Transparent, Translucent, Opaque Worksheet for First Graders

📚 Topic Summary

Everything around us lets light pass through in different ways! Some things, like clear glass, let all the light through – we call them transparent. Other things, like frosted glass, let some light through, but you can't see clearly through them – those are translucent. And then there are things like wood or metal that don't let any light through at all – we call them opaque. Let's learn more!
