmental destruction it can be difficult to keep paying attention to the news. But some stories stand out as being real alarm bells, and this very sad piece on the iconic barrier reef highlights a lot of purely human-caused issues. To add to the misery, now the reef is under further threat from destructive dredging and dumping… to make way for shipping lanes for coal mining in Australia. #EpicFail.

Ending Overfishing Animation

This is a neat animation by The Black Fish (@theblackfishorg) on Ending Overfishing, highlighting issues of overfishing, bycatch, fish-farming and the tensions between science-recommended catches and econonmy-driven catch limits. It connects directly to the Population Ecology option topic.

 

Ed Yong’s TED Talk: Suicidal crickets, zombie roaches and other parasite tales

“Are there any parasites that are influencing our behaviour without us knowing it?”

When I started this blog back in 2007, Ed Yong was a fledgling science writer gaining an audience with his Not Exactly Rocket Science wordpress blog; clear and engaging online articles that opened up primary research to a wider audience. You’ll find many links to his writing throughout this site, connecting the concepts of the IB Biology course to current science and ‘the wow beat’. He has since had a book and is resident at NatGeo’s Phenomena Salon, after moving through Science Blogs and Discover.

He continues to inspire me as a writer and this week he gave his TED Talk, a funny and fact-packed tour of the sinister side of parasites. Enjoy! You will even be able to find some links out to further reading and references.

If you don’t already, you should subscribe to the Phenomena blogs, and if you’re a teacher or student whose schedule are as packed a mine, I highly recommend Ed’s weekly ‘Missing Links‘ roundup of science news and writing – they make for my Sunday morning reading!

Niches for Species: How Wolves Change Rivers

This video is an excerpt from George Monbiot’s recent TED Talk (posted here a while back), and really sets up the imagery of an ecosystem as it responds to change. A great clip, well suited to starting off the Ecology units.

30-Minute Inquiry: Base-substitution mutations

This has worked well (and been fun) as a topic review, way to make use of databases (ICT in IBBio requirement) and make connections as we.

Question: What do HBB, PAH, PKD1, NF1, CFTR, Opn1Mw and HEXA have in common?

Concepts: Structure vs Function; Universality & Diversity.

The set-up:

  1. Assign groups by handing out cards with the codes above (we had already studied HBB, so didn’t include it) and asking them to find each other.
  2. Give them the instructions – to produce a simple poster & 1-minute overview of their disorder, using the guidance in the image below.
  3. Go.  Lots of discussion, lots of questioning. If students get stuck, they need to look it up, evaluate their sources and keep on going.
  4. Students will need to use the NCBI gene database to get going: http://www.ncbi.nlm.nih.gov/gene

Check they’re on the right track: HBB (sickle cell), PAH (PKU), PKD1 (polycystic kidney disease), NF1 (neurofibromatosis), CFTR (cystic fibrosis), Opn1Mw (medium-wave sensitive colour-blindness), HEXA (Tay-Sachs disease). They are all disorders causes by base-substitution mutations.

After 30 minutes:

  1. Groups present to the class what they have found.
  2. As the class sharing continues, ask questions based on connections:
    1. What similarities and differences do we see?
    2. What are the normal functions of these genes and how does this connect to our understanding of proteins, channels, pumps, etc.

Hattie & Yates: Visible Learning & the Science of How We Learn

This is my review of John Hattie’s new book, Visible Learning and the Science of How We Learn. If you’re interested, head over to my personal blog to read more.

Samudra, mini-me, having a good think about cognitive load.

Stephen's avatarWayfinder Learning Lab - Stephen Taylor

This brief review of John Hattie and Gregory Yates’ Visible Learning & the Science of How we Learn (#HattieVLSL) is written from the multiple perspectives of a science teacher, IB MYP Coordinator and MA student. I have read both Visible Learning and Visible Learning for Teachers, and regularly refer to the learning impacts in my professional discussions and reflections. While reading the book, I started the #HattieVLSL hashtag to try to summarise my learning in 140 characters and to get more people to join in the conversation – more of this below. 

EDIT: March 2017

This review was written right after the release of VLSL, in late 2013. Since then, the ideas of ‘know they impact‘ and measurement of learning impacts have really taken off in education, particularly in international schools. Critics of Hattie (largely focused on mathematics or methodology) are also easy to find, though the
