How We’ll Stop Polio for Good
This TED Talk by Bruce Aylward is amazing – watch it! Particularly important for HL Biology students.

i-Biology: Illuminating Science!
Here’s a cool little TED video of bioluminescence in action.
https://ted.com/talks/view/id/1149In case you forgot, bioluminescence is the end-result of transcription and translation, with enzymes being produced to catalyse light-emitting reactions. Try it here at Learn.Genetics (What makes a firefly glow?). A beautiful real-world example of this semester’s content in action.
i-Biology.net Domain upgrade
You might have noticed a new domain name and shorter URLs here – I got a new domain! It is domain-mapped through WordPress.com, so you shouldn’t need to update your bookmarks (but you might). Four years ago, this site started out as ‘Science Teachers’ Video Resources‘ but has evolved into something much more focused.
So here it is: i-Biology.net. Short and easy to remember.
The main focus of the site is IB Biology, but there will continue to be lots of videos and interactives linked for other sciences – especially as I will be moving soon to teach MYP science in Japan.
The “i-” could be “international” or even “I-love-” Biology. It’s up to you. I quite like “illuminate”.
With all the resources here now, “i-” should really mean “independent“. If you can support your own learning as a student by using this site, then great! What I really hope is that it will keep you “inspired” to continue Science beyond school.
As always, constructive comments and charity donations via Biology4Good are welcome.
Biology4Good – please help make a difference.
What a week – over 20,000 visitors around the IB Biology exams! I hope it went well for you all, especially my awesome BIS kids!

Apologies for two very similar posts in a week – I wanted to catch you before you left and perhaps never came back to the site now that IB exam stress is done!
MrT
Pay It Forwards – Please!
I hope Paper 1 and 2 went well for all you May-sessioners today. I can see from the stats that many have been busy on this site, and I’ve had three record-breaking days in a row. Many of you may never come here again once IB is done, so I wanted to catch you before you left!

Good luck for tomorrow. Put today out of your brain and look only at your Options work. Pay attention to command terms and don’t foolishly think you can do an Option that you didn’t do in school.
For many of you, tomorrow marks the end of the IB Diploma Programme. I sincerely hope that it has helped you grow into decent human beings – compassionate, knowledgeable and motivated to make a positive impact on the world.
BIS students – I am proud to have been your teacher.
Everyone else – thanks for the comments!
MrT
Good Luck for Tomorrow!
Sleep tonight, not during the exam.
After all your work, you should be well prepared, but there are always last-minute strategies that you can take on board.
1. Get some sleep. Zombies are generally rubbish at Bio exams. Scientists are yet to determine whether this is because of changes to their brains or if they just can’t hold a pen. I’ll see you in the morning for any panic questions.
2. Pay attention to the Command Terms! We’ve been over this, so don’t forget.Don’t make the mistake of writing a beautiful answer to the wrong question!
3. Make good use of the reading time in paper 2 and 3. This is an opportunity to think about which question(s) to choose in section B and how you are going to structure the answers. Knowing what’s coming up will help you pace yourself.
4. Stay inside the boxes on paper 2. It will be scanned and the bits in the boxes sent to the examiner – who cannot mark what he/she can’t see!
5. Write clearly and use language appropriately. Make it easy on the examiners – they could have hundreds of copies of the same question to mark, so get your ideas across succinctly.
When you’re done, get some rest and focus on Thursday’s Options. You know it, so be confident.
