Really like these. Great for consolidation and there are numerous opportunities for differentiation.

Hello Mary,

I'll contact the resource provider and I'll ask them for another copy of the resource together with the teacher's notes.

Regards,

Anna

This template is to make two discs, but the repeat instructions carry on the numbering. Poorly drawn disc.

There is no teacher guidance to explain how the activity 'illustrates how the eye works'.

Disappointing.

Some good experiments for testing the senses, some that I had forgotten about.

These websites seem really interesting and a good starting point for discussions. However, it appears they are unfinished, with broken links and missing features (e.g. the Your Shout! section).  Will these be finished soon or was this project abandoned?

I've used this as a summary activity for my set 1, 2 and 3 year 11s - they worked on laptops in pairs and used this as part of their revision.  It worked well and covers most of the areas in the AQA Additional Science GCSE enzymes topic.  The students found it easy to use and a useful revision tool.

Brilliant : cheap readily available materials : effective but simple demonstration of the Physics

Yes, it is a real experiment - I shot the video (all of the videos in S&S are actual experiments, conducted in a 'normal' lab). The bag is full of pure oxygen (collected from decomposing hydrogen peroxide with manganese dioxide catalyst) - enough to react with all of the magnesium. However inside the test-tube is just air - that way there isn't much, if at all, reduction in the overall pressure inside the apparatus as the reaction proceeds. I also cleaned the surface of the magnesium ribbon - to make it look nicer but that might also have helped with the initial reaction.   It might be worth checking your apparatus for 'air tightness' - any breaches and air will be drawn in rather than the bag collapsing - sometimes a hole develops in the test-tube as the glass softens during the reaction.

As noted by Anna, the expectation that you carry out your own risk assessment applies.

Thank you for very useful resources for the teaching of materials.

Hello,

The video clips are not supposed to be included as part of this resource. The description mentions that it is the lesson outline (teachers' notes) which includes the links to the video clips.

Hello,

Thank you for raising this. Although all the demonstrations on the package show results of actual experiments, they would not all be suitable to be carried out in a school setting. We appreciate that you will carry out your own risk assessment for any activity in school, but there is generic guidance on health and safety here http://www.nationalstemcentre.org.uk/elibrary/health-and-safety, which you may find useful.
