In this unit children learn that mirrors and shiny surfaces alter the direction in which light travels and that when they see objects, light enters the eye. Children contrast reflection and shadow formation.
Experimental and investigative work focuses on:
- planning and carrying out a fair test
- making observations and measurements
- recognising when to repeat measurements
- presenting results in line graphs
- identifying patterns in data.
Work in this unit also offers opportunities for children to relate their understanding of light, reflection and shadow formation to everyday phenomena.
Visually impaired children will need particular support in this unit. They will be able to take part through careful use of residual vision, through their awareness that many light sources are also heat sources and through their sense of touch. It is important for teachers to help children to be sensitive to those who are visually impaired.
This unit takes approximately 6 hours.
