Does light travel in straight lines?

Year 2 and 3 have been investigating how light travels in science lessons this week. We have previously discovered what a light source and a reflector are and used our prior knowledge to test how light travels.

The children used card cutouts, mirrors and torches to test whether light travels in straight lines. We concluded that yes, light does travel in straight lines!

Some of us tested what happened when light hit flat and rough surfaces. We found out that flat surfaces, such as a mirror, reflect the light best whilst rougher surfaces (scrunched up tin foil) cause the light to scatter.
