Modellierung in der Wissenschaft mit Storyboard That

Von Oliver Smith

Durch das Modellieren können wir nachvollziehen, was und warum etwas passiert. Konzeptmodelle sind gemeinsame und explizite Darstellungen oder Analogien von Phänomenen und werden von Wissenschaftlern verwendet, um ihnen zu helfen, die Welt um uns herum zu verstehen. Modelle werden in allen Bereichen der Wissenschaft eingesetzt und bieten externe Versionen von mentalen Konzepten. Modelle sind keine perfekte Darstellung; Sie sind eine vereinfachte Version eines Systems, das bestimmte Bereiche hervorhebt und andere ignoriert.

Storyboard Beschreibung

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

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.
