Rates recap

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).

Higher concentration of hydrogen peroxide = faster reaction

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.

UK schools to close.

The process of setting up support for students to work from home has been accelerated when it was announced today that schools will close to the vast majority of pupils on Friday. It was also announced that summer GCSE and A-Level exams will be cancelled.

Partial School Closure

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.
