Optional Unit VIII: Atomic Physics

Unit Overview

The use of nuclear energy in society is certainly one of the most widely debated and probably one of the most widely misunderstood topics in physics today. The public understanding gap needs to be addressed, so that scientifically literate people will be able to make well-informed decisions regarding the use of nuclear energy. It could be argued that an understanding of nuclear energy is a basic requirement for all students.

In order to be able to make such informed decisions, people need a solid knowledge base upon which to form opinions. This Optional Unit is intended to provide students with a further extension of Core Unit IV.

A broader base of knowledge and information will enable students to form opinions and debate the use of nuclear energy.

Research in modern physics is continuing. Topic E, contemporary physics, allows teachers and students to examine some of this research further. Because of the current, ongoing nature of this topic, it is one which is best developed independently, by teachers and students. Some guidelines are provided, but beyond that teachers are free to develop section E based on their own interests.

Foundational Objectives for Physics and the Common Essential Learnings

In this unit students will increase their abilities to:

Recognize that physics is an ongoing human endeavour.

Recognize the need to remain informed on current research in science.

Realize that scientists need to inform society of any real or potential abuse of science.

Appreciate that research is still needed into the uses of nuclear energy.

Recognize that people are constantly being exposed to various forms of radiation.

Recognize that, although exposure to radioactivity is inevitable, it should be minimized.

Recognize the potential hazards associated with exposure to certain types of radiation.

Assess whether or not certain positions regarding the use of nuclear energy are based on a good understanding of physics.

Recognize the need to become informed about the facts and issues surrounding the use of nuclear energy.

Understand the personal, moral, social, and cultural aspects of physics. (PSVS)

Use a wide range of possibilities for developing their knowledge of the major concepts within physics. (COM)

Develop as "strong sense" critical and creative thinkers. (CCT)

Become actively involved in decision-making related to technological developments. (TL)

Develop a positive disposition to life-long learning. (IL)
