        Energy | Essential Lens

        The photographs in this collection illustrate the impact of energy as movement, light, or heat; others show mechanisms engineered to capture, store, and distribute energy. Ask students to consider the costs and benefits of different energy-capturing systems. In addition to the physical science concept of energy, science, and engineering topics directly and indirectly related to the photographs, include natural resources, human impact on earth, and defining and delimiting engineering problems.
