 PRAYER Our Father, Who art in heaven, Hallowed be Thy Name. Thy Kingdom come, Thy Will be done, On earth as it is in Heaven. Give us this day, our daily bread, And forgive us our trespasses, as we forgive those who trespass against us. And lead us not into temptation, but deliver us from evil.Amen  I am My name is Rich Cyrene O. Diaz and I will be your Science Teacher for the school year 2024-2025 Make sure to be here before 6:45 AM because we have a flag ceremony every day. The grading criteria for students will be as follows: 40% 30% 30% Written Performance Quarterly Works Tasks Exam  Be Respectful Be on Time Be Honest Be Prepared Be Prompt Be Responsible Be Participative Use of models Quarter 1: Module 1  LESSON OBJECTIVES Define what a scientific model is and explain its purpose in scientific research; create simple physical or conceptual models to represent a given phenomenon; reflect on the limitations of models, recognizing that models are simplifications and may not capture every aspect of the phenomena they represent. The Role of Models in Science Scientists use models to help them understand and explain things that are too small, too big, or too complex to see directly. A model is like a mini version of something that shows how it works. Types of Models: Physical Models: These are small versions of bigger things. For example, a globe is a model of Earth. Mathematical Models: These use numbers and equations to show how things work. For example, formulas that predict how fast a car will go. Types of Models: Conceptual Models: These are drawings or diagrams that explain ideas. For example, the water cycle diagram shows how water moves around the Earth. Computer Models/Simulations: These use computers to show what might happen in the future. For example, weather forecast models predict rain or sunshine. Why Models are Important: Visualization: Models help us see things we can't normally see, like atoms or distant planets. Simplification: They make complicated things easier to understand by focusing on the main parts.  Why Models are Important: Prediction: Models can help us guess what Communication: might happen in the future, like Models help scientists predicting the weather. explain their ideas to others. Testing Ideas: Scientists can use models to test their ideas and see what happens when they change something. Examples in Different Fields: Astronomy: Models of the solar system help us understand the planets' movements. Biology: Genetic models show how traits are passed from parents to children. Physics: Models of forces explain how objects move and interact. Environmental Science: Climate models show how the Earth’s climate might change over time. Use of Models in the Science of Materials The science of materials is about studying different materials to make them better or create new ones. Models help scientists see and understand materials at the tiniest levels, like atoms and molecules. Properties of Liquids High Density Liquids have a relatively high density compared to gases, meaning they are more massive per unit of volume. Flowability Liquids are able to flow and be poured due to the mobility of their particles, which can slide and move past each other.  Particles of Liquids Closely Packed The particles of liquids are closely packed, but not Kinetic Energy arranged in a regular pattern The particles have more kinetic like in solids. energy than solid particles, allowing them to move and Attraction slide past each other while remaining relatively close The attractive forces between together. liquid particles are weaker than in solids, but stronger than in gases. Atomic and Molecular Models: Crystal Structures: These models show how atoms are arranged in solids. For example, a model of salt crystals shows the pattern of sodium and chloride atoms. Molecular Dynamics: These models show how atoms and molecules move and interact over time, helping predict how strong or flexible a material will be. Designing New Materials: Nanomaterials: Models help create very tiny materials used in electronics and medicine. Composite Materials: By combining different materials, scientists can make stronger or lighter materials. Predictive Modeling: Phase Diagrams: These models show what happens to a material when you change the temperature or pressure. For example, they help make stronger steel. Stress and Strain Models: These models predict how materials will behave when forces are applied to them, like how much weight a bridge can hold. Applications in Industry: Semiconductors: Models help make better computer chips. Polymers: Models help create new kinds of plastics.  Advancements through Modeling: 3D Printing: This uses models to build objects layer by layer. Materials Discovery: Models help find new materials faster by predicting their properties before they are made.  CONCLUSIONS Models are very important in science. They help us understand things that we can't see directly, like tiny atoms or huge planets. In the science of materials, models help us create new materials and improve existing ones. By using models, scientists can test their ideas, make predictions, and explain their findings to others.  What is a scientific model?

They will choose from one of the following topics: The Water Cycle The Structure of an Atom The Solar System Plant Cell Structure  Materials Needed Chart paper Markers, crayons, and colored pencils Clay or playdough Craft supplies (e.g., sticks, balls, glue, scissors, string) Cardboard and other recyclable materials Reference materials (textbooks, internet access, printouts)  Instructions Group Formation (5 minutes): Divide the class into small groups (3-4 students per group) Planning (10 minutes): Each group chooses one phenomenon to model. Groups discuss and plan how they will create their model and what materials they will use. Groups should decide whether their model will be physical (3D) or conceptual (2D, diagram).  Instructions Model Creation (30 minutes): Groups create their models using the provided materials.Encourage creativity and teamwork. Presentation and Explanation (20 minutes): Each group presents their model to the class. Groups explain what their model represents and how it helps to understand the phenomenon.  Example Models Water Cycle: A 3D diorama showing evaporation, condensation, precipitation, and collection using clay, cotton, and blue cellophane. Structure of an Atom: A 3D model using styrofoam balls for protons, neutrons, and electrons with toothpicks or wires to show electron orbits. Solar System: A 3D hanging mobile using different sized balls painted as planets, hung from a cardboard or foam board sun. Plant Cell Structure: A 2D diagram on chart paper showing labeled parts like the cell wall, nucleus, chloroplasts, and vacuole, or a 3D model using clay and craft supplies.   For more games, visit Hivessel.com Don't forget to support us in our socials below!
