Science Rocks UK at Imperial College

Jess Wade, a final year PhD student at Imperial College and Postgraduate Representative of the Women in Physics Society gave me the opportunity of a lifetime! It was the best day I have ever had at Imperial. I was lucky enough to meet the Science Rocks UK girls, who are two wonderful and inspirational girls, Elizabeth and Megan O'Shea, that promote science through their website in the form of videos and articles. Being year 10 students I was amazed by their sheer enthusiasm to promote science. The world definitely needs more girls like them in order to encourage other girls to enter the brilliant world of STEM! Check out their cool website here.

To my surprise I had met them before! Back in March 2013 at the Big Bang Fair where I was exhibiting my Nuffield Science Project carried out at Imperial College in the National Science and Engineering Competition. The girls and their wonderful parents had visited my stand at the fair and it was an absolute pleasure to meet them again.

The girls had a jam-packed day organised by the legend, Jess Wade at Imperial College. The girls had a wonderful tour of Imperial College, followed by a STEM Potential Course at the Reach Out Lab and a Maths lecture which filled their morning. After lunch the fun continued with a video interview with my favourite Vector Calculus lecturer, Professor Schwartz who gave the girls a great insight into space physics.

The fun factor really escalated with Dr. Simon Foster, Outreach superstar, who showed the girls a 'supercool' demo with a superconductor (YBCO) that had to be supercooled with liquid nitrogen. This was levitated on a magnet track (using neodymium magnets) since the superconductor, in a way, expels magnetic fields. It was the coolest thing I had ever seen and the girls loved it too!

The girls also had a chance to interview two postgraduates about their work before taking 325 steps to the top of the Queen's Tower on campus. The views were exquisite and the girls had a great time taking pictures of the picturesque views! The tour was topped off with a chance to see inside the research environment created by Norman Foster to encourage discussion between groups - the colour gradient of the walls was an added perk.

The day ended on a high with a jaw-dropping tour of the medical robotics group at the Hamlyn Centre courtesy of Felicity McGrath, Neil Clancy and Petros Giataganas. The most advanced medical robots were shown to us as well as five 3D printers - these 3D printer could print with different densities, colours and a variety of moveable one pieces could be printed! I was amazed! I've always been a fan of medical physics but this day made me want to get into medical physics right now!

Here are some highlights of the day:

UK Space Design Competition

I got the privilege to accompany a group of A level students in the semi-final of the UK Space Design Competition. Their brilliant video entry (which was all their independent work), won them a place at the semi-finals. The competition was fierce and it was a huge achievement for these talented students to get to the semi-finals of a national competition! The competition is designed to allow students to experience life in industry. Teams are given a set of requirements for a space settlement and are given 24 hours to design their space settlement before displaying their ideas to a panel of experts. The residential competition was held at Imperial College and a chance to earn a place at the international finals at a NASA Space Center was up for grabs!

The students were, Mokrane Berboucha of Lampton School, Roshan Hansla of Heathlands School and Leon Seeamber and Parus Kargathra of Heston Community School.

The first day of the competition involved twenty hours of solid research and hard work in designing a space settlement. The students were working with around 45 other students from various other schools for a company group named Grumbo Aerospace, thus communication was vital. The other company groups were: Vulture Aviation, Rockdonnell, Dougeldyne Fletchel.


After 20+ hours of research, Grumbo Aerospace was ready to present in front of the judges which included: Anita Gale, an Associate Technical Fellow and senior project engineer at Boeing; Jeremy Curtis, Head of Education at the UK Space Agency; Dr Randall Perry, founder of the UKSDC and a senior research investigator at the Impacts and Astromaterials Research Centre at Imperial College London; and Helen Oliver, a research associate at the University of Cambridge Computer Laboratory.



The competition was high and Grumbo Aerospace just fell short of winning, earning themselves second place in the UKSDC National Final. This was no small feat and the students should be very proud of themselves and their achievement! They even got to go away with a snazzy certificate and a brain full of space knowledge!

Science Challenge: Imperial College


Back in January I decided to enter the Science Challenge, which is 'the Royal College of Science Union's annual science communication competition. Requiring entrants to demonstrate their skills in scientific debate and reasoning, the Science Challenge tests the ability of today's young scientists to teach the public about the science that affects their lives.'
Not only can Imperial students enter but schools can too! So why not enter next year! Communicate your enthusiasm for Science and if you're lucky you may even be rewarded for it - previous years have had trips to CERN! Make sure you don't miss out!

Although I didn't get into the finals, I managed to get to the quarter-finals with the following essay: 

"How do we get the next generation interested in STEM (Science, Technology, Engineering, Medicine)?" Answer this question via an essay, maximum 800 words.

The next generation are the future so in order to get them interested in STEM we must get them while they are young. Let’s just take a look at what is in toy stores. In the girls aisle we see a blur of different shades of pink, we focus onto the items and we begin to see tutus and dolls. On the other hand the boys’ aisle is a blur of blue which turns out to be construction toys which help develop their skills, like logic, problem solving and creative thinking. Shouldn't girls be able to play with such skill-enriching toys? If we are going to try and get the next generation interested in STEM this is the place to start.

Taking the young to planetariums, hands-on workshops and live events to see science in front of their eyes is a great way to stimulate their interest but the key thing here is maintaining that interest. As they grow they may start to outgrow the ‘family outings’ and begin to wander into the Universe on their own – how do we keep them interested in STEM? We tell them that STEM needs them, that they are a young, curious mind that could help unravel the mysteries of our cosmos. One major way we can do this is by getting them involved with real science. Whether that is participating in identifying cancer cells, counting birds or controlling an experiment online they can see and do real science at their fingertips. Make STEM something that can be done at home – using everyday objects to uncover the delightful surprises that STEM has to offer. Science shows like The Royal Institution Christmas lectures where the whole family can get involved and do science at home should be something that we see more on TV.

So we can try and get the young ones but what’s to stop the parents from telling them that STEM is too hard or what can you possibly do with STEM? We need to educate the parents and let them know about the myriad of opportunities available to their children via STEM. This can be done by advertising – having little fact files about, say, how much the engineer who helped design a building earns, what they do and what degree is required which could be displayed somewhere on the building or in the vicinity. Even larger advertising endeavours could include bus shelters, billboards and public transport where posters about job profiles displayed in a modern way through artistic means could be put up. Even just cool STEM facts or STEM teasers to grab a reader to learn more through a link that may be displayed on the poster to engage the public, including the next generation into STEM.

But let’s take a step into the classroom. This is where those young minds first encounter STEM via academic means and this is where they decide if they want to take STEM further. Classrooms sometimes lack enthusiastic teachers, stimulating demonstrations and real STEMists (a scientist, technologist, engineer or medic). Now, of course we cannot make it compulsory for teachers to be enthusiastic but we can bring real STEMists in. Where the STEMist should not throw facts at the students but should instead spark their interest, whether this is via a hands-on experiment, a group project or through trips to real laboratories, observatories and other STEM landmarks that would get them engaged in STEM. The students need to be able to see that STEM has a purpose in their life and that with STEM they can truly change the world - they are the ones that shall sculpt the future.

In particular, a STEMist who was an ex-student of the school would have a larger impact on the students as they used to sit in the same classroom seats as the current students. They can relate to them on a different level and truly believe that they have the capability to follow in their footsteps and be successful in STEM. More importantly, bringing undergraduates who were also ex-students into the school could relate to the students even more as they are roughly the same age and they can share their experiences and knowledge about the wonders of STEM.

All in all, STEM needs to be approachable and the stereotype of STEM being hard and boring needs to be eradicated via interaction with the next generation through the methods aforementioned; hopefully this is the way forward for a STEM rich future!

Women in Physics Imperial College


Women physicists at Imperial College now have a new community, from undergraduate to Professor-level, where they can support and encourage other females to remain in physics. 

Courtesy of Jess Wade, a PhD student currently in her final year at Imperial College, two Women in Physics events were held this week at Imperial College in celebration of International Women's Day: a postgraduate and undergraduate lunch.

We had a great turnout and I even got a chance to speak to the postgraduates and undergraduates at the lunches explaining how WiP (Women in Physics) could help undergraduates like myself. It was great to see so many female physicists at Imperial - something that I don't see in lectures, labs or tutorials.

There are so many schemes out there for secondary students to take Physics but once at university I felt there was no encouragement or inspiration for females to remain in Physics and there was no connection between the years. But now with WiP we hope the future will be bright and more females shall have a longer Physics path!

Here are a few pictures from the postgraduate and undergraduate lunch:

Electrostatic Slime - Science you can do at home!


See how a balloon can stop a substance from being poured with just a balloon, cornstarch and vegetable oil! All things that you can find at home, so go on grab some vegetable oil and cornstarch from the cupboard and a balloon from your last birthday party (or make a quick trip to your nearest supermarket) and get ready for some sciency fun!

Mix equal amounts of vegetable oil and cornstarch powder into a cup - so if you put a quarter of a cup of vegetable oil then you need a quarter of a cup of cornstarch powder added to this. Then stir with a spoon and that's it! You've made your electrostatic slime!

Now grab that party balloon and rub it in your hair or a woolly jumper - you've now charged the balloon (more science talk is on its way). Now start to pour your slime into another cup and then bring the balloon near the slime and watch it get attracted towards the balloon and you may even see it stop pouring! 

Here's some successful electrostatic slime:



Slimey Science

When you rub the balloon in your hair or against your woolly jumper electrons from your hair/jumper are rubbed off onto the balloon by friction. Thus, the balloon gains a negative charge and your hair becomes positively charged and you know that like charges repel and opposite charges attract - this is why your hair suddenly becomes attracted to the balloon! 

But how does the slime get attracted to the balloon without touching it?! Well, what we have made is a substance where the solid cornstarch particles are 'swimming' in the vegetable oil and in the presence of an electric field - the region around a charged object (the balloon in this case), the viscosity or how runny the substance is changes. Near the balloon the substance becomes less runny and this is what makes it stop pouring - in sciency terms the slime is called a electrorheological liquid (people will think you are a super genius with that term!) 
These types of fluids are used in some brakes where a 'voltage' is applied to change the runny-ness of the fluid.  

But in greater detail we know that atoms contain electrons and so the negative charge of the balloon pushes the electrons in the 'cornstarch atoms' away and then we get a 'net' positive charge of the slime on the side closest to the balloon and so the slime moves towards the balloon due to what is called 'electrostatic' attraction,  as shown below:


Get making and spread some science!
