Mahmoud asks to use the light box in class. We see our own heads and Mohamed and Malak try drawing. When someone goes in front of the light everyone shouts!!! We shout because we can't see our shadow any more. The person is blocking the line of light going from the bulb to the whiteboard. We find out:-
* Light cannot travel through our bodies!
* The light source is behind the person making the shadow.
* Our bodies block the light - this makes the shadow.
We can use the overhead projector to find shadows, draw our profiles and change the colour of the light.
Now we decide to go outside to look for some reflections.......
Challenge:- One of these photos is the 'odd one out'
Can you find it and say why?
