USE OF MODELS PREPARED BY: MERRYL JOY L. VIEJO OBJECTIVES Define Model Differentiate the different types of models Explain the use of models Scientific Model representation of an idea, an object or even a process or a system that is used to describe and explain phenomena that cannot be experienced directly visual way of linking theory with experiment, and they guide research by being simplified representations of an imagined reality that enable predictions to be developed and tested by experiment Scientific Model representation of objects, systems or events and are used as tools for understanding the natural world with the use familiar objects to represent unfamiliar things. helps visualize, or picture in the mind, something that is difficult to see or understand  WHAT MODELS CAN REPRESENT? Models can represent Example Objects that are too small to see Model of an atom or a cell Objects that are too big to see Model of the planets Objects that no longer exist Model of a dinosaur Objects that have not yet been Prototype models such as a model invented of a robot Events that occur too slowly to Model of mountain formation see Events that occur too fast to see Model to predict an earthquake Events that have yet to happen Model of weather system DIFFERENT TYPES OF MODELS  CONCEPTUAL MODEL Qualitative models or representations that provide a broad overview or analogy to explain a phenomenon, system or problem Models that help to understand abstract concepts Example : Atom Model, Molecular Model  PHYSICAL MODELS Are tangible representations of real objects, situations, or phenomena smaller and simpler representations of the thing being studied often three-dimensional. Example : Human Skeleton, Globe, Map  MATHEMATICAL MODELS Models that use mathematical language or formulas to represent relationships between variables or describe a system’s behavior in terms of symbols, equations, and numbers. Example: Model of Newton’s second law of Motion, Trajectory of spacecraft  F = ma NEWTON’S SECOND LAW OF MOTION  USES OF MODELS SIMPLICATION PREDICTION CONTROL Complex systems can Models enable Models can help in be overwhelming. scientists and designing safe Models compress researchers to make systems. information by educated forecasts focusing on the most about future events vital aspects INTERPRETATION VISUALIZATION Models assist in data Models render abstract interpretation, providing concepts tangible. insights into important mechanisms that are not easy to identify.  LIMITATIONS OF MODELS MISSING DETAILS LACK OF ACCURACY Models are like detailed pictures The models simplify things too much, drawn with only a few crayons. making them less accurate. Models is Models need data to work, but if the simple and easy to draw data is incomplete, outdated, or biased, APPROXIMATIONS Models do not exactly contain or show all the details of the concepts they represent and may not be able to take into account all necessary data, such as in the case of predicting events. Do not behave exactly like the things they represent THE ROLE OF MODELS IN BREAKTHROUGH DISCOVERIES  THE PARTICLE MODEL OF THE ATOM ATOM were once considered the smallest units that Consists of sub-atomic particles, such as PROTONS, NEUTRONS AND ELECTRONS.  THE BOHR MODEL OF THE ATOM - Devised by Danish scientist, NIELS BOHR in 1915. - He modified the atomic structure model by explaining that electrons move in fixed orbitals (shells) and not anywhere in between and he also explained that each orbit (shell) has a fixed energy.  REMINDERS Scientific models are representations of systems that help explain and visualize scientific processes and natural phenomena. Models can take different forms, such as conceptual, physical and mathematical Scientific models have limitations and may not capture all the details or accurately represent reality. Models can change over time due to new discoveries and the need for updated or revised information. THANK YOU! QUIZ TIME! 1.Which of the following statements on models is correct? a. The data is always accurate. b. The information cannot be changed or updated c. Scientists are used to simplifying complex phenomena d. Complex equations can be used to describe real – world situations 2. Why do models have limitations? a. Because they make models too complicated b. Because they always match reality perfectly c. Because they cannot aid in making predictions d. Because they may oversimplify reality, leading to inaccuracies 3. How can outdated or biased data affect a model? a. They improve the model’s accuracy b. They make model more relatable c. They have no impact on the model’s calculations d. They can lead to incorrect or misleading representations 4. Which of the following is NOT an example of a scientific model? a. Physical Model b. Conceptual Model c. Fashion Model d. Mathematical Model 5. Which of the following is NOT a limitation of Model? a. Visualization b. Missing Details c. Lack Of Accuracy d. Approximations  COMPLETE THE TABLE In the table below, fill out the required details to complete the table Who is the What is the Draw the Danish name of his Model of the scientist? model of atom? atom
