This lesson would be used during our nutrition unit when discussing carbohydrates. In this classroom activity young scholars investigate which foods have starch in them by using iodine, as well as investigate the result of iodine and lemon juice on paper by doing some "Magic Writing." Students will do a "Magic Writing" activity where they write a message on a piece of paper and predict what will happen when the paper is submerged into a water/iodine solution. Based on what the young scholars observed/learned in the "Magic Writing" activity, students will predict what will happen if iodine comes into contact with a starch found in certain foods. Young scholars will then use an eyedropper to put iodine on several food samples and record their observations. They will list food from the different food groups that tested positive for starch.
