Have you ever wondered how the lights in lighthouses are so bright? In this activity, students will examine a Fresnel lens to develop an understanding of how some lighthouse lenses work. They will then apply their knowledge of the lighthouse lens technology to imagine a new invention using a lighthouse lens to complete a different task. Included in an OurStory module from the Smithsonian's National Museum of American History entitled Life on the Water, this activity is intended to help children and adults enjoy exploring history together through the use of children's literature, everyday objects, and hands-on activities.
