A.2.c. Scientific Modeling

Step 2. Scientific Modeling Research: Today we are learning about scientific models so we can improve our model and conceptual understanding of our phenomenon.

Scientific Models and Concept Maps convey information quickly and easily through visual representations. In this way they are similar to emojis and street signs.

Models show relationships and how things interact. They can be simple or complex.

The above examples represent ideas and convey information. What they don't do is explain how something works. In science we are always trying to understand and explain the cause and effect of phenomena. The problem in science is that we do not always know the cause nor can we see the them without the aid of advanced technology. For that reason, our knowledge is always changing. Our knowledge grows as we learn more. Thus, scientific models will change and grow with our knowledge. We call our first model the initial or beginning model. We call our middle models the working model, and our last model is called the final model. Yet a model is never truly finished. It can always improve.

There is a wide-range of what models can be. Generally models become more complex as our knowledge about the topic increases. Examples of models are replicas, diagrams, mathematical equations, and computer simulations. We think of our models as initial or beginning model, working model (of which there can be several), and final model.

Physical replicas can be 2-dimensional or 3-dimensional models that represent all the working parts.

Diagrams represent how things work or how processes flow. In the right, you see a diagram for how to set up a science experiment. Process models take the place of 100s of words for explaining set up and procedures. Yet you should always have a key (like on a map) or clearly labeled parts.

  1. Reread the close reading entitled "Why do we put salt on the roads?" and draw a scientific model or concept map that shows how salt interacts with water molecules to prevent freezing. This process is called Freezing Point Depression. Clarification: Draw a model of freezing point depression.
