Katrina648's art on ArtsoniaSecond graders learned about rain forest tree dart frogs. We learned that the Amazon rain forest covers much of South America and contains millions of plant and animal species. The poison dart frog has very brilliant colors and warns predators to stay away. The sweat from one frog is enough to coat 50 darts for native people to hunt with...wow! For our lesson, we traced a frog template and cut it out.
