Mike Myers is a teacher at Chauncey Rose High School in Terre Haute, Indiana.  Last year, he taught his students about the world’s rain forests.  They learned that rain forests are important because the plants and animals of the rain forest give us food, wood, and medicine.

Destruction of the world’s rain forests is a serious problem.  Unluckily, rain forests are disappearing at a rate of 80 acres per minute!  As part of a class project, Myers’ students bought three acres of rain forest in Central America.  They paid $25 per acre.  The students hope that the land they bought will be protected and not destroyed. The students became so interested in rain forests that they decided to get a closer look at a real rain forest.

So last June, Myers and four of his students took a boat ride down a river.  They saw alligators and crocodiles.  In the middle of the week, a guide took Myers and his students into the rain forest.  “The monkeys were not happy that we were in their forest.  They broke small branches off the trees and threw them at e us,” one of the students said, “It was a great learning experience for all of us,” said Myers.

Each student chose something specific about Costa Rica to study involving the plants, animals, food, and culture.  During the last few days the group had time to do fun activities.  They went whitewater rafting and horseback riding, and visited Costa Rica’s active volcano.

Myers hopes to make the trip every year with a different group of kids.
