Kavi Follows the Light
Kavi waves a torch around a dark room 🔦. "I can't see my toys when it's dark! But switch on the light and — there they are!" ✨ "That's because light bounces off my toys and into my eyes. Some things, like a window 🪟, let light go right through them. Others, like a book 📕, block the light and make a shadow. Let's investigate!"

A peek inside
Kavi shines a torch at a clear glass window 🪟. Does the light pass through, or is it blocked?
Clear glass is transparent, so light passes straight through it.
