As part of the Spaceship Earth Unit in Mystery Science, Mrs. Lang's fifth-grade class explored why our ancestors divided the day into hours and how clocks track the Sun's apparent movement. They created sundials to understand this concept. Initially, students used flashlights indoors to see how the light's position influences the time displayed on a clock. Afterwards, they took their shadow clocks outside to observe how the Sun's position reveals the time of day.
