Nightschool: epidemics & ecosystems
One of the main objectives of science education has been to improve students’ scientific habits of mind, grow their capacity to participate in scientific inquiry, and teach them how to reason in a scientific sense since its inception [1, 2]. However, there has always been a conflict between the focus that should be placed on improving knowledge of scientific material and the emphasis that should be placed on scientific activities. Students are left with simplistic conceptions of the essence of scientific inquiry  and the belief that science is merely a series of isolated facts  as a result of a limited emphasis on content alone.
This chapter emphasizes the importance of increasing students’ understanding of how science and engineering accomplish their goals while also improving their competency in related activities. As previously stated, we use the word “practices” rather than “skills” to emphasize that scientific inquiry necessitates simultaneous coordination of both experience and expertise.
Can one mathematical model explain all patterns in nature
Student and science perspectives are at odds.

Everyday encounters of students
Computer simulation: exploring nature with a computer
Models are often mistaken by younger students as either toys or plain replicas of reality. This is roughly in line with the everyday sense of the word “model” (for example, “model cars,” “model airplanes,” and “model railroads”). Models are also considered to be useful by students since they are replicas (or even size reproductions) of real objects or actions. In such instances, students seldom look past the model’s surface similarities to the object or concept it represents (that is, the value of a model of X would be decided by the question, “Does it look like X?”). The scientific sense of the word “model” varies from how it is used in daily life, as it does in many other fields of science. This is crucial in learning how students interact with models on a daily basis. See the emphasis idea for more detail about how to incorporate scientific terminology.
Ideas for critical instruction
Scientists construct models and use them to make predictions, which students can understand. Since models are representations of scientific understandings, they shift as these understandings change. The key concept

Systems and Models of Systems
Intro to history of science: crash course history of science #1
Models can be used to understand and predict the behavior of systems. A system is an ordered set of similar artifacts or components; models can be used to understand and predict the behavior of systems.

NGSS Appendix G – Crosscutting Concepts K-12 Progressions
Students recognize that a system is a set of interconnected parts that work together to form a whole and can perform tasks that individual parts cannot. They can also be used to define a system in terms of its components and how they communicate.
Students should recognize that systems can communicate with one another, that they can have subsystems, and that they can be a part of larger, more complex systems. Models may be used to describe systems and their interactions, including inputs, processes, and outputs, as well as energy, matter, and information flows within systems. They will also learn that models are constrained in that they can only represent a portion of the structure under investigation.
By specifying a system’s boundaries and initial conditions, as well as its inputs and outputs, students may investigate or evaluate it. They can simulate the flow of energy, matter, and interactions within and between systems at various scales using models (e.g., physical, mathematical, and computer models). They may also use models and simulations to predict a system’s behaviour, but they must be aware that due to the assumptions and approximations in the models, these predictions have limited precision and reliability. They can also create structures that perform particular functions.
Nature of science
Scientific modeling is a form of research that aims to make a specific part or function of the world easier to comprehend, describe, measure, imagine, or simulate by referencing it to established and generally accepted information. It entails choosing and defining relevant aspects of a situation in the real world, as well as using various types of models for various purposes, such as conceptual models to better understand the situation, operational models to operationalize it, mathematical models to measure it, and graphical models to visualize it.
…the sciences don’t try to describe things, and they don’t even try to analyze them; instead, they just render models. A model is a mathematical construct that explains observable phenomena with the addition of some verbal interpretations. The sole and precise justification for such a mathematical concept is that it is supposed to work—that is, to correctly explain phenomena over a relatively large region.
Scientific modeling is also getting more attention in fields like science education, philosophy of science, systems theory, and information visualization. There is a growing body of information about all forms of advanced scientific modeling, including processes, techniques, and meta-theory.
