Original video credit: IG/@braganca_cris. This whiteboard sundial demonstration turns a classroom board into a hands-on astronomy experiment, helping students understand how sundials measure time using sunlight and shadows. A hand-drawn clock dial, a central pointer rod, and a smartphone flashlight recreate the basic principles of solar timekeeping. This simple physics demonstration makes the connection between light, shadow movement, and time measurement easy to see. The setup works by using the flashlight as an artificial light source and the pointer rod as a gnomon, the part of a sundial that casts a shadow. When the light source changes position or angle, the shadow moves across the numbered dial, illustrating how the apparent position of the Sun determines a sundial’s reading. In a real sundial, the Sun’s apparent daily movement across the sky results primarily from Earth’s rotation. The classroom model makes this relationship visible without waiting for daylight or tracking the actual Sun. For STEM educators, DIY science enthusiasts, and hands-on learners, this homemade sundial offers a simple way to explore astronomy, geometry, and the physics of light. By combining a smartphone flashlight with a basic pointer and a marked dial, the experiment demonstrates how ancient timekeeping devices use the predictable relationship between light and shadow. It is an accessible classroom project for anyone curious about how sundials work and how Earth’s rotation connects to measuring time. No copyright infringement intended.
