How do trees move all that water all that way up? [Veritasium]
This is a great video from Derek at Veritasium on why and how trees are able to move water up 100m. It might not be the answer you think…

Hank blossoms with Plant Science
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.
King Corn – we are what we eat, drink and cook with
This film came out about a year ago, but I saw it for the first time on the History Channel a couple of days ago. A very enlightening view of the omnipresence of corn and corn-products in our food. From corn-fed beef to corn-starch and high-fructose corn syrup (boo!), industrial production of corn is in all facets of our diet.
In the film, two friends set out to produce an acre of corn and track how it grows and where is goes. Inspired by the Omnivore’s Dilemma and in tune with other recent super-docs (Super Size Me, Food Inc., The End of the Line), King Corn is a sensitive and educational film that manages not to stray into anti-industry polemic.
This extended clip from PBS shows the first 20-minutes of the movie:
It’s amazing to see that the corn farmers can’t even feed themselves with the corn they grow – it is not fit to be eaten! Instead it is bred and grown for maximum starch output. If you get a chance, watch it.
One impactful scene explains how high fructose corn syrup came to be and how it is made. Something to surely make you think twice about the contents of the processed foods we eat. Here’s a challenge – check the labels in the supermarket and see how may products contain it.
