I know it is a little early, but we are very close to breaking up for our Christmas holiday. I received a very unnecessary but very much appreciated gift from a fabulous former student. It is certainly very festive. Many thanks and have a great Christmas.
With year 11, a quick recap on the factors affecting rates of reaction. These two demonstrations showed clearly that a higher concentration of hydrogen peroxide gives a faster reaction (elephant’s toothpaste).
Then we added zinc to a high concentration acid (orange balloon) and a low concentration of acid (red balloon) and waited for the hydrogen gas to form. Once again, high concentration filled up first.
Due to the numbers of staff who were absent today, the decision has been made to close the school to years 9 and 10 for Thursday and Friday this week. Work will therefore be posted here (as a summary) and on school’s Insight account and work can be accessed by remote access.
