Over the duration of 3 weeks, groups of Year 6 students from Warwick Prep came to the Science department at King's to give them an insight of what its like to study science at secondary school. Many of them will be joining King's in September, so it was nice for them to get familiar with their surroundings. During their visit, we went over the pH scale and examples of substances with different pH's that they would know, from car batteries to toothpaste. Afterwards we did a lab demonstration where we tested the pH's of 6 different colourless solutions with Universal Indicator and matched them up with correct pH value via the pH scale. We also spoke a little about lab safety, you'll see the safety goggles in the pictures. Additionally, the science technicians helped us make a rainbow in a burette, which was extremely exciting! We did this by placing a small volume of strong acid in the burette with some Universal Indicator, which went red, then via a funnel, adding some strong base. The 2 solutions reacted and produced a vertical rainbow, shown due to the Universal Indicator present. We got some great photos of their visit...
