Try This! 28 Camouflage a potato. Use a small potato, stick pins or glue, and a variety of materials, such as dried beans, seeds, feathers, leaves, and straw. ” It might be outside in a tree or in the grass or indoors on a rug or on your bed. Decorate your potato with materials that will help it blend in to its environment. For example, if you want it to blend in with your blue bedspread, then you might cover it with blue feathers, beads, or buttons. Share your camouflaged creature with your class, and show or describe the environment it’s adapted to.

They’ve cleared rain forests to build roads and cities. They fish the oceans, hunt animals on land, and pollute the air and water. Humans change and destroy habitats every day. Human actions have made survival difficult or impossible for many species. Some plants and animals have not been able to adapt to their rapidly changing or disappearing environments. Some have become endangered, and others have become extinct. And while extinction is part of Darwin’s natural selection process, the recent increase in the extinction of species is believed to be due to human behavior, not nature.
