Show transcript
Shadows are formed when the light from a light source is blocked by an object.
The size of a shadow changes depending on the distance of an object from the light source.
Scientists ask questions and then plan how to carry out the right type of investigation to find answers.
A fair test investigation is when only one thing is changed and another is measured. All other things are kept the same.
