How to explain light spectrum to an 8yo?

Recommended Posts

I haven't used Apologia but my son understood light spectra better after we got a prism and he saw how the light broke into different colors.


:iagree: exactly this.


Don't tell him, show him. Pick up some prisms and allow him to goof around with them. Let him discover on his own that they make rainbows and then discuss when/where he is able to make rainbows. He will pick up that it only happens in direct light, and that will give you the opportunity to remind him about what you read in Apologia.


Fun stuff!
