Reactivity of Metals

Watching sodium being put into water is one of the few things that everyone seems to remember from school science lessons. I would encourage all science teachers do do as much as they can “for real” when it comes to teaching the “reactivity of metals”. If for some reason, there are some experiments you can’t do in school, there are some videos from the Royal Society of Chemistry that you might find useful. There are also a wealth of such videos on youtube, if you are prepared to spend the… Read more Reactivity of Metals

Virtual Experiments

Here’s a great free resource that allows students to practice data collection and other aspects of experimental science without the hassle of actually doing the experiment. Before you start screaming about how it’s important to do these things for real, this is what the makers of this resource say: “Virtual Experiments are not intended to replace the real hands-on laboratory – science students need to develop the skills of setting up, alignment and adjustment with real equipment – but they can offer huge added value as warm-ups to the real thing,… Read more Virtual Experiments

Black History Month

October is Black History Month in the UK. I’d bet most science teachers would struggle to name a single black scientist from history. Whilst it may be important to make students aware of the historical contributions of black scientists, I think it’s perhaps more important to make children aware of the work that black scientists are doing today, particularly in Africa. The film below is one I made back in 2006. It is a portrait of the winner of the 2006 Royal Society Pfizer Award – for “an outstanding, innovative… Read more Black History Month

The Whitest Substance on Earth

This is one for you if you’re feeling a little lazy. You could do this demo and explain the science yourself… or you can let Dr Andrea Sella of the UCL Chemistry Department explain why things appear “white”. Suitable for anyone teaching the electromagnetic spectrum or “properties of light” at KS3 or KS4. (Warning: the first few seconds of the video are deliberately meant to show a blank white screen).

Rosie and the amazing technicolour test-tube

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”.

Acid Spraying Ants

I love teaching about acids and alkalis at KS3 because there’s quite a bit of fun practical work you can do – making an indicator out of red cabbage is an activity that Year 7 always seem to love. The textbook way of starting this topic is to talk about about acids and alkalis around the house… but this might be far more dramatic / interesting way to introduce the subject: The clip is from Smalltalk Diaries, a series of ten short shows about the lives of minibeasts.

An Inconvenient Truth – Al Gore’s film is not very good.

I imagine every school in the country has got at least one copy of An Inconvenient Truth lying around somewhere, but, in my opinion, there are better free films out there for teachers wanting some kind of video resource to help teach about climate change. 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.
