Exploring Thermal Energy Transfer: Conduction and Convection

The video tutorial covers a lab on thermal energy transfer, focusing on conduction and convection. It begins with an introduction to the materials needed, followed by a detailed conduction experiment using aluminum foil and wax chips. The second part explores convection with a lava lamp and a cooktop. The video concludes with a summary of the experiments and a preview of the next parts.

Which of the following is NOT a required material for the thermal energy transfer lab?

• A stove or electric cooktop

• A lava lamp

• A thermometer

• A plastic container
