Modeling in Science with Storyboard That

By Oliver Smith

Modeling allows us to make our own sense of what and why something is happening. Conceptual models are shared and explicit representations or analogies of phenomena and are used by scientists to help them understand the world around us. Models are used in all areas of science and offer external versions of mental concepts. Models are not a perfect representation; they are a simplified version of a system that highlights certain areas while ignoring others.

The Digestive System

Lesson Plans by Oliver Smith

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.

Storyboard Text

  • What would you like?
  • I'll go for a turkey sandwich with lettuce and tomato.
  • Amber is hungry, so she goes to a store to buy some food.
  • She decides to order a turkey sandwich.
  • Amber takes a bite. First the food is chewed which breaks it up into smaller pieces. The turkey sandwich is also mixed with saliva that contains enzymes.
  • The partially digested food, known as a bolus, then passes through a tube called the esophagus. A muscular wave-like motion called peristalsis moves the bolus down the tube.
  • The bolus reaches the end of the tube and lands in the stomach. The bolus is mixed gastric juices to make a thick liquid called chyme.
  • The bolus then passes through the stomach to the small intestines. There, the chyme is mixed with enzymes and bile to help further break down the food.
  • Enzymes are produced in the pancreas. Bile is produced in the liver and stored in the gall bladder.
  • As the food moves along the small intestines, some of the nutrients are absorbed into the blood.
  • The food then passes into the large intestines where water is reabsorbed. What is left is food that can't be digested known as feces. Feces leave the alimentary canal through the anus.
