Assessed PGCE Demonstration

Discussion in 'Science' started by dsmithsci88, Mar 31, 2011.

  1. Hi all,

    I've got a 10 minute assessed PGCE demonstration coming up in May, basically all of the science mentors from the training centre get together to mark our demonstrating abilities.

    I've fired ideas around the department as to what I can do, I have a pharmaceutical background so specialise in chemistry and human biology but am still completely undecided as to what I could do. Being the awkward so and so that I am, I want to do something a bit different but still with a "Wow!" factor as well as complying with health & safety and a reasonable RA.

    I suppose I'm after something in the realms of screaming jelly baby (which I have done before) but we all know that's been done to death. Does anyone have any other cool ideas?

    Cheers.

    PS - I should mention that it should be tied into some actual learning as well!

    You could use the above floating disk expt to demo PHS. (Con't bother with the optional stuff - keep it simple). The disks sink when you replace the air in them with bicarb soln. As they Photosynthesise the oxygen displaces the bicarb and they float again. You can get a lot of high level questions in. Hope it works..
    Or catalase in liver, potatoes etc on hydrogen peroxide.
    Have fun

    just found this on the resources section
     
  4. Take care to plan HOW you present the demo as well as WHAT is in it. A good demo (in a classroom) is one where all pupils can actually see what is hapenning, they need to have some interest in the outcome (either having predicted or guessed what might happen & how - or be involved in assisting, advising, recording etc). In addition, they need to be able to ask questions and see the relevence or links to their work. Finally, they need to have some memory of it - so a worksheet or diagrams with notes are important.
    It sounds as if you may be doing this just for your assessors. If this is the case, give them a copy of the worksheet or notes & describe how you would set the stage for the demo in the classroom so that the pupils get 'ownership' of it & interest in it.
