There are now quite a few resources for teaching chemistry uploaded onto our website.They are linked to, where possible, from all the appropriate outcomes at the various curricular levels. In addition, they can be browsed en masse from the pages below.
Previously the resources were arranged into workshops, demonstrations or ‘other chemistry experiments’. This is not particularly helpful if you don’t know what group an experiment is in so they are now in a single alphabetical list – there will also be an index coming soon to help you locate the experiment you want.
The only form of separation is that the microscale activities are on their own page with tabs for the experiments, equipment making etc.
In order to give a bit of guidance as to usage, in the summaries we have used the following suffixes (c) for a classroom experiment (d) for a demonstration and (i) where we think it is suitable for investigative work. We also make suggestions as to the age groups they are suitable for. As always, though, these are merely suggestions: use them as you will.

Here is a list of links to some websites that provide ideas and support for practical chemistry.
Please remember – while this is a list of reputable sites and you can be pretty sure that their experiments are safe and reliable, they have been drawn up in different jurisdictions with different regulations You will need to carry out your own risk assessments before using them in the classroom.
Many of the experiments from English websites make reference to CLEAPSS Hazcards for health and safety information. Here in Scotland, you can just visit the relevant page on the Hazardous Chemicals section of the Website for the same information.
All the links will open in new windows so you don’t need to log back in to our site.
Royal Society of Chemistry – All the RSC’s experiment protocols and much, much more can be found in the new Learn Chemistry part of their wenbsite. It can be a bit tricky to find what you want but it is almost certainly there.
Nuffield Foundation – This is in association with the RSC so there will be some overlap. The Practical Chemistry’ section of the site is the bit with all the resources.
STEM Learning – This is a link to their elibrary which covers all the STEM subjects. There is an easy to use set of filters to help you find what you want. You do need to register for this one but it is free.
The Solar Spark – A site run, at least in part, by Neil Robertson’s group at Edinburgh University, who research Dye Sensitised Solar Cells. You will find experiments using DSSCs there but quite a bit more as well.
Edinburgh University Chemistry Department – a site set up by the University of Edinburgh Chemistry Department. This link takes you directly to the experiments but elsewhere on the site it explains how you can get people to come out to you for workshops.
Bob Worley’s Microscale Chemistry site – A treasure trove of great ideas for microscale chemistry.
NurdRage – One of the best of the YouTube channels dealing with chemistry. A lot of interesting practical work: some of it not suitable but quite a few readily manageable experiments.
Periodic videos – a tremendous resource with videos on every element in the periodic table.
Chemistry Map of Scotland – A google map of lots of chemistry-related sites across Scotland.
A while back, I set about collecting information about locations in Scotland with some connection to chemistry and put them on a Google map. There are three layers on the map: birth, death and memorial sites, sites relating to education, and sites relating to industry. This is inevitably incomplete, so if any of you know of any I have missed out, please let me know.
TWIGonGLOW – This is a good selection of videos to support teaching, targeted at CfE levels 2,3 and 4. It is part of GLOW so you will need to sign in to access them.
