In this engaging project, students will build a simple periscope using mirrors and a cardboard tube. This project will teach them about the reflection of light, angles, and how periscopes are used in real life. It's a fun and practical way to introduce young learners to basic principles of physics and optics.
If I position two mirrors at an angle in a tube, then I will be able to see an image from a different perspective.

Cut the cardboard tube to a length of about 10 inches.
Cut two small openings on opposite sides of the tube, about 2 inches from the top.
Place a mirror at a 45-degree angle in each opening using tape.
Ensure the mirrors face each other inside the tube.
Stand the periscope upright and look through the open end.
Test the periscope by placing it at different angles to see the reflected images.
Discuss how the angles of the mirrors affect the reflection.
Clean up and put away materials safely.
Students will be able to see an image from a different angle through the periscope, demonstrating principles of light reflection.
