Notice & predict
Draw the shape you expect
Sketch a remembered bow and predict colors.
Curiosity Bundle
Why Does a Rainbow Curve?
A bow in the sky. A band on paper. What makes those colors appear?
Begin with a shape your child remembers. Separate colors indoors, then explore why droplets show a bow around the direction of your shadow.
IgniteCould you walk to the end?
Offer one puzzle and leave room for a first idea.
Offer one puzzle. Leave room for a guess.
Invite your child to draw a rainbow from memory. Ask, "If we walked toward its end, what do you think we would find?"
Another way to begin
Show a clear bottle of water and white paper. Ask, "Could plain water help put colors on this paper? What would we need to try?"
Use the bottle puzzle indoors. A natural rainbow is not needed to begin.
KindleDraw the shape you expect
Look, guess and sketch before reading. Keep the first version.
ReadFollow light a little further
Both readings are part of the exploration. Read together or across short sittings.
DoChange one thing and compare
Try both investigations when conditions allow. Record surprising or missing results honestly.
CheckReturn to your first idea
Revisit both readings and the evidence. Parent answers support a conversation.
A light check
What would you change now?
Revisit light paths shape and model limits.
