What Is a Shadow?A shadow is formed when an object does not allow the light to pass
through it.
What Direction Does Light Travel?Light travels in straight lines.
How Are Shadows Made?Shadows are made when there is an object blocking the
light from hitting the surface.
The object needs to be a solid and opaque. Opaque
means it will not allow light to travel though it.
If it is clear then the sun will pass through it,
whereas a solid object will block it.
This means that the shadow will
always be on the opposite side
of an object to the
sun or light.

Complete section A on your PDF provided.Fill in the missing words and then write your prediction about what you think will happen.
ActivityIn the morning, place a toy or model on some paper and draw around it. DO NOT MOVE THE MODEL OR PAPER!! Leave it in the same spot and return to it at lunchtime.At lunchtime draw around the shadow again, you will hopefully see that the shadow has moved. Again, DO NOT MOVE ANYTHING! Leave it all out until teatime.At teatime draw around the shadow for one last time. Again it should have moved.
Record the times on your PDF (section B)Remember to label your drawings.
Alternative activityRather than drawing around a model you might want to get someone in your family to draw around you! Draw around your feet with chalk – this will be where you need to stand each time.Ask someone in your family to draw around your shadow in the morning, lunchtime and at teatime.
