Students gain a conceptual comprehension of the functioning of the Human Eye in relation to optics and optical vision correction. They explore optics with light sources and various lenses, relating these to visual acuity, accommodation, near point, blind spots, focal length, object/image distance as well as testing their vision with a Snellan Eye Chart.
Students explore the concept that not all light is visible to the human eye. Although UV light is not visible, it can still be harmful, causing sunburns or skin cancer. They use special beads to detect UV light around the school. Students then conduct an experiment to determine what types of materials are best for blocking UV light on Earth, as well as in space.
