By the end of this unit, students will be able to:
- explore the concept of how humans see objects;
- identify that light travels in straight lines;
- recognize that light can change direction when reflected from an object;
- draw simple ray diagrams to explain how light travels in straight lines from a light source to an object and is then reflected to the eye.
Curriculum Alignment: Year 6 Science: Light:
- recognise that light appears to travel in straight lines
- use the idea that light travels in straight lines to explain that objects are seen because they give out or reflect light into the eye
- explain that we see things because light travels from light sources to our eyes or from light sources to objects and then to our eyes
