On Wednesday, we went to the Salter’s Festival of Chemistry, which took place at The University of Oxford. When we got there, we took part in two different challenges. The first challenge was The Salters’ Challenge where we had to solve a mystery doing two different experiments, figuring out who stole the missing element on the periodic table. To do this, we did chromatography and various different test tube challenges. We worked in pairs to figure these out and compared answers with each other. Both parts of the challenge were very enjoyable!
After lunch, we took part in The University Challenge. For this we had to dissolve magnesium using sulphuric acid, as close as we could to 2 minutes 30 seconds. We had to change the concentration of the acid until the time was as close as possible. We managed to do this in 2 minutes 36 seconds. We were all very pleased with this result.
At the end, we enjoyed watching lots of experiments in a Chemistry demonstration in one of the university lecture theatres. Our favourite was the last one when we watched lots of different explosions of hydrogen and helium. We had to put our fingers in our ears and open our mouths the bangs were so loud! We all had a really fun day with lots of science.
