GDST Guinness Book of World Records Science Practical

Posted: Physics

On Tuesday 13th November, 28 OHS girls took part in a huge science experiment involving over 2,000 students from the 26 GDST schools across the country as part of the GDST’s 140th anniversary celebrations.

The ever accurate and reliable (and amazing!) 7S measured acceleration due to gravity in their bid to help set the record for the world’s biggest practical science lesson in multiple venues.

They swung pendulums masquerading as yo-yos and dropped bean bags from the upper floor of our brilliant new library. Data was collected, entered onto spreadsheets and saved, and the whole process was kindly overseen by Dr. Amy Webber and Eleanor Grieveson from the Oxford University Department of Physics.

Our day ended with Davina Kourdi and Joana Baptista giving a splendid interview on BBC Radio Oxford’s DriveLive. Physics was never so much fun, and with luck, 7S will be part of GDST science history!

Year 8 Connected Curriculum D-Day

Posted: Maths

I am speaking to you from S3 in the maths block. This morning Mr Nicholl handed Year 8 the final note stating that unless he heard from them by registration this morning, that they were prepared at once to join him in his code breaking quest, a state of war would exist between the houses. I have to tell you now that no such undertaking was received and that consequently this year group is at war.

Tension was high as Year 8 battled ferociously with encryptions.  Houses clashed as rivals attempted to gain entrance to our secret lairs where mathematicians worked furiously, solving complicated Python problems. We plotted and planned and double bluffed, reliving the dilemmas that Britain would have faced when deciding where to invade occupied France. We endeavoured to produce fully functioning radios, with some people claiming to have succeeded in hearing Hitler’s broadcasts…

As D-Day loomed, we furiously crammed our brains with the knowledge we would need for the ultimate test. The test of all the skills we had amassed on this intensive training course. We could almost hear the bombs ringing out as we tramped back inside, our brains aching. Our suffering was insignificant in comparison to what the Allies would have endured when crossing the channel, knowing full well that they might never return.

Line upon line of soldiers dressed in real RAF suits, headscarves and bomber jackets marched proudly into the Lecture theatre for a speech from our General, Chris. He was very impressed with our war efforts and told us all about what it’s like to be more involved in code breaking at a higher level of expertise.

We fought valiantly and were victorious, a state of peace has now returned to Year 8. Never was so much owed by so many to so few, so thank you to all the teachers involved for making it such a memorable day!

“Physics in Action”

Posted: Physics

“Physics in Action” trip to University of London Institute of Education on Thursday November 25, 2010 was full of action indeed!

The Y13 and Y12 Physicists witnessed some very dramatic and entertaining demonstrations in a series of lectures presented by experts working at the frontiers of science. The students found out exciting things about the Sun in 3-D, were amazed by giant smoke rings, were enthralled by flaming music and more!

After the final laser light show in the lecture hall we had bracing walk across the West End to Covent Garden and then pizza. We made full use of the underground and surface rail network with an exciting rush hour journey through Central London and back home to Oxford. A good time was had by all.

Year 11 go (model) Flying!

Posted: Physics

Year 11 Physics had a great time testing rubber band-powered model airplanes this month.

As part of a unit on the physics of flight the girls in Mr Hypher’s classes took pioneering steps in various activities including wind tunnel studies of pressure distribution, lift and drag on a aerofoil. A flight-testing exercise of the rubber band models on the Sports Field yielded some astonishing free-flights. These included several of more than 10 seconds duration and 50 m range. One group even managed to get the Cessna model to take off from its wheels on the tennis court, fly to nearly the other end of the four courts and land safely! The radio-controlled electric-powered Super Cub is an exciting procurement of the Physics Department and has been seen in the skies of OHS performing flight training manoeuvres in preparation for flying demonstrations in the near future for all of Y11. Mrs Coulton’s classes are now working through the unit.

Engineering Club Aeronautics

Posted: Physics

The Engineering Club have begun working with rubber band-powered models and will be modifying them into multi-engined types in the hope of increasing their range and load-carrying ability. The recent acquisition of the electric-powered Super Cub will mean that there is the possibility of club members learning to fly it (under controlled and safe conditions) in the future. With Chief Pilot Mr Hypher at the controls the girls will be getting in-flight footage with a tiny camera as well as aerial drops!
