I used to ask students to read about Biology outside the classroom, and I've even subscribed to magazines and loaned them to students to encourage this reading. In today's world students are much more likely to watch a short video than to read a magazine article, so why not make use of this.

Fortunately there are many channels on YouTube channel with great biology stories, and

One of my favourites, Journey to the Microcosmos is full of fantastic entertaining microscope imagery and a great narration which reminds me of Carl Sagan and covers many areas of DP Biology.

Here is an example:

The Science Communication Lab uses high-quality documentary film making to explore the nature of science, the stories of scientists, and the broader implications for society. This organisation has several different YouTube channels, including;

1. Wonderlab attempts to bring innovative storytellers and the global scientific community together in a spirit of experimentation and collaboration to revolutionize science film making with the wonder, awe, and diversity of discovery
2. iBiology channel contains biology talks by the world's leading scientists that show the process of science and the wonders of discovery.

Quanta magazine also has some fabulous short video explanations. It is an award-winning, editorially independent magazine published by the Simons Foundation. http://www.quantamagazine.org/
