Creating a periscope working model using cardboard and mirrors is an excellent educational project.
Here’s a step-by-step guide:
- Cardboard sheets (2)
- Mirrors (2)
- Craft knife or scissors
- Craft glue or hot glue gun
- Decorative materials (optional)
- Small object to observe (optional)
- Prepare the Cardboard Pieces:
- Cut out four rectangular pieces from the cardboard. Two pieces should be larger and will serve as the periscope’s body. The other two should be smaller and will be used for the periscope’s top and bottom.
- Cut Openings for Mirrors:
- In the larger cardboard pieces (the body of the periscope), cut out square openings near the top. These openings should be just big enough to snugly hold the mirrors.
- Insert Mirrors:
- Place one mirror into each of the square openings you made. Ensure that they are positioned at a 45-degree angle to the cardboard, so they reflect light.
- Create the Tube:
- Join the two larger cardboard pieces together, forming a rectangular tube with the mirrors inside. Use tape or glue to secure them in place.
- Attach the Top and Bottom Pieces:
- Attach the smaller cardboard pieces to the top and bottom of the tube using glue or tape. This will help stabilize the periscope.
- Decorate (Optional):
- Use colored paper, paint, or other decorative materials to customize the periscope.
- Align the Mirrors:
- Adjust the mirrors so they are facing each other, allowing light to bounce between them.
- Test Your Periscope:
- Look through one end of the periscope while holding it up. You should be able to see objects that the periscope is facing.
- Optional Object Observation:
- Place a small object in front of the periscope and observe it through the eyepiece.
Your periscope working model is now complete! This project demonstrates how mirrors can be used to change the direction of light and allows for viewing objects that are not directly in your line of sight. It’s a fun and educational way to learn about optics.
