Curriculum content descriptions

identify sources of light, recognise that light travels in a straight path and describe how shadows are formed and light can be reflected and refracted (AC9S5U03)

Elaborations
  • distinguishing between natural (such as glow worms, the sun and stars) and artificial (such as light bulbs or candles) sources of light
  • investigating the shadows that are formed when light is completely or partially blocked by an object, such as when using a sundial or shadow puppets
  • drawing ray diagrams to show how the path of light from a source reflects off surfaces into the eye
  • observing refraction of light using prisms or water droplets and examining the rainbow effect produced
  • exploring how holograph videos use the refractive properties of light to create an image that appears to be 3-dimensional
  • exploring the use of reflection of light by mirrors such as in periscopes and mirror mazes
  • recognising First Nations Australians’ understanding of refraction as experienced in spearfishing and in shimmering body paint, and reflection as evidenced by materials selected for construction of housing
General capabilities
  • Critical and creative thinking Critical and Creative Thinking

Outdoor Shadows

This activity invites students to explore how outside shadows changes over time and relate this to the movement of the Sun and Earth. Students are asked to go outside and trace an outline of their shadow, wait a while, try again, and observe and record how their shadow has changed. The activity includes a list of tools ...

Shadows

This activity invites students to explore the phenomena of shadows and investigate the question, 'How can you change shadows?' Students work with shadow phenomena outdoors, indoors, or both to figure out how to change the size, shape, and position of a shadow. The activity is designed for use at home or in a classroom and ...

The physics of invisibility cloaks

Could an invisibility cloak actually work? Prashanth and Maria from MIT explore this idea and demonstrate the cool ways that light bounces, bends and mixes. How do the wings of the Morpho Butterfly give clues about how an invisibility cloak could work? How would light need to be channelled in order for something to seem invisible?

Elliot and the Surfing Scientist: Red cabbage pH experiment

It might sound 'un-sciencey', and have a bad smell, but red cabbage is actually very useful for testing the pH of liquids. Added to well-known liquids like lemonade or vinegar, red cabbage juice changes to 'pretty colours'. In this clip, Surfing Scientist Ruben Meerman explains the colour changes and how red cabbage juice ...
