Shadow Lengths

 

This week we tried to work out why the length of a shadow changes  throughout the day.  We already knew that shadows are formed when the sun light  is blocked by an opaque object.

We organised an observation experiment .  We decided that the block would represent a building and the torch the natural source of light that is the Sun. We noticed that the shadow of the block was longer when the torch was on lying on the table and very small when the torch was shone above the block.  All depended on the angle of the light and the surface area where the light hit the block.
