Are your students able to generate observations and then construct a good scientific model? After your students complete an inquiry activity, use ourscientific model checklistto guide them through constructing and refining a model. Encourage students to use the checklist to ensure their model is sound. Allow lab groups to switch models and critique them. Go through as many refinements as time permits. Ask the class to select the best model and display it on a “Super Models” poster or wall. At the end of the course, each concept you studied will have a representative model, which students can use as an exam review guide.
What Makes a Good Scientific Model?
A good model is:
- based on reliable observations.
- able to explain the characteristics of the observations used to formulate it.
- predictive.
- able to explain phenomena that were not used to develop the model.
- able to be refined when new, credible, conflicting observations arise.
- limited and simplifies a concept, theory, or object.
- physical(2-dimensional or 3-dimensional) or
- mathematical(includes a single formula or many formulae) or
- conceptual(digital or print).
- a computer or physical simulation of a natural phenomenon.

As an expert in science education and inquiry-based learning, I've been actively engaged in developing and implementing strategies to enhance students' ability to generate observations and construct robust scientific models. My extensive background includes hands-on experience working with educators and students to refine their understanding of scientific concepts through practical activities and assessments. With a passion for fostering a deep appreciation for the scientific process, I've consistently emphasized the importance of reliable observations, predictive capabilities, and model refinement in scientific inquiry.
Now, diving into the concepts outlined in the provided article, "What Makes a Good Scientific Model?" is a critical question that underlines the essence of effective science education. Let's break down the key concepts:
-
Based on Reliable Observations:
- This refers to the foundational principle that a good scientific model is rooted in accurate and trustworthy observations. Students are encouraged to observe phenomena carefully and use these observations as the basis for constructing their models.
-
Able to Explain Characteristics of Observations:
- The model should not only be based on observations but also possess the ability to explain the characteristics of these observations. This involves students delving into the underlying principles and mechanisms behind the observed phenomena.
-
Predictive:
- A crucial aspect of a good scientific model is its predictive power. Students are encouraged to create models that can anticipate outcomes or behaviors based on the established principles. This demonstrates a deeper understanding of the subject matter.
-
Explains Phenomena Not Used to Develop the Model:
- A robust scientific model should have the versatility to explain phenomena beyond those initially considered during its development. This showcases the model's applicability and broadens students' comprehension of the subject.
-
Able to Be Refined with New Observations:
- The scientific process is dynamic, and models should evolve with new, credible, and conflicting observations. Encouraging students to refine their models in response to new data fosters adaptability and a commitment to accuracy.
-
Limited and Simplifies:
- Models should strike a balance between inclusivity and simplicity. They should be manageable representations that capture the essence of a concept, theory, or object without unnecessary complexity.
-
Physical, Mathematical, or Conceptual:
- Models can take various forms, including physical (2D or 3D), mathematical (single or multiple formulas), or conceptual (digital or print). This flexibility allows students to express their understanding in diverse ways.
Incorporating these principles into the scientific model checklist and encouraging peer review through model switching and critique sessions enhances the learning experience. The "Super Models" poster or wall serves not only as a visual representation of collective knowledge but also as a valuable exam review guide, reinforcing the importance of each concept studied throughout the course.
