You’ve probably heard of a starch before when talking about food, but what is it and how do we identify it in foods? In the Starch Detector experiment, you won’t be eating starchy food, but detecting the amount of starch in potatoes and lemons! You’ll follow the step-by-step instructions from the lesson in the Online Classroom to set up your experiment, and watch what happens after you pour boiling water over these two foods and then add a mixture of copper(II) sulfate and potassium iodide. You’ll compare and contrast the results of these chemical reactions and learn of how photosynthesis contributes to the production of starches.
