Biology

Year 11 Biology

We consider biology to be a fundamentally essential subject in the understanding of the world around us. Biology teaches us about ourselves and the world we live in including what we need to protect and preserve not only our life but the life of all organisms living on planet Earth.  Lessons are taught with a practical bias looking at finding out why things happen, allowing the boys to discover for themselves but then backing this up with the theory to gain a complete understanding of each of the topic areas covered.

Facilities

We have a bespoke Biology laboratory. Our lessons are practically based with specialist teachers of each of the science disciplines.
