Year 11 biologists zone in on antimicrobial activity.

Year 11 biologists completed their last required GCSE biology practical investigation looking at the effect of various antibiotics on bacteria.

As part of the GCSE Biology course, Year 11 Biologists investigated the effect of antibiotics on the growth bacterial cultures using aseptic techniques. GCSE Biology specification Students safely spread bacteria on an agar plate, added discs soaked in antibiotics, incubated their bacterial ‘plates’ overnight and then measured the ‘zone of inhibition’. This is the area where the antibiotics have successfully killed the bacteria, it shows up as a clear area around the antibiotic discs. They achieved superb results and this was a great way to complete their last required practical for their biology GCSE.
