You will need a number of sources of light, such as table lamps, for this activity.

Start with one lamp and sit someone with their back to it.

The task is to place the other lamps so that the person casts as little shadow as possible.

Now get a large sheet of white card and move it about. The card bounces light and so can also help to get rid of shadows. See if you can use one light source and several cards to get rid of shadows, too.
