3rd Grade

Hello Educators! Check out the lesson overview for our 3rd Grade Learning Power in-class field trip on heat transfer and insulators. Interested in us coming to your classroom?  Schedule a visit!

 

Georgia Standards of Excellence

Lesson Focus: Practice measuring temperature and explore heat transfer and how insulation affects changes in temperature.

S3P1. Obtain, evaluate and communicate information about the ways heat energy is transferred and measured.

a. Ask questions to identify sources of heat energy. (Clarification statement: Examples could include sunlight, friction and burning.)

 

Key Concepts:

  • Heat can be measured using a thermometer.
  • Heat energy can be transferred
  • Heat flows from hotter to cooler spaces
  • Insulators are materials that slow the flow or transfer of heat There are many ways to be energy efficient at home and at school

PARTS 1&3: CUP EXPERIMENT

Heat can be measured using a thermometer. Heat energy can be transferred. Heat flows from hotter to cooler spaces.

PART 2: ICE MELTING BLOCKS

Insulators are materials that slow the flow or transfer of heat.

PART 4: CONCLUSION

There are many ways to be energy efficient at home and at school.

 

Class Activities

Lesson Objectives:

  • Determine if a material is a good insulator.
  • Use a thermometer to measure heat energy.
  • Recognize the uses of electricity in everyday life

PART 1: CUP EXPERIMENT – BEGINNING TEMPERATURE

Materials:

  • 2 insulated cups
  • 1 lid
  • 2 thermometers
  • Data recording sheet

Purpose of Activity:

Use thermometers to measure the water temperature. Record the temperature of water in each cup and recognize that the cups are starting with water that is the same. Predict if the cup with or without the lid will better retain the water’s heat.

PART 2: ICE MELTING BLOCKS

Materials:

  • Ice melting blocks
  • Ice

Purpose of Activity:

Recognize that some materials are better insulators than others. Insulators slow the transfer or flow of heat, while conductors support the transfer or flow of heat at a faster rate.

PART 3: CUP EXPERIMENT – ENDING TEMPERATURE

Materials:

  • Revisit cup setup from Part 1 

Purpose of Activity:

Use the thermometers to measure the water temperature. Record the temperature of water in each cup and recognize that the cup with the lid has a higher temperature than the cup without a lid. Identify the lid as a good insulator

PART 4: CONCLUSION

Materials:

  • Activity Sheet – Lower half
  • Bright Ways to Save Energy In and Around your Home
  • Energy Efficiency Learning Map

Purpose of Activity

Compare the cups to your house. Heat is able to transfer through both big and small spaces. Determine the direction of heat flow.

Complete the fill-in-the blank: Review and put new obtained knowledge in action. Identify ways to energy efficiency is practiced. What are some ways that you can be efficient with energy? Can you find any of these on the Learning Map?
