Junior Cert Science Investigations 2010/2011

Anyone have any ideas or suggestions for how to go about doing the Biology Investigation?

Carry out an investigation to study the anerobic respiration of yeast with particular reference to (i) the change of temperature with time, (ii) the evolution of carbon dioxide with time and (iii) the change of density with time.

We're not starting our experiments until after Christmas, possibly after the Pres.

We're doing the Chemistry and Physics experiments.

Physics: Linky;)

ok well were doing the physics and the biology ones
for biology my teacher explained to us how to do it, sorta lol
lemmie know if u want some help

Anyone have any tips for the chemistry one?

I've done my chemistry and physics now, in the process of filling out the booklet. There's only 2 groups in my year doing the bio one this year, not very popular. ;o

Cakes.

We're not doing ours till after the pres... I don't think she even knows what the experiments are :pac:

I'm doing Biology for the Leaving Cert and there's an experiment called "to prepare and show the production of alcohol by yeast", this could be help you for the experiment so if you can get your hands on a Leaving Cert Biology book have a look at that.

Just do the one everyone else is doing. They say you're supposed to be different but its not really true.

We're doing the Physics and Chemistry experiments. Apparently, they make the Physics experiment easy because many people don't take Physics for the Leaving Cert because of the perceived difficulty.

We were going to wait until after the Pres to start them, but we will probably do one before the Pres, just to make sure we're not under too much pressure afterwards.

We're starting our Physics experiment tomorrow. My teacher will freak if I don't have some research done.

I'll just find out what affects friction or something easy to keep her happy.

Anyone finished any experiments yet?

yeahh i have, we finished writing the physics one into the official booklet thingy today
such a relief
doing the biology one next week
