"Serving the Universe on a Paper
Plate"
Activity: Rainbow Finder II
Make a simplified Rainbow
Finder from paper plate Rainbows.
Make a rainbow by spinning a plate on a turntable while holding a colored
marker on the plate, as shown in the Rainbow
Turntable activity.
From the outer edge the colors are remembered by the mnemonic aid "Roy G.
Biv," which stands for the colors red, orange, yellow green, blue, indigo,
and violet.
When completed, the bows can be folded into free-standing designs.
Outside on a sunny day, ask the children in which direction they
should look to see a rainbow, if it were raining at that moment. Reinforce
that it is dangerous to look directly at the sun, for eye damage may
result.
With a garden hose, spray a fine mist first toward the direction of the sun
while the children stand behind you. Slowly sweep the mist around in a
large circle, continuously asking them to call out when they spot the
rainbow. The rainbow should appear when their backs are to the sun.
Note how rainbow finding is an eye-friendly activity, for the colorful arcs are
opposite the harmful rays of the sun.
 To find the rainbow using the Rainbow
Turntable plates, look down along the trough of the plate at the
crease. Position it so you see the shadow of your head at the other end.
 When you see your head's shadow in the trough, without moving the plate look up
between the V of the two plate halves for the rainbow.
Rainbow found!
Notice how a low sun produces a high rainbow, and
vice versa. The largest bows are at sunrise and sunset, while midday the rainbow
may appear so low it is in the foreground, below the horizon.
