Shedding light on light. Shedding light on lenses

Description

After a quick recap on refraction, students will learn how magnifying glasses work and how projectors produce giant images on giant cinema screens. We then look into a tuna fish's eye to show how our eyes work. After explaining how concave lenses produce images, well learn how spectacles help people who have vision defects. The first bonus feature takes a fun look at slow motion, fast motion and stop motion and the second bonus feature, aimed at more advanced students, covers the mathematics of lenses and image formation.
