Color Wheel Questioning
This questioning would take place after the students made their first disc and tried to spin it.
Q: Why did you choose those colors?
A: “Because they are the lightest and we need to get white.”
Q: How did that result compare to Jonny’s whose colors were darker?
A: “He got a similar reaction.”
Q: So, does it need to be only the lightest colors?
A: “No, because we got the same reaction.”
Q: What if you use a mixture of dark and light colors?
A: “Maybe we’ll get closer to white.”
Q: So this got you closer, why is that?
A: “Because it’s the more colors you add, the closer to white you get.”
I would then have the students try again to make a disc that creates white.
