Junior Science

It has been a hands-on week in the Junior School Science Lab which is what the girls love best as they see science come to life before their eyes.

Year 1 girls were the first to don their safety spectacles, and, using laboratory equipment such as pestle and mortar, measuring cylinders, filters and funnels, they worked together to extract and blend perfumes from mint, lemons and roses.

Meanwhile, Year 2 were revising their knowledge of amphibians and the frog life cycle. The girls soon realised why each frog lays as many as 100 eggs. Frogspawn, tadpoles and froglets are all prey in the complex food webs of a pond habitat and only a very few will reach adulthood. The girls were justifiably proud of their beautiful 3D life cycle models created using coloured dough and paper plates.

Year 5 enjoyed a set of challenges from Professor Snape designed to be solved in their House teams. It was strictly a NWA lesson (No Wands Allowed) as our young wizards worked to create a Stupefying Lamp to mesmerize, an Acromantula and then disassembled Sleekeazy Hair Tonic potion into its individual components. Having to wait a whole week to see if they had recovered crystals of African sea salt by evaporation from the Sleekeazy Hair Tonic soon has Owls flying to and fro, carrying disgruntled messages, as students grumbled about the length of time sometimes needed to see results in Muggle science.

Finally, Year 6 visited the Chemistry Department in the Senior School. The girls’ special topic this term is World War I and they began by watching the effects of chlorine gas on a rose which made them reflect on its use in the trenches. In addition, they saw how chlorine gas was produced and how it can be combined with sodium, to create sodium chloride. Then, working in pairs, they used an electrical current to separate salt water into its chemical constituents and were able to smell chlorine being produced.
