Yr 12 bio brac exams

[Sassi]

Hi everyone,

We have done the capsicum enzyme prac for a number of years now (according to the teachers since I have only been here a yr) and they would like to do something different for once, but it seems they have run dry of ideas... So I thought id ask you guys, what do you do for your yr 12 bio prac exams???

No way, gross! We wanted to do something other than an enzyme prac exam anyways, but thanks for your, erhm, suggestion

Hi Sassi,

The attachment is a prac we did at a school I used to work at and it worked well.
