Does light travel in straight or wavy lines?

This week year 6 have been investigating how light travels.  Through practical
investigations it was decided that light travels in a straight line not a wavy
one.  We see a reflection when the beams of light travel in straight lines to
our eyes.  Next week in science we are going to be making periscopes and
investigating how they were used in World War 1.  Don’t forget to bring
your Pringles tins in for the Pin Hole cameras later in the term.
