Exploring Thermal Energy Concepts

What materials are required for the thermal energy glow lab?

• Cold water, hot water, glow sticks, and a clear glass

• Cold water, hot water, glow sticks, and a metal container

• Cold water, hot water, glow sticks, and a plastic cup

• Cold water, hot water, glow sticks, and a ceramic mug

Why is hot water kept in a thermos for the experiment?

• To keep it from evaporating

• To keep it at room temperature

• To keep it hot

• To keep it cold
