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.
