AC9S5U03
Physical sciences
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
Elaborations
- AC9S5U03_E1distinguishing between natural (such as glow worms, the sun and stars) and artificial (such as light bulbs or candles) sources of light
- AC9S5U03_E2investigating the shadows that are formed when light is completely or partially blocked by an object, such as when using a sundial or shadow puppets
- AC9S5U03_E3drawing ray diagrams to show how the path of light from a source reflects off surfaces into the eye
- AC9S5U03_E4observing refraction of light using prisms or water droplets and examining the rainbow effect produced
- AC9S5U03_E5exploring how 'holograph' videos use the refractive properties of light to create an image that appears to be 3-dimensional
- AC9S5U03_E6exploring the use of reflection of light by mirrors such as in periscopes and mirror mazes
- AC9S5U03_E7recognising 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
