I think this might be a saccharimeter.  I checked both eyepieces using a piece of polaroid and each of them contains a polarising element.  The label on the base says “Griffin & George”. There is an extra label below this, that states “No.7709″.

Mr Mallon has kindly shared his Health Physics test for a bit of last minute Standard Grade Physics revision before the exam tomorrow.

Take the test.

Higher Physics on the move May 14, 2009

I’ve used some study leave time to complete the set of questions I said I would give you for your mobile phone.  From the class survey, it looks like 240 pixels wide by 320 pixels high is the ideal size for one of these.  There are 18 questions, “stolen” from some very old SQA multiple choice papers I found in a cupboard.  I’ve tweaked a couple of them to bring them up to date with the current course content.

To use the questions on your phone:

  1. hit the download icon below to get the attached zip file on to your computer
  2. unzip the file to reveal the jpg files inside
  3. send the files to the picture folder on your phone* by bluetooth or usb

*make sure your phone displays them in numerical order, i.e. Q0010.jpg, then Q0011.jpg, etc. - otherwise you’ll get the answer before the question!

I had to send the files individually by bluetooth because my bluetooth program reversed their order.  You might need to check which order your bluetooth or usb transfer uses & send them in the wrong order to get it right on your phone.  Ask me if you’re still not sure how to do this.

Here’s a sample question:
