Grades K and up
If you had to name the shape of a broccoli head, what would you say? What about the shape of a river from an aerial point-of-view? And what about the human lungs? In her photo essay Mysterious Patterns: Finding Fractals in Nature, Sarah C. Campbell provides students with the vocabulary needed to answer those questions. A fractal, she explains, starts with one shape and “changes in the same way over, and over, and over again.” Teaming up with husband and fellow photographer Richard P. Campbell, she provides lots of visual examples of what a fractal is and what it isn’t. Close-up photos of Queen Anne’s lace, lightning, and fern leaves demonstrate the concept of a fractal, with some photos zooming in on the tinier parts of the object to illustrate how their structure mimics the larger one. Uncomplicated explanations also make it clear how the designs of a pineapple skin and a swallowtail caterpillar’s stripes, though repeated across their surfaces, are not fractals. Woven throughout the text is an introduction to Benoit Mandelbrot, the perceptive mathematician who coined the term, and a set of directions for making your own fractal nicely rounds out the discussion. An afterword by Mandelbrot’s colleague at Yale provides more information about him as well as examples of manmade fractals that are integral to modern society. A picture book made to fascinate young minds with math and science, Mysterious Patterns is a valuable addition to classrooms everywhere.
Teaching Ideas and Invitations
Fractals Gallery. Invite students to search their environments for the fractals that can be found around them. Have them bring in examples of those fractals, or ask them to take photos of the objects either with a tablet or a smartphone. Encourage them to keep their eyes open for fractals every time they step outside, and remind them that examples are everywhere: a tree on the way home, a broccoli floret at the grocery store, maybe even a design on a t-shirt. Set up a bulletin board, a bookshelf, or a corner of the classroom as a gallery to showcase student’s examples of fractals.
The Influence of Benoit Mandelbrot. Michael Frame’s afterword describes Mandelbrot’s upbringing and continued contributions to the worlds of math and science. Have students research more about Mandelbrot’s life. Then, encourage students to inquire more about the inventions that are based on the concept of fractals: cellphone antennas, air conditioners, Cohen’s radar invisibility cloak, etc.
Patterns in Nature. Fractals are not the only kinds of patterns found in nature. Campbell points out the stripes on a swallowtail caterpillar as an example of another kind of pattern. Share some of the books listed below in Further Explorations that examine others kinds of patterns in nature. Then take students on a nature walk around the school, at a nearby park, or anywhere else where they can see some natural plants, animals, and formations. Assign different patterns to groups of students, and have them search for examples of those patterns in nature. Arm them with tablets, smartphones, or just a pen and pad of paper to sketch or photograph the examples they see. Have them share their findings in class and perhaps publish them in a class-created book.
Create Your Own Fractal. Study the directions at the end of the book that explain how to create your own fractal. Then show students more examples of fractals that have been drawn or constructed by students (see some of the websites listed below in Further Explorations). Provide students with a wide array of art supplies and invite them to draw, paint, or sculpt their own fractals. Make sure they adhere to the rule that a fractal repeats the same structural pattern over and over again.
Photographing Natural Objects. The photographs in Mysterious Patterns provide new and interesting ways to view the things we see in nature every day. Have students study the photography of natural objects by gathering a number of photo essays that deal with nature. Ask a school or local librarian for help. Many examples can be found on this blog by typing “photo essay” into the search box. How do the photographers present the objects in ways different from how we encounter them in nature? What differences do you notice when photographing animate and inanimate subjects, live creatures and still objects? Invite students to practice photographing various objects in nature and display them in a classroom or school gallery. You might even ask them to focus on a specific topic or concept to unite their photographs and then construct their own photo essay picture book with them.
