WEEK 7 - SCIENCE ROTATIONS

This week the Year 5 classes started their science rotations. Here are some amazing photos of Room 17 doing an experiment with Mrs Riddell in Room 15.

HOW CAN RED CABBAGE BE USED AS AN INDICATOR?

 Red cabbage contains a chemical called anthocyanin that changes colour depending on the acidity of its environment. This means it is a pH indicator, a gauge that tells you how acidic or basic the surrounding environment is.

The experiment the students did uses red cabbage as the pH indicator and put with different liquids, they could see which liquids are acidic and which liquids are basic.

Although it didn't seem like much to us, it was food fit for a king. I have been called out to the front lines and over sixty of my fellow comrades have already died in less than two minutes and three seconds. I personally don't think I will ...
