5th Class Science Experiment

This week we were learning about different types of food and the food pyramid. We used a chemical called Iodine and put drops of it on different pieces of food. We discovered that foods containing starch reacted with the iodine and turned a deep purple colour. We took photos of our investigation and recorded our results.
