The Golden Spiral Puzzle is a fun, hands-on activity that introduces students to the Fibonacci sequence and geometric patterns. Students repeatedly draw the largest possible square within the remaining rectangle, using its shorter side as a guide. They then connect quarter-circle curves to form a spiral. Finally, students colour and number the squares, exploring the relationship between mathematics, geometry, and patterns found in nature.

The Fibonacci Gauge is a hands-on STEAM activity that introduces students to the Fibonacci sequence, the Golden Ratio (1.618), and mathematical proportions. Students assemble a movable measuring tool using interconnected arms and pivot joints. By opening and closing the gauge, they can explore how the Golden Ratio remains approximately constant and compare proportions in everyday objects such as books, smartphones, and picture frames.

This project demonstrates a simple cardboard robotic hand that mimics finger movement using straws and strings. The cardboard forms the hand structure, the straws guide the strings, and pulling the strings bends the fingers like tendons in a real hand. It is a simple way to learn about robotics, joints, and human hand movement.
