Science KS 2 Unit 6F How we see things (short unit)

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

This unit takes approximately 6 hours.
