Optics Project: Shadow Puppets

As we explained in our blog post titled 'Introduction to Optics', the study of light is commonly referred to as optical science. Making shadow puppets is a fun and creative way to experiment with lights and shadows. This project can be done using natural light or artificial light. Here is a list of materials you will need in order to make shadow puppets:

• Construction paper or cardboard
• Glue or tape
• Scissors
• Pencil or Pen
• Popsicle sticks or straws

First thing to do is decide what type of puppets shadow puppets you will make. Shadow puppets can be something as simple as basic shapes to more complex things like animals and people. If you are planning a shadow puppet show, decide what characters, shapes or objects you will be creating.

Next you will need to draw out your puppets on the construction paper or cardboard. It is a good idea to use paper that is hard or stiff in nature so will have nice sturdy shadow puppets. After you've drawn an outline of your puppet, use your scissors to cut it out. Carefully cut along the lines that you've drawn. The next step is to glue or tape the cut out to the Popsicle stick or straw.

You can add decorations to your creation for fun. Although decorations such as colors and glitter will not be visible in the shadow, it may be fun to do. You can also make more complex and creative puppets by cutting designs into your puppets. Cutting wholes, or shapes in your puppets allows light to shine through, creating a design.
