My third graders are going to explore the primary & secondary colors, complementary colors, patterns, rotational symmetry, while learning the geometry of a circle in these color wheel paintings. Then they will be compared to op art as students rotate and digitally fall into them using Do Ink drawing and animation app on the iPad.
The animation begins by drawing to objects in the DoInk Animation App.
Both objects need to be a complementary color pairs (red/green), (purple/yellow), (orange/blue)
1. The first object is a circle with lines that converge at the center. I used a spiral, but the lines could also radiate out/in with straight, jagged, curving, bumpy, (whatever) lines.
2. The second object is a figure drawing in the style of Keith Haring. This figure is a solid color with a shape pattern in the complement. I used circles but you can use squares, diamonds, hearts, ovals, flowers, leaves, (whatever) shapes.
The two objects are then layered in the composition mode of the DoInk app. I stretched them both out to 6 seconds and set opposite direction rotations on each.
Then I altered the size of the figure so that it began full size and ended almost so tiny that it disappeared.
The lesson is designed to help students see that complementary colors are extra vibrant in your eyes. The rotation of the lines as they converge into the center create an optical illusion that adds depth to the image. The shrinking of the figure creates the illusion of depth as if he/she is falling. Below is video:
Variation of the idea:
This was my first attempt at this animation idea. In this animation I used the Kaleido Free app to draw lines converging to the center. The app allows you to save your drawing as a movie. To layer the figure and the movie I used the Green Screen App by DoInk.
Hypno Bot (another variation)
Pretty much anything can fall, rotate, and shrink away. Here is a 5th grader's robot falling over two layers of images. One layer is a semi-transparent rotating spiral and the other is a geometric patterned design.
The Quick Version:
Since you can animate photos using the DoInk Animation App, I think this variation on the idea may be the fastest one. Students will pose as if they are falling (in front of green screen). Then they will draw an optical illusion circle (like a spiral design). This will be photographed also.
This lesson was definitely rewarding for my students though it did require doing the same drawing twice as they spun the paper and repeated their ideas. They painted with tempera paints and metallics then outlined in black and metallic markers. When they were finished I photographed and printed their paintings small enough to look like a real playing card. Though the lesson teaches symmetry, it is really a test of observational drawing skills. These 5th graders really wowed me with their skill & attention to detail.
I printed out symbols for students to apply to their cards after the art was painted, trimmed, and glued to a piece of tag board.
I put the whole lesson with resources and print outs together in one ppt that you can download from TpT here.
The DoInk animation app allows for many many different techniques that can reinforce rotational symmetry. Here is an idea for creating an animated rotationally symmetrical playing card. The animation is created over (blank) photo downloaded from photofunia.
Our Lego Wall was made possible because of so many people working together. It was a collaborative project in every way. Thank you!
Taking a Turn
This video explains how to make a rotationally symmetrical with legos collaboratively using a method that is a simple as taking a turn.
I wrote up this lesson for School Arts Magazine published Nov. 2013. View it here.
Dryden's art program won an ABC/25 grant for materials for a Lego wall. This year we are using our supplies to collaboratively make radially symmetrical designs on our square base plates. We've found that this is not as easy as it sounds. One misplaced block can throw off everything. So, I structured the lesson into a game that ensures everyone takes turns one piece at a time. The 3/4 cardboard shields keep the eyes focused on the design as you rotate the baseplate for each turn. The kids LOVE this activity and seem to want to play/create endlessly. See our finished Lego designs online here or in the display case at school.
