Free 10th Grade Heat Enthalpy Lesson Plan

Topic: Heat Enthalpy

Objectives & Outcomes

• Students will be able to apply the concept of heat enthalpy to understand the energy changes occurring inside a device under constant pressure.

Materials

• A device under constant pressure (e.g. a pressure cooker, pressure cooker, pressure thermos)
• Calorie thermometer
• Calculator
• Pen and paper

Warm-up

• Ask students if they have ever used a pressure cooker or a pressure thermos before. Ask them to share their experiences and explain how these devices work.
• Next, show the class a calorie thermometer and explain how it is used to measure the temperature of a substance. Ask them to give an example of a situation where they might need to measure the temperature of a substance.

Direct Instruction

• Introduce the concept of heat and explain that it is a form of energy that is transferred by the movement of particles.
• Discuss the concept of enthalpy and explain that it is a measure of the amount of heat contained in a substance at a given temperature and pressure.
• Demonstrate how to use a pressure device to measure the enthalpy of a substance.

Guided Practice

• Have students work in pairs to conduct a series of experiments using the pressure device to measure the enthalpy of different substances at different temperatures.
• Have the students record the results of their experiments on the provided worksheets.

Independent Practice

• Have students use the data they collected during the experiments to create a graph that shows the relationship between enthalpy and temperature for the substances they tested.
• Allow students to use their graphs to make predictions about the enthalpy of other substances at different temperatures.

Closure

• Review the definition of enthalpy and how it can be determined using an equation or a graph.
• Ask students to share their predictions about the enthalpy of other substances at different temperatures and discuss any discrepancies between their predictions and the actual values.

Assessment

• Observe students during the independent practice activity to assess their understanding of the concept of heat enthalpy and their ability to apply it to a real-world situation.
• Review the students'reports for accuracy and completeness.
• Administer a quiz to assess students' understanding of the concept of heat enthalpy and their ability to apply it to a real-world situation.
