My S+E teacher showed us the first 2 parts of 'How to grow a planet' and I was engaged the entire time, watching it even when we were allowed to talk with friends and play games simply because I found it so fascinating. The Scottish accent helps as well. ;). It is an amazing docu and I would recommend it to everyone. The way everything is explained so intricately is wonderful and gives a very detailed and informative show. The fact that the host even does an experiment during the film does not take away from the docu but enhances his point. The information about the bacteria that determined the colour of most plants and how the ocean used to be purple of all colours is extremely interesting. The way he explains it makes sure that most people can understand the jargon and not be completely lost.
