Stick insects use camouflage to hide from predators. These long, leggy insects look exactly like the twigs of the trees that are their homes. When in danger, stick bugs stand perfectly still, blending in with the bark around them. To drive this lesson home, help your students or children create stick insect models. Hide them among the branches of small trees and see if the kids can find them afterward.
Select a 6-inch twig for each stick bug. The more bumps and irregularities in the twig, the better.
Cut three 12-inch wires for each stick bug. Wrap the center of each wire around the twig, spacing the wires about 1.5 inches apart.
Bend and twist the wires into legs. You may give the legs sharp corners and texture, but they must have definable knees and ankles where they bend.
Cut a 6-inch wire and wrap it around the tip of the twig for antennas. Glue plastic eyes to either side of the twig tip with white school glue. Let it dry for two hours.
