    Was thinking a short practical comparing different metals an dtheory behind it......
     
  2. How long have you got? What ability?
    Metals and acids is a nice easy practical.

    1 hour lesson
    As you are aware I am keen to gain a good, I am willing to try new things and take a risk, this class has good behaviour and level 5-6 targets.

    I can either begin the chemical reactions topic on the observation lesson- i.e chemical reactions v physical changes or do metals and acid recations.I can start the topic either when I go back or for my observation, I have a filler lesson if needed...

    Either area I can start on/.
     
  4. If it were me (which it isn't!) I would focus on investigative skills. How can the reaction be measured (compare qualitative and quantitative results)? What do the results tell us? What don't they tell us? How could the investigation be extended? Get them thinking/discussing and a less teacher led lesson.
     
  5. After the practical work, however you want to run it, I'd strongly recommend something hands-on to show the reactions. Printing 8 to an A4 page means you could 'build' the molecules and show the rearrangements (holepunch each card and link with treasury tags). Molymods are of course also useful but if your kids are anythign like mine, you'll find many alien sculptures and few molecules.
