Over the past week, each of the classes in Years 5 and 6 have been visiting the L'Oreal Young Scientists Institute at the Royal Institution. They had been using their knowledge of changing states to create their own lip balms and bath bombs!
We started by making sure we all looked like real scientists, so we popped on our white coats and safety gloves. After, we learnt all about the PH scale and tested different liquids for their acidity levels. It turns out that lime juice has a very high acidity level!
Before long, we needed to get working on our bath bombs, using all of the knowledge we had about acids and alkalies. We started by measuring out our citric acid and sodium bicarbonate, before adding a few sprays of witch hazel, and of course our colored dyes and scents. We had so many scents to choose from, from mint chocolate chip to coconut!
After lunch, whilst our bath bombs were baking, we learnt about how to make lip balm. We started by melting bees wax, from solid pellets into a liquid, this was then mixed together with either avocado or almond oil. Once our solution was got, we then had the opportunity to add our scent and colors. Vanilla was very popular!
We had a fantastic day at the Royal Institution, and have very much enjoyed testing out our lip balms and bath bombs at home!
