Reflection: Modeling Blood Vessels - The Roads of Life - Section 4: Elaborate


The use of models in my teaching has allowed me to bring abstract concepts to life for my students.  Life sciences are filled with processes and concepts that are difficult to observe and a result difficult to grasp your mind around.  This is even more true for my ELL students who lack the language to master content through more conventional means, such as writing and reading.  

Scientific Models can be any of the following:

 • An abstract, simplified representation of a system that makes its central features explicit and visible

• can be used to generate predictions and explanations for natural phenomena

• Mental (internal) and conceptual (expressed) models

In this particular lesson the use of modeling allowed my students to visually see how the diameter of a blood vessel can impact the blood flow.  It is one thing to say that eating foods with high cholesterol is bad for you because it causes heart attacks but it's another thing to actually see evidence of it before your own eyes.  The use of models allows for students to gain a deeper level of understanding on how our bodies intricate systems function to keep us alive.
