#### Grade Level: 5th Grade
#### Subject: Science
#### Duration: 60 minutes
---
### Objective:
By the end of this lesson, students will be able to:
1. Define energy and its importance.
2. Identify different types of energy (kinetic, potential, thermal, electrical, chemical, and light).
3. Understand the basic principles of energy conservation and transfer.
### Materials:
- Whiteboard and markers
- Chart paper and markers
- Energy conversion diagrams (printed)
- Ball or toy car (for kinetic energy demonstration)
- Rubber band or spring (for potential energy demonstration)
- Batteries, wires, and a small light bulb (for electrical energy demonstration)
- Thermometer and ice cubes (for thermal energy demonstration)
- Chemical energy demonstration kit (simple experiments like baking soda and vinegar reaction)
- Projector or computer for displaying videos/animations
### Introduction (10 minutes):
1. **Engage**: Start with a question, "What is energy?" and let students share their thoughts. Write key points on the board.
2. **Explain**: Provide a simple definition of energy: "Energy is the ability to do work or cause change."
3. **Explore**: Explain why energy is important in our daily lives. Provide examples like moving cars, heating food, lighting homes, etc.
### Direct Instruction (20 minutes):
1. **Types of Energy**:
- **Kinetic Energy**: Energy of motion. Demonstrate using a ball or toy car.
- **Potential Energy**: Stored energy. Demonstrate using a stretched rubber band or compressed spring.
- **Thermal (Heat) Energy**: Energy that comes from the temperature of matter. Demonstrate with ice cubes and a thermometer.
- **Electrical Energy**: Energy from electric currents. Demonstrate using a battery and light bulb.
- **Chemical Energy**: Energy stored in chemical bonds. Demonstrate with a simple chemical reaction (e.g., baking soda and vinegar).
- **Light Energy**: Energy from light. Show examples like sunlight, flashlight, etc.
2. **Energy Transformation and Conservation**:
- Explain that energy can change forms but cannot be created or destroyed (law of conservation of energy).
- Show energy conversion diagrams (e.g., a flashlight converting chemical energy from batteries to electrical energy and then to light energy).
- Explain real-life examples like how eating food (chemical energy) allows us to move (kinetic energy).
### Guided Practice (15 minutes):
1. **Group Activity**: Divide students into small groups. Provide each group with chart paper and markers. Assign each group one type of energy to illustrate and provide examples of.
2. **Presentation**: Each group presents their chart to the class. Discuss and clarify points as needed.
### Independent Practice (10 minutes):
1. **Worksheet**: Hand out a worksheet that has different scenarios. Students need to identify the types of energy involved and describe the energy transformation in each scenario.
### Assessment (5 minutes):
- Review answers from the worksheet together.
- Quick quiz: Ask a few questions to check understanding (e.g., "What type of energy is stored in a stretched rubber band?" "Give an example of energy transformation involving electrical energy.").
### Closure (5 minutes):
- Summarize key points: Types of energy, energy transformation, and the principle of conservation of energy.
- Ask students to think of examples of energy transformation at home and share during the next class.
### Extension Activity:
- Assign a project: Have students create a poster or model showing an energy conversion (like a solar-powered vehicle or a wind turbine).
