In this lab, you examined factors that influence the absorption of energy from [___]. You investigated how the [___] of material and the angle of [___] affect the absorption of heat. Finally, you looked at the result of temperature differences on Earth’s surface.

Insolation means incoming solar radiation—the energy Earth receives from the Sun. The lab examines how material color and the angle at which sunlight arrives affect heat absorption, so “insolation” fits the sentence. “Isolation” means separation, and “solation” is not the standard term here.
