Grade Four

Curriculum Outcomes involved: 

• Physical Science: Light
  • Optical Devices
    • Describe properties of light that have led to the development of optical devices that enhance our ability to observe
    • Compare and describe how light interacts with a variety of optical devices and construct an optical device that performs a specific function
  • Sources of Light
  • Plan an investigation and communicate questions and ideas with others about light emitted frm an object, its own or an external source
  • Light Radiates from a Source
  • Observe, demonstrate, and make conclusions about how light travels and is dispersed from a variety of light sources
  • Objects that Absorb, Transmit, and/or Reflect Light
  • Investigate and predict how light interacts with a variety of objects (including changes in the location, shape, and relative size of a shadow) in order to determine whether objects cast shadows, allow light to pass, and/or reflect light
  • Classify objects as opaque, transparent, or translucent
  • Make observations and collect information about the reflective and refractive properties of various materials of different shapes
  • Bending Light
  • Demonstrate and describe how a variety of media can be used to change the direction of light
  • Dispersion of Light
  • Demonstrate that white light can be separated into colours (dispersion) and follow a set of procedures to make and use a colour wheel

• Physical Science: Sound
• Sound Vibrations
  • Relate vibrations to sound production and compare how vibrations travel different through a variety of materials
