How to make your own shadow? Simple science for Grade 1.

📚 What is a Shadow?

A shadow is a dark area or shape produced when an object blocks light. Imagine sunlight shining on you – if you stand in its way, you create a shadow on the ground!

📜 History of Shadow Science

People have been observing shadows for thousands of years! Ancient civilizations used shadows to tell time with sundials. Understanding shadows helped them with navigation and even building structures.

💡 Key Principles of Shadow Formation

• 🔦 Light Source: Shadows need light! The sun, a lamp, or even a candle can be a light source.
• 🛑 Opaque Object: Opaque objects block light. You can't see through them! This is what creates the shadow.
• 🏞️ Surface: Shadows appear on surfaces like walls, floors, or the ground.
