Light experiment with a shadow
 
Seeing Shadows

Materials you will need:

• Sunny Day
• Night Sky

What happens when light hits an objects?

 

 
When light hits an object, the light will either pass through it, be absorbed by it or bounce off it.

Steps:

1. Go outside on a really nice sunny day.

2. Find a nice sunny spot to stand.  Make sure you find an open area where there are no objects such as buildings or trees in the area.

3.  Locate the position of the Sun in the sky and turn away from it so that your back is to it.

4.  Look for your shadow in front of you.

5.  Record the time and write what your shadow looks like.  Is it a long shadow or is it and short shadow.

6.  Go outside to the same position a few more times in the day and record the time and observation of your shadow.

7.  Be sure to go outside in the evening when the Sun has set and look for your shadow.  Record your findings.

If the Sun is low in the sky your shadow will look long.
If the Sun is high in the sky your shadow will look short.

Transparent materials will allow most of the light to pass through it.  Clouds in the sky allow light to pass through them but we cannot see through them.

Translucent materials will allow light to pass through it. Sunglasses allow us to see through them.

Opaque materials will not allow any light to pass through it.  Your body is an opaque object that does not allow light to pass through it.
