Free 7th Grade Heat, Temperature, And Heat Transfer Lesson Plan (Science)

Topic: Heat, Temperature, and Heat Transfer

Objectives & Outcomes

• Students will be able to define heat and temperature and explain their relationship.
• Students will be able to do an experiment to measure the amount of heat transferred by different objects.

Materials

• Thermometers (one for each student)
• Ice cubes
• Hot water
• Small pieces of paper
• Aluminum foil
• Ungloved hands (optional)
• Timer

Warm-Up

• Ask students if they have ever felt hot or cold.
• Ask them to describe the hot or cold sensation and how it feels.
• Ask them if they know what causes the hot or cold sensation.
• Ask them if they know how temperature is measured and if they know the unit of temperature.

Direct Instruction

• Introduce the concept of heat and temperature.
• Define heat as the energy that is transferred due to a difference in temperature.
• Define temperature as the measure of the hotness or coldness of a substance.
• Explain how to measure temperature using a thermometer.
• Demonstrate how to use a thermometer to measure the temperature of a liquid or a gas.

Guided Practice

• Give the students small containers with water and tea bags.
• Show the students how to measure the temperature of the liquid using a thermometer.
• Have the students record the temperature of the liquid in a chart.
• Have the students compare the temperature of the liquid to the tea bag.
• Have the students explain why the difference in temperature exists.

Independent Practice

• Have the students conduct an experiment to measure the rate of heat transfer.
• Give the students small containers with water and colored water.
• Have the students measure the temperature of the colored water and the water separately.
• Have the students add the colored water to the water, and record the temperature of the colored water and water mixture.
• Have the students compare the temperature of the colored water and water mixture to the temperature of the plain water.
• Have the students explain why the difference in temperature exists.

Closure:

• Review the main points of the lesson.
• Ask the students to share their findings from the experiment.

Assessment:

• Observe students during the independent practice to assess their understanding of the concept.
• Collect and review their reports for correct understanding and application of the concept.
