Modellering i Science med Storyboard That

Af Oliver Smith

Modellering giver os mulighed for at gøre vores egen mening om, hvad og hvorfor noget sker. Konceptuelle modeller er delte og eksplicitte repræsentationer eller analogier af fænomener og bruges af forskere til at hjælpe dem med at forstå verden omkring os. Modeller bruges inden for alle videnskabelige områder og tilbyder eksterne versioner af mentale koncepter. Modeller er ikke en perfekt repræsentation; de er en forenklet version af et system, der fremhæver bestemte områder, mens man ignorerer andre.

How is food digested? Use digital storytelling in science with comics!

Storyboard Tekst

  • 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.
