Lab: Energy Transfer

Question 1

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?

Revolt · Accepted Answer

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.

Question 2

What did you include in your response? Check all that apply.

Revolt · Accepted Answer

Conduction transfers heat between two materials that are touching, such as foil and chocolate pieces, or particles, such as the atoms in foil.; Convection allows heat to be transferred in liquids, like water.; Radiation transfers heat from a light bulb to paper.; Conduction, convection, and radiation move energy from the Sun to Earth and throughout Earth.
