THREE STATES OF MATTER IN SCIENCE 8.pptx
- 2. Solid Liquid Gas Guide question: 1.What do we call these representations of the solid, liquid, and gas? 2.What is the importance of using scientific representations like this in learning science?
- 3. Scientific Models Essential Questions: 1.How can we visualize things that cannot be seen by the eye? 2.How can we visualize things that is too big, and complex be examined in actuality?
- 4. Scientific Models A scientific model is a representation of real- world phenomena. Scientists, educators, and learners all use scientific models to understand the phenomenon in question better. Using models can also help scientists make predictions based on data collected about a particular phenomenon for how it may behave.
- 6. Activity: Scavenger Hunt Procedure: o Gather the students and explain that they will be embarking on a comprehensive vocabulary scavenger hunt to discover important terms related to scientific models and the particle model of matter. o Briefly review the purpose of the activity and emphasize that it's an opportunity to learn and have fun while reinforcing their understanding of key concepts. o Divide the class into small groups or pairs. Students will get random cards passed backwards from the teacher. o Provide each group with a list of all the vocabulary words they need to find. o Set a timer and let the groups begin their scavenger hunt to locate the hidden vocabulary cards. o Encourage students to read and discuss the meaning of each word once they find it. They can also brainstorm examples or real-life applications of the vocabulary words
- 7. What do you think is “Scientific Model” is? In science, a model is a 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.
- 9. Different types of Scientific Model Physical models Conceptual models Mathematical models
- 10. Physical Models Physical models are smaller and simpler representations of a thing being studied.
- 15. Conceptual Model tie together many ideas to explain a phenomenon or event. Examples: atom model, molecular
- 18. Mathematic al Model -are sets of equations that consider many factors to represent a phenomenon. Mathematical models are usually done on
- 20. • Simulation models use a digital prototype of a physical model to predict its performance in the real world. • Many models are created on computers because they can handle enormous amounts of data. • Models can be used to test ideas by simulating specific parts of a system, making it easier for scientists to understand how certain factors affect each other. • Models can also be used to make predictions about the future, with the best ones considering multiple factors. • To assess the accuracy of a model, scientists often use past data to see if the model can accurately predict the present. • Despite their usefulness, models have limitations because they are simpler than real systems and may not predict real-world behavior with absolute accuracy. However, careful construction and sufficient computing power can improve a model’s accuracy.
- 21. Can you give an example of a scientific model you have encountered before?
- 22. Why do you think scientists use models to understand phenomena?
- 23. Scientists use models because reality, especially systems like Earth’s climate, is complex and difficult to study directly. o Many factors influence complex concepts, for example climate, so it’s impossible to consider all of them simultaneously, that is why models are necessary. o Models are useful tools that help scientists understand complex systems by allowing them to analyze and make predictions. o There are different types of models: physical models, conceptual models, and mathematical models. o Physical models are smaller and simpler representations of a thing being studied. A globe or a map is a physical model of a portion or all of Earth. o Conceptual models tie together many ideas to explain a phenomenon or event
- 26. 1. Analyze the given model of the atom. Just by looking at it, in your own words, describe what an atom is. 2. How did the model help you understand how people see atom back in the days of Democritus? Is it helpful and easy to
