Materials and Resources:
Teacher Materials
Globe
Heat Lamp or Bare light bulb on stand- light bulb should be 100 watts or larger
Teacher preparation:Teacher will need to set up heat lamp and globe in a central and safe location so students can see the investigation.
Then, set up the following stations within the classroom:
Radiation- Have this information for students to read: "Radiation is the transfer of heat energy by electromagnetic wave motion. The transfer of energy from the sun across nearly empty space is accomplished primarily by radiation. Radiation occurs without the involvement of a physical substance as the medium. The sun emits many forms of electromagnetic radiation in varying quantities."
Give students the example of a radio. While it is playing, it emits radio waves and that is an example of radiation. Have students list other forms of radiation. Students will record answers in their science notebook. Optional the teacher can have a radio that students can listen to.
Conduction- Have the information from this link for students to complete. Students will need to highlight the examples of conduction and complete crossword puzzle.
Convection- With teacher assistance, students will observe convection taking place in the breaker. The teacher explain process of the heat rising and the creating of a convection cell.
Step 1 Teacher will turn off lights and turn on heat lamp. Teacher will explain to students the lamp represents the Sun and the Globe represents the Earth. Teacher will ask students the following questions:
What does the Sun provide the Earth?
How does that energy/heat transfer to the Earth?
How does the Earth's heat stay or Earth?
The teachers will inform students that energy is transferred in three different ways: radiation, conduction and convection and provide examples for each.
Radiation- UV waves
Conduction- touching a hot pot
Convection- air blowing through a vent
Step 2 Teacher will then divide students into groups to complete Heat transfer stations. Students will rotate through the stations that represent radiation, conduction and convection. Students will remain in stations for 15-20 minutes to complete tasks. Have students share out learning from the three stations. After rotations, the teacher will review the three heat transfers.
Step 3 Students will create a foldable with the three types of heat transfers. Students will need to place the name of the type of heat transfer, a definition and illustration for each transfer.
Assessment Strategies
The teacher will assess each student’s accuracy of the Heat Transfer foldable checking for the correct definition and example of heat transfer.
Students will place pictures in the correct category of Radiation, Conduction, or Convection.
Intervention:
With a small group, teacher will demonstrate the three types of heat transfers using the heat lamp and globe.
