Lesson Plan for 3rd Grade - Science - Energy (sources and types)

### Lesson Plan: Energy (Sources and Types) #### Grade: 3rd #### Subject: Science #### Duration: 60 minutes --- ### Objectives: - Students will understand what energy is. - Students will be able to identify different sources of energy. - Students will differentiate between renewable and non-renewable sources of energy. - Students will learn about different types of energy (e.g., kinetic, potential, thermal, etc.). ### Materials Needed: - Whiteboard and markers - Chart paper and markers - Flashcards with pictures/images of energy sources - Handouts with basic information on types of energy - Small objects for demonstration (battery-operated toy, rubber band, etc.) - Computer and projector (optional for video/presentation) - Worksheets for student activities ### Introduction (10 minutes) 1. **Warm-Up Question:** Ask students, “What do you think energy is?” Allow a few students to share their thoughts. 2. **Definition:** Explain that energy is the ability to do work or cause change. Write the definition on the whiteboard. 3. **Daily Examples:** Discuss common examples of energy in everyday life (e.g., light from a bulb, food giving us energy to move, a car using gasoline) ### Direct Instruction (15 minutes) 1. **Sources of Energy:** Explain the two main categories of energy sources: - **Renewable Sources** (e.g., solar, wind, water, geothermal, biomass) - **Non-Renewable Sources** (e.g., coal, oil, natural gas, nuclear) 2. **Types of Energy:** Go over different types of energy: - **Kinetic Energy:** Energy of motion (e.g., moving car, flying airplane) - **Potential Energy:** Stored energy (e.g., stretched rubber band, water held behind a dam) - **Thermal Energy:** Heat energy (e.g., boiling water, sun's heat) - **Chemical Energy:** Energy stored in chemical bonds (e.g., batteries, food) - **Electrical Energy:** Energy from the flow of electric charge (e.g., power from a socket) 3. **Visual Aids:** Show images or flashcards of various energy sources and types. Discuss each briefly. ### Guided Practice (15 minutes) 1. **Hands-On Activities:** - **Battery Demo:** Use a battery-operated toy. Show how chemical energy in the battery converts to electrical energy, which then converts to kinetic energy (movement of the toy). - **Rubber Band Demo:** Stretch a rubber band and discuss its potential energy. Release it to demonstrate kinetic energy. 2. **Flashcard Activity:** Divide students into small groups and give each group a set of flashcards. Have them sort flashcards into renewable vs. non-renewable and label the type of energy associated with each image. ### Independent Practice (10 minutes) 1. **Worksheets:** Distribute worksheets with various scenarios and images. Students will identify the source of energy (renewable or non-renewable) and the type of energy depicted. 2. **Energy Source Drawing:** Students will draw their favorite source of energy and label it as renewable or non-renewable. ### Conclusion (5 minutes) 1. **Review:** Quickly recap what was learned about energy, its sources, and types. 2. **Questions:** Allow time for any remaining questions and clarify doubts. ### Assessment: - Participation in discussions and group activities - Completion and accuracy of worksheets and drawings ### Extension (Optional): 1. **Energy Hunt:** As a homework assignment, ask students to find three examples of energy being used at home and identify the source and type of energy. 2. **Video/PPT:** Show a short educational video or PowerPoint presentation on renewable and non-renewable energy sources. ### Cleanup (5 minutes) - Ensure all materials are collected and the classroom is tidy. --- This lesson plan should provide an engaging and educational experience for 3rd-grade students on the topic of energy, covering its sources and various types.
