How did the lab activities help you answer the lesson question "How do the processes of conduction, convection, and radiation help distribute energy on Earth?" What did you learn from conducting this lab?
The lab activities demonstrated that heat energy is transferred in three distinct ways. I learned that conduction occurs through direct contact, such as heat moving through aluminum foil. Convection transfers energy through the movement of fluids, which I observed in water. Radiation transfers energy through electromagnetic waves, as shown by the heat from the light bulb reaching the paper. Together, these processes explain how solar energy reaches Earth and is redistributed through the atmosphere, oceans, and land.
Sample Response: In the lab, I conducted three experiments. In each experiment, energy in the form of heat was transferred in a different way. Energy can be transferred through a material like aluminum foil through conduction. In water, energy is transferred through convection. Energy can travel from the light bulb to the paper through radiation. I learned that conduction can move energy between Earth’s materials, convection can transfer heat through Earth’s waters, and radiation can transfer he
