Year 9 Science

by Lara Collard, 9E

During science for the last couple of weeks we have been focusing on chemistry and doing different experiments involving many different chemicals. The first experiment used Acids & Bases, which taught us how to differentiate between acids and bases using litmus paper, then using a universal indicator to find the overall acidity. In the next lesson, we did a round robin of experiments but the show stopper of them all was the Elephants Toothpaste, which is sodium iodide reacting with the hydrogen peroxide by removing oxygen atoms. Overall, I feel myself and the class has been really enjoying science this term and especially the last few weeks.
