Lesson Title: Heat and Temperature

Grade Level: 4th Grade

Objectives: - Students will be able to define heat and temperature. - Students will be able to differentiate between heat and temperature. - Students will be able to identify sources of heat. - Students will be able to explain how heat is transferred.

Materials: - Whiteboard and markers - Heat sources (e.g. hot plate, candle, light bulb) - Thermometer - Ice cubes - Hot water - Cups - Handouts with questions and activities

Introduction: Ask students if they have ever felt hot or cold. Ask them what they think causes these sensations. Explain that heat is a form of energy that can be transferred from one object to another. Temperature is a measure of how hot or cold something is.

Direct Instruction: 1. Define heat and temperature on the whiteboard. 2. Discuss the difference between heat and temperature. Heat is the energy that is transferred from one object to another, while temperature is a measure of how hot or cold something is. 3. Identify sources of heat, such as the sun, fire, and electricity. 4. Explain the three ways that heat can be transferred: conduction, convection, and radiation.

Guided Practice: 1. Demonstrate conduction by placing a hot plate on a table and placing a cup of cold water on it. Ask students to observe what happens to the water. 2. Demonstrate convection by filling a cup with hot water and placing an ice cube on top. Ask students to observe what happens to the ice cube. 3. Demonstrate radiation by holding a hand over a light bulb. Ask students to observe what happens to their hand.

Independent Practice: 1. Distribute handouts with questions and activities related to heat and temperature. 2. Have students work in pairs or small groups to complete the activities. 3. Review the answers as a class.

Closure: Ask students to share one thing they learned about heat and temperature. Review the definitions of heat and temperature and the three ways that heat can be transferred.
