Bedales, biodiversity and lockdown

Biodiversity

By Cheryl Osborne, Teacher of Biology

Lockdown will be one of those defining moments. We will all remember where we were and what we were doing. For me, it will be the transition from standing in front of a class of children in my lab, to sitting staring at a computer screen on my sofa – an alien world and one that I am not enjoying! However, it hasn’t all been bad. The stillness and quiet has let nature be heard and during lockdown both Mary Shotter, our Biology technician, and I have immersed ourselves in it.

Mary has taken a biodiversity study of the Bedales site, and I have been taking photos of the wildflowers during my daily walks in the vicinity of Bedales. From these walks, I have put together some wildflower quizzes that have been available on the B-More Teams channel. I have really learnt a lot doing this and seen flowers that I hadn’t noticed before. My husband and I have been lucky, living close to school and the Ashford Hangers. The unnerving quiet of a deserted A3, which we walked over daily in those early days, allowed the birds and the rustling of the trees to be heard and heightened our awareness of nature all around.

Block 3 explore ecosystems for Ecology project

Ecology 1

By Cheryl Osborne, Teacher of Biology

In the five weeks before half term, Block 3 students were engaged in a project for Biology, researching an ecosystem. They chose their own ecosystems, which ranged from rainforests to cold deserts, coral reefs to wetlands. They were asked to identify three habitats within their ecosystem, to look at the biotic and abiotic factors affecting each habitat, and then finally to look at the adaptations of three organisms within each habitat.

The project enabled students to be independent in their learning and to be creative. They learnt research skills and the need to reference the websites that they used. Those who looked at the marking criteria carefully performed really well. The projects were presented as PowerPoints, word documents, posters and even a website (which can be accessed here).

6.1 biologists hear from leading scientists

Venki-Ramakrishnan

By Mary Shotter, Biology Technician

Biologists in 6.1 travelled to the Apollo Theatre in London to hear a series of lectures by some of the country’s leading scientists as part of A Level Biology Live.

First was 2009 Nobel Prize winner and President of the Royal Society, Professor Sir Venki Ramakrishnan (pictured above), whose many scientific contributions include his work on the atomic structure of ribosomes. Ribosomes exist in their millions in every cell, and are the site where genetic information is read to synthesise proteins from amino acids. He began work on ribosomes in the late 1970s and eventually discovered their complex three-dimensional structure in 2000, with the aid of X-ray crystallography.

Next, Professor Robert Winston – who was the Bedales Eckersley Lecture speaker in 2013 – spoke about manipulating human reproduction, from his work in vitro fertilisation, through to regenerative medicine such as stem cell research and epigenetics, which may turn out to be the most important biological development in the years to come. However, he warned that manipulating the human will always be dangerous, uncertain and unpredictable.
