Comparing Different Types of Light Bulb

Intended Learning Outcomes

The students will be able to:

  • apply their understanding of light emitting processes to explain the way a range of light bulbs function
  • make valid comparisons between different types of light bulbs
  • determine what they consider is the most environmentally friendly light bulb
  • use a range of reference sources to obtain information about light bulbs and light emitting processes
  • describe some current lighting research (optional extension).

Teaching Rationales

In this inquiry activity students investigate the main light-emitting processes, how they work, and which processes are used by which types of light-bulbs. The students compare the types of light bulb available to consumers.

Learning Areas, Strands, Achievement Objectives

7 - 8 Science

Physical World
Physical inquiry and physics concepts

  • Students will investigate physical phenomena (in the areas of mechanics, electricity, electromagnetism, light and waves, and atomic and nuclear physics) and produce qualitative and quantitative explanations for a variety of complex situations.

Using physics

  • Students will use physics ideas to explain a technological, biological or astronomical application of physics and discuss related issues.
  • Students will analyse and evaluate data to deduce complex trends and relationships in physical phenomena.

Participating and contributing

  • Students will use relevant information to develop a coherent understanding of socio-scientific issues that concern them to identify possible responses at both personal and societal levels.
