The Lost in the Amazon curricular unit is a series of minds-on and hands-on engineering activities based in the Amazon rainforest in Brazil. Motivated by an adventurous theme, students discover, learn and apply a variety of skills. Students work in teams to overcome various obstacles in their quest to reach the nearest city after their plane crashes deep in the Amazon. The ideal implementation of this curricular unit is for students to complete the activities in sequence. However, the activities are self-contained and can be implemented separately.
