Our Middle School students have been completing a food science unit, which has recently been looking at acids and bases. The students were asked to make a natural indicator at home. This can be done with many different foods, an indicator will turn a solution a different colour depending on the pH level. Students were asked to choose 3 different substances in their kitchen/ laundry that they could test. Some examples include bicarb soda, vinegar, dish-washing liquid, or even soda water.
You can view some of the results below, the colour chart shows what colour the solution will turn depending on the pH of the substance, and depending on what natural indicator the student used. Red cabbage was most popular, but in the last one curry powder was used. Our students will be doing more Science at home next week and at the start of next term, so stay tuned for more fun!
