Demonstrations in Phyiscs at UBC
Class of 2009
Welcome to the Human Lens.
This demonstration is designed for students in either grade 11 or 12. There are links for both teachers wishing to use this demonstration and students exploring the demonstration themselves!
The main purpose of this demonstration is to teach students about optics. The Teachers link and the Students link each have appropriate PowerPoint slides providing vital information on optics. The slides also correspond to the actual demonstration.
The demonstration consists of a light source, an accommodating lens, and a screen. By using a lens that has the ability to change its focal length, students can learn about accommodation focus used by the human lens. Students will also learn about common vision problems such as presbyopia, hyperopia, and myopia and how the use of lenses can correct these problems.
Please note: the PowerPoint slides are viewed best in Internet Explorer.
