Digestion is the process by which the food we eat is broken down into nutrients that can be used by the body. Carbohydrates are broken down into sugars, which can be used in respiration. Proteins are broken into amino acids, which can be used for growth and repair in our bodies. The digestive system has a number of different, well adapted parts that work together to take food from bite-size to useful molecules that your body can use. The following activities aim to introduce students to this process with fun visual aids.
