Measuring Earth’s Radius Using Lego Bricks: A Novel Educational Approach
A remarkably ingenious and educational method has been developed to measure the Earth’s radius using the ubiquitous Lego building blocks. This innovative approach successfully translates complex physics principles into a hands-on experiment accessible to a wide audience, from children to adults. Its simplicity lies in its minimal requirements, eliminating the need for specialized equipment or vast terrains, making it feasible to experience the Earth’s scale conveniently at home or in a classroom.
The technique ingeniously combines the precise dimensions of Lego bricks with elementary surveying techniques that utilize the angle of sunlight. Participants measure the sun’s altitude at different locations simultaneously, and from this observed difference, they calculate the Earth’s circumference, and subsequently, its radius. This practical demonstration offers an engaging way to learn fundamental concepts in geometry, trigonometry, and astronomy, sparking curiosity and a deeper appreciation for science.
