The properties and behaviour of light have fascinated people throughout the ages. Though much has been learned about the way in which light behaves, its fundamental nature remains a mystery.
This unit is perhaps the most important one in Physics 20. It begins with
a consideration of some important characteristics of light. Applications should
be referred to regularly in the unit
.
Geometric optics form the main components of the unit. Many opportunities should
be provided for students to investigate the properties and behaviour of light.
An extension of ideas based on Core Unit I dealing with the physics of everyday things can help to put the study of light within a relevant context for further investigation. Teachers should feel free to experiment in modifying the sequence of presentation of material, as well as attempting alternative instructional approaches and student assessment techniques.
In this unit students will increase their abilities to:
Give some examples from common experiences which illustrate the behaviour of light.
Perform activities to investigate the behaviour of light.
Apply the physical laws which govern the behaviour of light in solving problems.
Appreciate the importance of experimentation in science.
Classify ideas and information.
Recognize the importance of observation in science.
Appreciate that science is a human endeavour.
Recognize that the historical progression of scientific ideas, along with the development of new technolo- gies, have helped to bring about new advances and discoveries.
Distinguish between fact and opinion.
Recognize that diverse solutions might be available for solving specific problems.
Describe some of the important differences that exist between science and technology.
Recognize that scientific and technological achievements represent creative and artistic forms of human expression.
Recognize that an interest in science and technology can lead to a number of exciting careers or hobbies.
Recognize that equal opportunities are available in the pursuit of science and technology, regardless of gender, race, or religion.
Recognize key information that might need to be obtained to investigate a particular problem, develop search criteria to access the information, scrutinize the information carefully, and use it wisely to further knowledge, understanding, and peace.
Use a wide range of possibilities for developing knowledge of the major concepts within physics. (COM)
Strengthen their understanding within physics through applying knowledge of numbers and their interrelationships. (NUM)
Promote both intuitive, imaginative thought and the ability to evaluate ideas, processes, experiences and objects in meaningful contexts. (CCT)
Develop an understanding that technology both shapes society and is shaped by society. (TL)
Treat themselves and others with respect. (PSVS)
Meet their own learning needs. (IL)
