Here’s another video that might come in useful when teaching about acids and alkalis – Rosie Coates shows us her favourite chemistry demonstration involving a giant test-tube and some universal indicator solution. As well as showing us a fantastic demo, Rosie explains how the science of acids and alkalis can have important real-world applications. This is another video where it’s really worth hitting the “HQ” button on the youtube player after you’ve hit “play”.
I’ve already blogged about climate change videos but wanted to post this film by Leo Murray separately because it really is in a class of its own. It’s a beautifully animated, thought-provoking film, and one which I think students will enjoy watching. You can find the HD version here. There is some good science in the film, with clear explanations of mechanisms that cause climate change and of how we might reach a “tipping point”. (Leo provides a copy of the script, including references here.) However, it is an unashamedly… Read more Wake Up, Freak Out – then Get a Grip →

An Inconvenient Truth is just too long for use in class and, frankly, just too boring. Al Gore’s film is worthy but dull and really only suitable for use if you’ve not bothered to plan your lesson or if you want to send a particularly… Read more An Inconvenient Truth – Al Gore’s film is not very good. →
