Crash Course & SciShow Hanks’s last couple of videos have been on Plant Science: transport and reproduction. Head on over to the main Plant Science AHL page for the topic for the presentations and resources.
Felix Baumgartner is ready to jump! Follow the live feed below, or on the Red Bull Stratos website. His aim is to jump from the edge of space, breaking the sound barrier in freefall. Whoo!
Here’s a CGI simulation of what’s expected:
This full four-part HBO documentary series is online in full on the HBO Docs YouTube Channel. Although aimed at a US audience, the messages are universal. The website for the series has lots more related short clips and resources that might be of use in class.

Part 2: Choices
Part 3: Children in Crisis

Kudos to HBO for making this available on YouTube worldwide.
For what it’s worth, I think all TV production companies should be hosting their documentaries – especially those on important social and environmental issues – online for free. At the very least, make episodes available for a minimal ($1?) purchase fee on iTunes.
I bet most people wouldn’t choose to download media illegally if access was easy and affordable. It reminds me of this cartoon from the Oatmeal.
I was fortunate to meet Tom McFadden in Kyoto University yesterday, and have written up some thoughts on Educational Hip-Hop: Creativity and the Curriculum on i-Biology | Reflections.
Here’s Hank, giving a run-down of the fundamental forces. Might be useful for a flipclass intro or review for older students.
I haven’t posted Veritasium for a while, so here’s a great video building on his slinky drop experiments. Go full screen and HD, then wrap yer brain around the explanations.
Wow. Two papers published in Nature Methods have outlined a new technique which allows researchers to track development of embryos (in this case Drosophila melanogaster), in real time. By taking simulataneous multi-view microscopic images of the developing embryo, individual cells can be tracked in real time. The methods are described in more detail at Nature News here.
Have a look at the amazing results below, as a fruitfly embryo develops into a larva, ready to hatch. The two views are the dorsal (upper side) and ventral (lower side) view of the same embryo. See if you can pick a cell and watch its path of development.
Think about how this links to IB Biology topics of cell division, cell specialisation and embryonic development. How does a stem cell know what type of cell to become? If you look closely, there’s a scale bar in the bottom-right. Take a snapshot and calculate the actual length of the embryo.
