Our topic this half term is Light.

Can you research:

• how light appears to travel in straight lines
• the idea that light travels in straight lines to explain that objects are seen because they give out or reflect light into the eye
• how we see things because light travels from light sources to our eyes or from light sources to objects and then to our eyes

use the idea that light travels in straight lines to explain why shadows have the same shape as the objects that cast them.
