Ample use of liquid nitrogen and dry ice was a winning outreach strategy employed by CNBP Research Fellow, Alf Garcia-Bennett in his attempt to demonstrate to Year 1 school children, the differing states of matter.
In an hour long presentation to approximately 25 young students at Cammeray Public School in Sydney, Garcia-Bennett used these substances to demonstrate changes from liquids and solids to gas.
The changing properties of matter due to temperature was also demonstrated with the cooling of a piece of rubber to liquid nitrogen temperatures, where it was made brittle instead of flexible.
According to Garcia-Bennett, “The children had a lot of fun understanding the scale of matter from the size of a human hair to the size of atoms. They were also curious and surprisingly aware of concepts like particles and atoms. They particularly enjoyed the bubbles created by dry ice in contact with water and learnt how gases can be trapped within bubbles”.
Summing up the experience, Garcia-Bennett concluded, “It was a fun day with more outreach demonstrations to come in the future”.

CNBP Deputy Director, Prof Ewa Goldys had an inspiring visit to Sydney Girls High School on Thursday, June 11, 2015 where she acted as an ‘expert judge’ in assessing Year 9 students and their research projects as part of the school’s annual Science Conference.
Students designed and performed an investigation into a research area of their own choosing (a part of the NSW Science Curriculum) with the Conference providing a forum where students could present their research to an expert panel.
The panel not only provided students with feedback relating to their investigation, but also determined the projects worthy of further recognition. The determination considered both experimental design and the ability of the student to communicate their ideas.
Goldys enjoyed attending and judging the competition noting, “All students were enthusiastic and their work prepared to a very high standard. The winning entries were intellectually sophisticated and impressively presented. This is an excellent initiative and we are hoping to maintain our association with this activity over future years.”
Areas investigated by the students ranged from gel electrophoresis to clean energy.
