Bedales scientists support Dunannie STEM event

By Liz Stacy, Head of Chemistry

Last Saturday was Bedales Pre-prep, Dunannie’s STEM themed Open Morning. Five of our Block 5 students – Rhiannon Griffith, Milo Whittle, Ben Bradberry, Mabel Watson and Athena Lucas – filled their lab coat pockets full of chocolates (the one and only time they will be allowed to put food in a lab coat!) and headed down to Dunannie to help the children with their science experiments.

There was an amazing range of experiments on offer, from making lava lamps using immiscible liquids and building circuits to power buzzers, to programming the Beebot robots to move and light up on command and looking at field line patterns using magnets. The students were tasked with judging each exhibit on presentation and also the scientific knowledge of the children manning the experiment. They also fielded questions from prospective parents about what studying at Bedales was like and the excellent opportunities on offer for students interested in pursuing science. I thought Milo was maybe a bit harsh giving one small six-year-old five out of ten for scientific knowledge – he did award a lot of chocolate though!

Bedales Physicists visit CERN, Geneva

CERN-trip

By Anthony White, 6.2 and Physics Don

On 24 January, 6.2 Physics students were fortunate enough to travel to the largest laboratory for particle research to date – the Conseil Européen Pour La Recherche Nucléaire (CERN) in Geneva. It provides physicists with the ability to accelerate particles to approximately 1.08 billion kilometres per hour, while then observing the results of their collisions.

The first day saw us visiting the Red Cross Museum, an exhibition dedicated to the international humanitarian organisation that brings relief to people in the event of war or natural disaster. In the evening, we visited the History of Science Museum in Lake Side Park. On display were over 800 instruments, mainly used by Swiss scientists, dating back to the 17th century.

Biodiversity at Bedales

Bedales-estate

By Mary Shotter, Biology technician

Over the past few weeks, in collaboration with a group of Block 3 Outdoor Work students and the Sustainability Group, we have begun the huge task of cataloguing the school’s biodiversity.

We started with the Lake, where we discovered 28 different species of freshwater animals, including water boatmen, dragonfly and damselfly nymphs, whirlgig beetles and flatworms. A walk around the centre of the site revealed 38 species of tree and 19 birds, such as the green woodpecker and nuthatch. The use of a moth trap also showed there were 14 moth species in the wildlife garden behind the Science department, which is remarkable, considering it is late in the year.

Sixth Form physicists visit the Joint European Torus

By Tobias Hardy, Head of Physics

To fend off the global warming crisis, we need to appeal to the hottest place on earth. The sun’s core is 10 million degrees, but in the Joint European Torus (JET) at Culham, the doughnut-shaped plasma in the reactor consistently reaches temperatures of over 100 million degrees to initiate nuclear fusion between hydrogen isotopes and release enormous quantities of energy. The hydrogen is sourced from seawater, and there are no harmful waste products. What is not to like? Unfortunately, it’s fiendishly difficult to achieve.

The Sixth Form physicists visited JET last week, for an inspiring tour and lectures. The scientists and engineers explained the current developments of this futuristic technology, which has come a long way since its inception in 1983, and has inspired the next generation of fusion reactors, driving the plasma science and fusion research. Ground-breaking and innovative engineering solutions are necessary for the magnetic containment, keeping the super-heated plasma just metres from the surrounding vacuum at almost zero, to harness this potentially limitless resource.

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.
