Summer is a great time to learn about shadows and as my children are a little obsessed with contact paper at the moment we thought a shadow frame might be a fun idea.
What you’ll need
A sunny day
Cut the cardboard into a frame shape and stick contact paper on to one side.
Use your decorations to create a shape in the middle.
Take your frame outside and work out how to made a shadow.
Did you know a shadow is formed when an object blocks light. To block light an object must be opaque or translucent.
A transparent object will not make a shadow, as light passes straight through it.
Transparent materials let light pass through them in straight lines, so that you can see clearly through them.
Translucent materials let some light through, but scatter the light in different directions. We can not see clearly through translucent materials.
Opaque materials do not let any light pass through them.
The Sun makes the longest shadows at the beginning and end of the day, when it is is lowest in the sky.
The Sun makes the shortest shadows at midday, when it is highest in the sky.
Can you write down 3 examples of transparent objects, opaque objects and translucent objects?
Can you investigate how to make the shadow bigger and smaller?
Can you make a nature version using leaves and sticks or a weather picture?
