The theme for this year’s British Science Week was ‘change’, with Year 7 and 8 students enjoying a series of scientific investigations related to changes happening in the world, from seasons and climates to materials and energy. They also considered changes that could have a positive impact on the future.
One task involved students looking at sand and what changes had been made to it to make it stick together. The students used kinetic sand and were introduced to ‘Nanotechnology’, which is the study and application of extremely small things and can be used across all science fields and engineering.
Some students took on the challenge of modelling a building of the future in preparation for potentially flooded areas by designing a platform that could support weight and also withstand water pressure. Other groups looked at the reversible reaction of heating chocolate and saw that this did not work for all reactions when they heated and then cooled egg white.
There was much excitement at building a ‘marble run’ that would last 15 seconds! For most this involved designing and then modifying their plans to try to slow down the marble on its path. The winning girls thought ‘outside the box’, with an innovative design for an unstable platform which undulated the marble back and forth rather than a traditional marble run.
Kelly Archer, Science Teacher, said, “The week was a great opportunity for students to immerse themselves in a scientific topic with a range of experiments to develop their skills and knowledge.”
