What do you need to make a shadow?

To make a shadow you need:

1.    Light
2.  Object
3. Surface

What kinds of objects make shadows?

The kinds of objects that make shadows are opaque objects, like: watermelons, people, cats, shells, and more... 

Transparent objects, like clear glass, will not make a shadow.

What kinds of lights are there?

Some light sources are: sunlight, moonlight, flashlights, lamplight, light bulbs, and fire (candles).

How does a shadow move?

 A shadow moves if the object moves (like shadow puppets) or if the light moves.

Can you make a shadow bigger or smaller?

 You can make a shadow bigger by moving the object closer to the light.

You can make a shadow smaller by moving the object away from the light.

Can you make a shadow darker or lighter?

 You can make a shadow darker by having a bright light.

You can make a shadow lighter by having a dim light.

 A shadow is the longest in length early and late in day when the sun is low during the sunrise and sunset.

What is the difference between a shadow early or late in the day and a shadow in the middle of the day?

 A shadow early in the day (sunrise) and late in the day (sunset) is really long.

A shadow in the middle of the day is really short because the sun is high above you.

To investigate this, our class went outside to observe how shadows are different throughout the day.

We traced our shadows at 8AM, at Noon time, and at 3 PM.  Students were paired up with a partner.  One partner traced the shadows while the other one was the statue.  Both colored in the shadows.

Where is the shadow going to be if the light is in behind you?

 If the light is behind you, the shadow will be in front of you because the shadow is always on the opposite side of the object from the light.
