### 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.
