Today was Chemistry Day for the lucky 33 students who were part of the Nexus Year 5 Easter Camp. They started their day with some wake-and-shake activities lead by Mr Chapman which seem to involve lots of throwing paper around and raucous laughter.
The first activity gave the children the chance to get hands on with some chemicals. They were provided with a variety of household chemicals, from orange juice to hand soap, to test whether they were acidic or alkaline. The children were introduced to the idea of the pH scale and shown how to measure pH using universal indicator paper. They were then challenged to produce a ‘Rainbow’ column using a mixture of acid, alkali and universal indicator solution.
The second workshop saw the children back in the lab for another hands on practical activity. They were challenged to create their own acid-alkali indicator solution using red cabbage. The results were impressive!
The final session of the day was a Harry Potter themed murder mystery, where the children had to test various different samples of poisons found on the shoes of three suspects. They then compared the results of their ‘flame tests’ to some known samples to identify the person who had poisoned Dumbledore.
