In this unit, we will learn how light travels and how this enables us to see objects. We will be finding out about mirrors and the angles of reflection and incidence. We will work scientifically and collaboratively to investigate refraction, carrying out some experiments into the effects of bending light. We will work in a hands-on way to explore how light creates the colours we see.
- I can show that light appears to travel in straight lines.
- I can explain that light travels in straight lines and that objects are seen because they give out or reflect light into the eye.
- I can demonstrate and 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.
- I can demonstrate that light travels in straight lines to show why shadows have the same shape as the objects that cast them.
