Investigating Heat Transfer:

Convection

Students will observe the process of convection heat transfer.

Time

Collection Group

SOLAR COOKING

 

Standards

  • S3P1. Students will investigate how heat is produced and the effects of heating and cooling, and will understand a change in temperature indicates a change in heat.
    • c. Investigate the transfer of heat energy from the sun to various materials.

Materials

  • Cold blue-dyed water
  • Hot red-dyed water
  • Clear container; consider re-purposing glass jars, plastic cups or bottles
  • Funnel

Procedures

  1. Fill a clear cup with cold blue-dyed water. Use a funnel to introduce hot red-dyed water to the bottom of the clear container.
  2. Notice that the red water rises by convection then the water changes to purple as the heat energy is transferred from the warmer area to the colder area.
