Transcript of OPTICAL ILLUSIONS
We folded a piece of card stock in half and traced a round lid to make a circle.
How do you create an optical illusion???
We kept our paper folded and cut out our circle. We ended up with two circles the same size.
We made a list of pictures we could draw.
Kayley: cat eating a bowl of food
Deven: a hungry frog sitting on a lily pad waiting to catch a fly
Rafael: soccer ball going into the net
Nye'Jah: a pig playing in the mud
Isabella: a fish swimming in a bowl
We drew one part of our picture on each circle.
For example: Isabella drew a fish on one circle and a fish bowl with seaweed on the other circle.
We colored our pictures brightly using crayons.
We had to glue our circles back-to- back. We had to make sure that we flipped one circle so one picture faced upward and the other downward.
We punched holes on both sides of the circle, cut two pieces of string, and ties one through each hole in the circle.
Two friends held each end of the strings, while someone spun the circle tightly. Then we let go and watched our pictures spin.
Kayley's cat was eating the cat food from the bowl.
Deven's frog just missed the fly so it's still hungry!
Rafael's scored at the bottom of the net on the grass.
Nye'Jah's pig was playing in the middle of the mud.
Isabella's fish was swimming in the bowl between the seaweed.
When you spin
the disk slowly,
you see two separate
But when the disk
spins very quickly,
creates one image.
