The Workshop

(Scroll down for posters and more!)

Over 100 years ago in Holland, a scientist (Heike Kamerlingh Onnes) designed a way to turn helium gas into a liquid - and the temperature of the liquid dropped to -269 degrees C i.e. very, very, very cold: a Cryogenic temperature. He then designed more experiments to find out what happened when he put things in this liquid and made them very, very, very cold too. In 1911 one of these things was mercury and what happened was magical: it could conduct electricity without any resistance! It was a Superconductor.

Modern superconductors can be cooled with liquid nitrogen (at -196 degrees C) as can lots of other things, including sausages, bananas, flowers, tennis balls, metal plates and more. Using such items and lots of liquid nitrogen, various aspects of science and engineering, from material properties to engineering design, as well as the uses of cryogenics, are explained and explored with the students via exciting demonstrations and creative activities. The topics of electricity, electrical power generation and transmission now and in the future and superconductivity are also covered and the workshop topped off with the ever-popular levitating magnet demonstration.

The workshop is preceeded with a look at some amazing female scientists & engineers throughout history (Women in STEM Heroes) and may be supplemented by the Future Grid Challenge.

Feedback

Dragonfly Day 2015



‘I really enjoyed the workshop with liquid nitrogen.’
‘I liked being able to watch and join in experiments, mainly in frozen aliens and super powers.’

‘I enjoyed learning about jobs I never knew even existed.’

‘I enjoyed knowing what other women are doing and how they got interested in it.’

‘My favourite part was watching experiments with liquid nitrogen.’

‘I enjoyed all of it because it gives girls the opportunity to see what STEM is like and I also learned that engineering is for any gender.’

‘Liquid nitrogen is really cool….like really cool.’

Highfield School Fayre 2015



'You were ammmmmazing so thank you so much for being with us on Saturday. The kids absolutely loved having you with us and hope you enjoyed being with us too.'

Alton College Engineering Summer School - Careers Talk 2015

'The students loved the talked and have been talking non stop about it all morning!'

UTC Visit Day 2015

'Thanks very much for delivering your session for visit today – apologies I wasn’t able to stop and chat much or help you clear up! Feedback from the session was as always very positive – afraid the feedback forms weren’t filled out that thoroughly but most of the comments were along the lines of ‘great / cool / amazing’ and chatting to the students and teachers on the tours they were really excited about what they saw today. The balance of demonstration & information was spot on, and you kept their attention for the whole hour which I think was a bonus with this group!'

Shirley Primary Workshops 2014

'Thank you so much for your enthusiasm and energy yesterday, the children loved it.'
'As year 4 loved it so much when you came and visited last week, they wondered if you could come back next year! They would love it if you could talk to next years year 4s in September to link in with a solids, liquids and gases topic.'

National Women in Engineering Day 2014

Cowes Enterprise College visit to the University of Southampton including lab tours and two workshop sessions - Student report

'On the 23rd June 2014, a small group of girls from Cowes Enterprise College travelled to Southampton University for a day all about women in the engineering industry. The day featured lectures, demonstrations and a tour of Southampton University itself. The lectures and demonstrations all showed us elements of the different jobs that the engineering industry has. We saw some great demonstrations throughout the day. Included was a demonstration of glass blowing. During this we watched someone heat up a glass tube with some gas. When the person had heated it up, they blew into it and produced a bubble. Not like any other bubble however it became a solid glass circular end to the tube which did not break when touched! We also saw an amazing example of cryogenics. Cryogenics consists of the study of materials taken to extremely low temperatures. A peeled banana was frozen in some liquid nitrogen, and then used it as a hammer to hammer a nail into some wood! It truly was something you would not see every day! As well as all the demonstrations I really liked the tour of Southampton University. It was a giant campus area. It even had roads with proper crossing and a 5 floor library! This experience definitely made me look quite differently at the engineering industry. It was worthwhile and I as well as many others enjoyed it quite a lot. It has inspired me to want to take a degree course in the future. '
