Study Notes
Scientific Models
- Scientific investigation involves observing and recording phenomena, either in a lab or in the field.
- A scientific model is an artificial representation of an object, natural phenomenon, or system, based on observations and existing knowledge.
- Models are used by scientists across various disciplines, from astronomy to biology and physics.
- Not all representations are scientific models; for example, a toy car is a scaled-down model, but not a scientific model.
Purpose of Scientific Models
- Models are useful for studying complex phenomena, especially when they are extremely small or large.
- Models can be used to explain how objects, organisms, or systems behave, even if the mechanisms are not directly observable.
- Models can help visualize processes and make predictions about how these processes might change over time or under new conditions.
- Effective models must incorporate all known components, their relationships, and account for all observations.
Types of Scientific Models
Two-Dimensional Models
- Two-dimensional models (2-D) include drawings, diagrams, and illustrations, used in classrooms, textbooks, journals, and research presentations.
- Examples include diagrams of the water cycle, and anatomical drawings of organisms.
Three-Dimensional Models
- Three-dimensional models (3D) provide more detail than 2-D models.
- Often used to study physical objects or living organisms.
- Subcategory: Structural Models: Represent physical objects (atoms, molecules, organisms, organs) used for studying components. Examples include models of the stomach, teeth, and viruses.
- Subcategory: Model Organisms: When direct study is not possible, organisms with comparable characteristics are used. Examples include fruit flies and birds as models for human diseases and to understand non-human species such as dinosaurs.
Mathematical Models
- Mathematical models use equations, graphs, formulas, and geometric illustrations to study relationships in data and make predictions.
- Examples include population graphs projecting future trends based on immigration levels and analysis of ecosystems over time.
- Can be created using complex computer programming. Examples include calculations about the universe's evolution.
