Lesson Title: Heat Energy

Grade Level: 4th Grade

Objective: Students will be able to understand the concept of heat energy and its sources.

Materials: - Whiteboard and markers - Heat energy worksheet - Heat sources pictures - Thermometer - Hot water - Ice cubes - Candle - Matches

Introduction: Begin the lesson by asking students if they have ever felt hot or cold. Ask them what they think causes these feelings. Explain that heat energy is the energy that makes things feel hot. It is also the energy that makes things change from a solid to a liquid or a liquid to a gas.

Direct Instruction: 1. Discuss the different sources of heat energy such as the sun, fire, electricity, and friction. 2. Show pictures of different heat sources and ask students to identify them. 3. Explain that heat energy can be measured using a thermometer. 4. Demonstrate how to use a thermometer by placing it in hot water and cold ice cubes. 5. Discuss the different states of matter and how heat energy can change them. For example, heat energy can melt ice into water and water into steam. 6. Show a candle and light it with matches. Explain that the heat energy from the flame is what makes the candle melt and produce light.

Guided Practice: 1. Distribute the heat energy worksheet to students. 2. Have students identify different sources of heat energy and draw pictures of them. 3. Ask students to write a short paragraph about how heat energy can change the state of matter.

Independent Practice: 1. Divide students into small groups. 2. Provide each group with a heat source such as a candle or a lamp. 3. Have students observe the heat source and discuss how it produces heat energy. 4. Ask students to write a short paragraph about their observations.

Closure: Review the concept of heat energy and its sources. Ask students to share what they learned during the lesson. Encourage them to think about how heat energy affects their daily lives.
