hello

the best flask to use is a round bottom flask about 500ml-1l, please conact CLEAPSS or explore thier website if you need any health and safety advice or further pratical guidence on it.

Yours

Great video. You can make this quantitative for your students by measuring the distance of the first fringe from the centre and divide by the target-screen distance to get an angle. They can then calculate the spacing of the carbon atoms. They'll need some scaffolding; eg they need to work out the speed of the electrons from the accelerating voltage; then calculate the De Broglie wavelength and use the diffraction equation.

Have to say that I haven't found any better sequence to teach electricity & circuits and electromagnetic induction & transformers.  It would be nice to have access to the technician's guide and current suppliers for some of the bits & pieces needed.

These are really good clips that provide a problem in an everyday context. I have used the percentage problem and this gave my Year 6 a similar type of question as there might be in the SATs but in a much more interesting way! I also like the cat burglar problem for looking at properties of numbers and the scouts problem.

lovely little presentation ideal for ks2

Super useful for Medical Physics at AS or A2. Would also be useful for a high level GCSE group. The video produced lots of discussion.

I watched the video with my class and paused it to discuss bits of the presentation - they annotated the slides.

The worksheet is GCSE so I gave it to my A2 students to do in 5 mins!

Fantastic, this is perfect for my students, especially my vocational hairdressers, builders, tilers and so forth. Highly recommended!

These are excellent materials, useful for cross-disciplinary studies. There are clear elements shared with maths and music. With Computer Science also sharing these overlaps (with mandated components on repressntation of sound)  it is more than ever important that information across these subject boundaries  is not contradictory.

In the web page  text for "bubbles", it should read "sine wave", not "sign wave".

In the example of slowing down the wine glass, the changes are given firstly as half speed, and then five times slower. However this is not refleced in the pitch of the note. Halving speed should give a note one octave lower, whereas we get somewhat less - a minor seventh. Reduction of speed by a fifth should give a very much lower note - two octaves and a pure major third below - e.g. 1000Hz -->200Hz.  Whereas we get a minor ninth, only a tad slower than half-speed.

This therefore misses an opportunity to show how simply by listening to the change of pitch (to which the human ear is very sensitive), the change of speed can be estimated aurally to a high degree of accuracy – if one knows one's interval ratios!

A bit old fashioned for me, looked at the weight unit specifically - I've never heard of a hectogram so I had to look it up.

So glad to have found this.  I am sure i have a copy somewhere but was beginning to think i would never find it again.  These are great resources for revision at GCSE and KS3 - small, manageable tasks with immediate feedback to motivate even the hardest to reach students.  Levelled too - keeping everyone happy!

Am I missing something?  I note that although there are plenty of resources most of them appear to be now several years old - the date 2009 ie six years ago comes up regularly.

But my main question is about the Trust's organisation of the resources into their separate S-T-E-M components.  As an educator I am looking for resources that support an integrated PBL approach, whereby the otherwise separate subjects are seemlesly integrated, leading to single whole-day or half-day lessons.

When I trawl the Internet for STEM-based PBL resources I find that 95% of all contributions appear to come from the USA!

Please note that some earlier versions of Acrobat can cause some problems with viewing PDF files; however, re-installation of the software should fix the problem. Please contact me at resources@nationalstemcentre.org.uk if you have any further questions.

Kind regards,

Could you give any advice on how best to print the level sheet it seems to just come out blurry...?

Thank you for your comment. I have added the resource sheets we have available for books 4 and 5.
