Horizontal Sundial DIY

Description
In this video, students build a Horizontal Sundial DIY model and learn how people measured time using the Sun before clocks were invented. Through this activity, students observe how the Sun’s movement creates shadows and how these shadows help tell time. This hands-on model connects astronomy, Earth’s rotation, and timekeeping in a fun and easy way. A perfect activity to understand ancient science with real-world observation!
Learning Objectives
