This document outlines a project-based learning unit on rainforests for elementary school students. The multi-week project teaches students about the different layers of the rainforest and has them create informative posters. Students then present their posters and collaborate on a slideshow presentation for parents. To reinforce conservation, the class also raises money for the Rainforest Alliance by creating and selling snack packages made from rainforest plants. The project aims to develop students' collaboration, communication, critical thinking, and problem-solving skills.
