Science Prayer We have the offspring of your love. So we write our praises to you. Make us the species that can function of all your significant system. And the energy that flows within the biosphere. Help us be the producer. Not only the consumers of your enduring love here on Earth. This we pray in the main source of life. Our breathe and soul, Jesus Christ. Amen. 1. describe and explain the different models used by the scientist to explain phenomena that cannot be easily seen or detected. 2. describe particle model of matter; and 3. recognize that matter consists of tiny particles.  WORD BANK Acid Metalloid Base Nonmetal Compound Pure Substance Colloid Mixture Elements Solution Heterogeneous Suspension Homogeneous Metal Salt ACTIVITY 1.2 DISCUSSION – GRAPHIC ACTIVITY 2.1 – GRAPHIC ORGANIZER ORGANIZER  Explain Matter is defined as anything that occupies space and has mass. Mass - A measure of how much matter is in an object. Weight - A measure of the force of gravity on an object. Volume - The amount of space that matter occupies. Calculating Weight  Question: What are the States of Matter Explain and the Phases of Matter? A physical condition of a matter In terms of temperature, refers to change in state Explain States of Matter Explain States of Matter  Guide questions: 1. What do we call these representations of the molecules of solid, liquid and gas? 2. What is the importance of using scientific representations like this in learning science? 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? Guide Questions: 1. What do you think a scientific model is? 2. Can you give an example of a scientific model you have encountered before? 3. Why do you think scientists use models to understand phenomena?  Scientists use models to study complex concepts and difficult to study directly. Models are useful tools to understand complex systems by allowing them to investigate and make predictions. Models are created on computers because of their enormous amount of data.  Models can be used to test ideas by simulating specific parts of a system. Models can also be used to make predictions about the future. Scientist used past data to assess the accuracy of a model. Models have limitations and can be improve.  There are different types of models: 1. physical models - smaller and simpler representations. 2.conceptual models - tie together many ideas to explain a phenomenon or event. 3.mathematical models - sets of equation that consider many factors to represent phenomenon. 4.simulation models - use a digital prototype of a physical model to predict its performance in the real world. PhET: Free online physics, chemistry, biology, earth science and math simulations (colorado.edu) 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 understand? 1. How do the characteristics of the Plum Pudding Model, the Bohr Model, and the Rutherford Model help us understand the behavior of particles within atoms? 2. What similarities and differences do you notice between the arrangement of particles within atoms and the behavior of particles in different states of matter?  – All matter is made up of tiny particles called atoms or molecules. Atoms are the fundamental building blocks of elements, while molecules consist of two or more atoms chemically bonded together. Particles are constantly in motion: in solids, particles vibrate in place. in liquids and gases, particles move from one location to another.  – In solids, particles are closely packed with minimal space between them. In liquids and gases, particles have more space between them. As temperature increases, particle motion speeds up. o Higher kinetic energy leads to faster vibrations and movement of particles. 1. Explain how scientists use models to represent the unseen world. 2. How does the particle model explain the difference between solids, liquids, and gases? Any questions? Clarifications?
