Year 12 CERN 360 Images

Come and join us with the latest photos from our annual Y12 trip to CERN. The students had the opportunity to meet and ask key questions of CERN scientists whilst we visited the ATLAS site and the Super Conductor Test Facility. The students found it extremely valuable and it will enhance their curriculum knowledge by embedding them in a rich contextual experience.

We invite you to join us with what they saw thanks to our new 360 camera. Check out the gallery as we toured Lake Geneva, Mont-Saleve, and CERN! In addition there is a 360 video of the cloud chamber that they have in the CERN museum, we will use this as a teaching tool in lessons to allow students to view cosmic rays.

Particle Physics Masterclass at Rutherford Appleton Laboratory

particle physics 01

Year 12 and 13 students have been experiencing experimental physics first hand at the Particle Physics Masterclass. Held at the Rutherford Appleton Laboratory in Oxford, we visited the ISIS neutron and muon source, the largest particle accelerator in the UK, to learn about cutting edge research first hand.

Students were able to visit the collider where amazing feats of engineering are happening every day to create subatomic particles and look at data transmitted from CERN to find the Higgs boson, with APS proving their scientific credentials as the first school at the workshop to identify evidence of a Higgs event. The day was rounded off by a series of engaging and stimulating lectures that are sure to inspire our physicists of the future. Here are their thoughts on the day:

The talks were very interesting and well structured around the other activities of the day which provided a great insight into the uses and what is involved in running a particle accelerator. I was also inspiring to see the the wide range of careers and people that work there.Cosmo
The visit to the accelerator was very well structured. We listened to talks about particle physics, the history of particle accelerators and how they work, all of which were interesting and informative. We also had a tour of some of the facility, where we learnt more about the work involved in operating accelerators, and got the chance to use a computer program that allowed us to view data from the LHC. Overall, the day was inspiring and insightful.Max
The activities allowed us to gain a better insight into data processing and the structure of the data collectors at CERN. We learnt a lot about the different detectors and how they are used to understand which fundamental particles are given off during a collision and how momentum is conseved. The tour also allowed us the see how much effort goes into building all the machinery needed to carry out the research.Granit
The trip was very interesting and was extremely helpful in widening my knowledge in physics. Additionally, it helped me understand further possible careers in physics. The layout of the day was also well structured. Furthermore, I found it extraordinary witnessing the amazing apparatus used in particle accelerators.Alexandros Androutsos
The trip to the accelerator was very interesting and insightful onto the physics and process behind finding new sub atomic particles that could help us understand the world better . The talks were interesting and expanded my knowledge on quantum physics and therefore giving me a heads start on others . I also went to ISIS which showed me their machinery close up and gave me a visual idea of how much is needed to control sub atomic particles and their interactions.Viktor Maszewski

APS Astronomy Evening huge success

On Valentine's day 2019, Alexandra Park School's science department fell in love with the stars as we hosted an evening of astronomy.

Steve Fossey of UCL and the Mill Hill observatory kicked the evening off with a fascinating retelling of the night he and his team discovered a supernova, which was followed by 2 hours of observing the night sky through the school's telescopes. Highlights of the evening included the STEAM club's homemade telescopes giving clear and highly magnified images of the Moon's surface, and a breath-taking view of the Orion nebula through the school's larger refracting telescope thanks to the fortuitous weather.

I've never used a telescope before! It was interesting to see stars from a different perspective, and Ill never forget itEddie
It was goodCharlie
I went to the Astronomy Observation evening thinking it would be a waste of time (in the cold!) but then I found out that it was really cool and fun!Elsie, 7A
I have never seen the moon that close up before! It was so detailed!>Marin, 7X
I thought fun and interesting to learn about astronomy and see the stars and the moon through a telescope I also found it very interesting when Steve Fossey was talking about supernovasAmelia, 7A
It was extremely enjoyable to learn about supernovas and how they start and end. I also enjoyed using the telescopes we made to see the stars (even if it was quite difficult)Bethany, 7L

APS Hosts International Erasmus Project

erasmus logo

From 3rd to 11th November 2018 APS had the pleasure of hosting for the 3rd week-long student meeting of our Erasmus+ project looking at Alternative energy and Energy storage. The aim of the two year project is to enlighten students from the 4 partner countries, Greece, Denmark, Poland and the UK about issues around switching our electricity supply to renewables such as wind and solar; great when the wind's blowing or the sun is shining but less good when they're not! Hence, the need for large-scale energy storage and clever technology that matches supply and demand. Over the course of the two years, delegations of 15-19 year old students from every partner school meet in each of the countries to attend visits and talks from experts and work in international groups.

As a world-leading city, it was no surprise we had a busy week indulging in both the science of the project and the equally important cultural side. We must thank the generous staff who organised excellent visits to the Cavendish labs at Cambridge University, Imperial College London and UCL. The group had the privilege of a guided tour of a science museum gallery by the galleries curators! We also had a number of STEM ambassadors and industry experts come into school to work with the group. On the cultural side as well as time exploring central London, the students and staff had a social evening at the legendary Rowans bowling in Finsbury Park and helped during sixth form open evening, running stands in languages and science.

All of the students both visiting and our own demonstrated model behaviour and great enthusiasm for international working and solving the challenging area of having a cleaner electrical energy supply. They now return to their own school and community to spread this knowledge and enthusiasm.

A very big thank you to the APS host families who had international students stay with them and to all involved in the project. We now look forward to the final project meeting on the Greek island of Kos in April 2019 and further ahead to where the students working on this project become future scientists and engineers in a global marketplace solving complex problems and making the world energy supply more sustainable!

Students had a lot of positive comments about the week's activities:

Guided tour by the curator of the Mathematics gallery at London's Science Museum

The mathematics exhibition was great, it was interesting listening to Natasha and Rachel (curators) why and how specific exhibits are chosen. They were so informative it was a real eye opener.Celia
The science museum was huge. We heard lots about the different computers and medical exhibits..I had a great time.Hamze (Danish student)
Who knew Florence Nightingale had such an important role in medical data collection. What an informative and interesting trip around the exhibition.Ash

Visit to Cambridge University's Canvendish laboratories and museum

A fascinating talk about energy storage and the problems with this. It was especially interesting to hear about 'load levelling' to cope with varying levels of energy production from sustainable sources such as solar power, and the different types of batteries that can be used to achieve this. It was also interesting to hear about the way batteries and such can be analysed, using a graph to compare the specific energy and specific power of batteries - for example, lithium ion batteries have a high specific energy but a low specific power, and vice versa for capacitors.
We also learnt about the problems with lithium ions batteries - lithium is limited, cobalt and nickel can be toxic in the environment, so disposal is a problem. Hydrogen fuel cells can be used instead, although hydrogen gas can be difficult to work with so the system must be made safer before it can be considered a viable alternative. Celia
  • brief explanation of the band gap within atoms where electrons jump from the valence to the conductive band when energised, and as they drop down to the relaxed state they emit a photon. It is the size of this band gap that influences the ability of the material to release a photon. 
  • learnt about the processes involved in the manufacture of flexible solar panels, such as spinning the substrate with the active layer material added at incredibly high speeds, or printing, in order to get layers as thin as 100nm.
  • introduced to the idea of perovskites, materials with an ABX3 structure, where A is an organic molecule eg carbon and X is a halide such as chlorine, which have an ideal band gap to be used as an active layer. These allow the solar panel to be both flexible and so thin that they are almost transparent, which could give rise to possible applications in buildings e.g windows.
  • Solar thermal fields are an option when temperature is too high for photovoltaics to operate efficiently such as in the desert - using mirrors to focus light onto salt plains that then melt - as the molten salt cools, the energy can be used without worrying about fitting photovoltaics with cooling systems or replacing the materials as they degrade/melt due to the heat, saving labour, cost and materials.
  • linking with the problem of energy storage - electricity from solar power needs to be stored in batteries that must be affordable, safe, use non-toxic materials, and must be able to cope with higher energy quantities in peak times. Losses from the grid are around 20%, so there is a need to optimise this infrastructure, possibly using a 'borrowing and lending' system where energy is sold between areas of excess and deficit, or superconducting wires to avoid losses if these are developed to a point where they are affordable enough to be a feasible options. Countries that may not be as industry heavy may be a better option for photovoltaic energy because they do not need as large or constant a supply of electricity.
  • difficulty with implementing renewable energy sources such as photovoltaic technology due to the high cost of such when compared the the relatively cheap energy sources that are available to the country, regardless of the effect on the environment, such as Poland with their intensive use of coal due to the abundance of it in the country. Suggests a need for an economic intervention / programs that allow countries to set up the infrastructure for more renewable energy sources without the country having to independently fund such an endeavour.
I thought that the lecture was particularly interesting and pushed us to understand the complicated science behind it all.Marionette

Imperial College London

Listening to the different speakers was really interesting as they all had different approaches to the topic. Following the talks, we got a chance to witness a Li-ion battery charge, and we were able to calculate the charge of it using equations ourselves.Eridona, Alicem and Said
