Creating a Scientific Model
Why do we use models?
• Simplify complex processes• Accurately represent a structures• Memory tool to help us learn• Make predictions or to develop scenarios
Types of Models
• Actual physical representation also called replicas.
Types of Models- Continued
• Labeled drawings/ sketches• Mathmatical or chemical equations
Types of Models-Continued
• Computer Prediction Models- allows us to predict outcomes on a large complex scale
• We use these when we can’t perform a traditional experiment.
How do we create a Model?
• Step 1: Identify the phenomenon/ What do you want to explain?
• Step 2: Work to refine steps/Select type of Model
• Step 3: Apply the theoretical/ What does the model tell us?
• Step 4: Apply the model.
Now try it yourself
• The Phenomenon will be digestion.
• Gross, I know but it is something you all know a little about.
• In this case we are going to create a Model of pictures with labels.
First bite
• How will you represent steps in your model?
• Will you sketch a person or will you use shapes?
Let’s create a Model
• First bite to excretion
(keep it G-rated please!)
• To help you there is an short paragraph about digestion and also a diagram.
• Create your model directly into your notes.
• Colored Pencils are available to make it colorful if you like.
• YOU HAVE 10 Minutes!
Some Examples
Can your model be used in other cases?
Reading a Model
Write out what is happening in the Swimmer’s itch cycle step by step.
Reading a Model
• What organisms must be present to complete the life cycle of the Cercariae organism?
• What type of organisms are “molluscan”?
• Why do you think the creator made two different colored arrows?
