Objectives
When you have completed the following sections of the Light and Optical Systems unit you will be able to:

1.0 Our knowledge about light and vision comes from explanations, inventions, and investigations.
  • identify challenges in explaining light and vision
  • analyze how microscopes, telescopes, and other optical devices use the properties of light
  • describe how the development of optical devices contributed to other discoveries in science
  • investigate light beams and identify phenomena that show the nature of light
2.0 Light behaves in predictable ways.
  • describe how light is reflected, transmitted, and absorbed
  • identify materials that are good absorbers, reflectors, and transmitters of light
  • measure and predict angles of reflection and refraction
  • describe how the refraction of light varies through different materials
  • demonstrate the formation of images using a convex lens
  • _
3.0 Light is part of the electromagnetic spectrum and travels in waves.
  • describe the characteristics and composition of sunlight
  • explain the wave properties of light and the electromagnetic spectrum
  • describe some of the technological applications of electromagnetic radiation
  • recognize the dangers associated with certain forms of radiation
  • evaluate, compare, and contrast different artificial and natural light sources
  • describe how primary colours can be added to produce different colours and white light
4.0 Eyes and cameras capture images using the properties of light.
  • explain how objects are seen by the eye
  • describe the similarities and differences between eyes and cameras
  • compare the function and design of mammalian and other vertebrate and invertebrate eyes
  • investigate new technologies that enhance human vision
  • describe how digital images are created, stored, and transmitted
