Sundial

Human: 3D printing a sundial is an excellent way for kids to learn about our solar system, and the fascinating history of astronomy. From Aristarchus of Samos to Copernicus and Galileo, we can explore how ancient minds grasped the workings of the universe. Our sense of time is deeply connected to the earth's spinning motion, which changes as we orbit around the sun. A sundial is a device that closely mirrors these cycles, making it an ideal tool for understanding the earth's position in relation to the sun. The more kids know about the earth and its relationship with the sun, the better they'll be able to align their 3D design (parallel to the Earth's rotational axis) and even make adjustments for their specific geography. A sundial also tells another story: the history of time-telling. For thousands of years, people have been trying to create machines that can tell time accurately, from ancient sundials to modern electronic clocks. Kids can learn about the cultures of ancient civilizations (the Romans, the Druids of Stonehenge) by studying how they told time and see the progression of technology from the Egyptian sundials of 3,500 years ago to today's atomic clocks.
