Hans Rosling (1948-2017)

“Fame is easy to acquire, impact is much more difficult.”

Hans Rosling, 1948-2017 (Guardian, 2003)

Hans Rosling, public health guru, statistics wizard, creator of Gapminder and presenter of the best TED Talks of all time (playlist), has sadly died, way too young. Any long-term user of will know what a fanboy I am, and there are many posts and pages on this site – from Bio content to MYP and TOK – that reference his work and talks.

He will be missed but his work, more important now than ever before, will live on.


We’re lucky to be in this world. Don’t be ignorant.

How NOT to be ignorant about the World: Hans & Ola Rosling

Another great Hans Rosling TED Talk, this time with his son, Ola. Here Dealing with misconceptions, bias, ignorance of global issues and a little formative assessment, they discuss how we can be better informed about the world, with a fact-based world view… and how we could (eventually) perform better than chimps on a global issues quiz.

This would make a great provocation for a TOK unit, or one in Geography or a Global Issues group. In our field of international education it might be useful for parent and teacher training, considering why we need to educate for global understanding, not just for disciplinary knowledge. Through a fact-based world view, we can develop truly internationally-minded, globally-engaged young inquirers, who recognise their biases and know how to learn more about the truths of the world we live in now and into the future.

I love the suggestion they have of a “global knowledge certificate” for agencies, schools and employers that is based on candidates taking a test on the fact-based world view. You read about the ignorance project here on CNN, or find more classroom resources (including a world-view card game) on Gapminder’s education page. The Guardian also has a selection of global development quizzes, which you can take for fun or in class.

Hans Rosling’s Joy of Stats

Now available in full, this one-hour documentary is on Hans Rosling’s GapMinder website.

A brilliant, visual and entertaining view of 1.1 Statistical Analysis, using real datasets and graphics to highlight statistics, means, distributions, graphical representation, correlation and cause. It is most relevant to us from the start up to 37:30.

Here is a neat clip from the show when it aired on the BBC.

G4 Project Archives

Here are some resources from past Group 4 Projects.

2010: “How can Science help re-build a stable and sustainable economy?” Outline Sheet (Word 2007)

2009: “How can Science aid progress towards the UN’s Millenium Development Goals?”

Tick-tock. With just five years left to achieve the UN’s Millenium Development Goals, what role can Science play in progress towards them? Each group will focus on a different MDG, and your project will look at progress, ideas and measurement.

There is a feed of global development information at the bottom-right of this website. You can also keep up with the Guardian’s Global Development Website.

Here’s MrT’s hero, Hans Rosling talking about successes towards the MDGs:

The UN's Millenium Development Goals - which is your focus?

2008: “How can Science help solve global environmental issues?”

Half a million views – so who are you all?

Another busy week at BIS, and a great Unity in Diversity Day!

This site just passed the 500,000 views mark, which is not something I expected when I started it as an experiment in blogging, ‘Science Teachers’ Video Resources,‘ a few summers ago. It’s morphed into a resource-bank for IB Biology and Science in general, and grows as I find more and more great links for learning about the scientific world.

The resources posted here are first and foremost for my own students – to help them go deeper into Biology and to open the door to the trans-disciplinary realms of Science. It’s great that it has become a useful tool for other students and teachers, and I hope that this is a sign that the resources here are useful. It is great to receive emails and comments from people using the site – especially when they spot a mistake and then I can get it fixed!

I don’t really know who is using this site beyond my students, so please leave a comment below to let me know who you are and what you do here. Even better – tag yourself or your school on this map!

Thank-you for your support!


PS – because this is a video site and the post is about statistics, here is my TED Talk hero, Hans Rosling, spreading his good news of the decade:

Now go the the best website ever: GapMinder!

HIV and AIDS: Dangerous Denialism

You’d think the link between HIV and AIDS would by now be undisputed, but there is a growing amount of web and airtime being given to erroneous denialist views. Partly this is being stoked by the controversial ‘documentary’ House of Numbers:

Sadly, these views seem to be permeating mainstream media.

Guiding questions:

1. What are some of the main points made by the film?

2. What do they argue are the causes of AIDS?

3. What effects can glossy pseudo-scientific presentations such as this have on public perception and trust of science?



Brilliant (free) chapter on Matthias Rath and AIDS denialism in South Africa, from BadScience.


Here is MrT’s hero, Hans Rosling, outlining HIV/AIDS data using GapMinder:

1/4 Million Views on ScienceVideoResources!

Wow – 250,000 views and counting.

Looking at the stats, most people come here for the post on Eaten Alive: Parasites and the Body (over 8,000 views), with protein synthesis, our IB Biology course and cell respiration following closely behind. Thanks to everyone who has visited and left a comment so far!

If you like what you see, you can make a difference with Biology4Good. Also, please leave a comment and let me know where you’re from and what you use the site for.

To celebrate, here’s Hans Rosling, my favourite TED presenter and GapMinder master, sharing new facts, data and visuals on HIV – just in time for AIDS Day on the 1st December:

5.3 Populations

Essential Biology 5.3: Populations.

Try this tutorial from WHFreeman to see how how manipulating r (reproduction rate), No (starting population) and K (carrying capacity), affects the growth of a simulated population.

Yeast Population Growth lab and simulation:

You will need a copy of the IBDP Bio StatBook for the data collection.

You can also see how to use a hemacytometer to count the population of cells at JoVE.


Here’s MrT’s TED Talk hero Hans Rosling talking about global population growth, through the hi-tech medium of colourful bins. He argues that to curb population growth, we need to raise the living standards of the poor:

Key terms: population, carrying, capacity, exponential, lag, phase, plateau, natality, mortality, emigration, immigration.

Statistical Analysis 2009

Here is the updated presentation for 2009, with more information on Excel and a worked set of examples with hummingbirds, to tie in with the natural selection topics.
