17.B Apply ideas about ways of growing food to design a better way to use the land to minimize human impact on orangutan populations.

• Using a variety of different ways to grow food can maintain or increase orangutan populations and people's income.
• People can reasonably set aside a portion of their land to support orangutan populations without reducing their income.
• Neighboring farms can coordinate their approaches to increase space for orangutans.
• Rainforest corridors connecting intact areas of forest increase orangutan populations.

Students should identify 2 features of a diversified palm farm that support people and biodiversity, along with how each of these features works. Example features include:

Feature

How it works

Many crops

• Protects people in case of a disruption and can give them steady income.
• Creates multiple layers, which act more like a forest for animals, insects, and birds.

Forest set aside or corridor

• People can get the same amount of crop with less land.
• Protecting part of the land for forest creates corridors for animals to travel through.

Look ahead at the rubrics provided in Lesson 18. Rubric Option 1: Redesign the Land or Rubric Option 2: Redesign the Land are offered as ways to score group and individual design work and provide feedback. If students struggle to generate ideas for the design of the land, consider projecting an existing solution and evaluating the trade-offs of the solution. The code for one possible design solution is located in the Design Solution Slide Deck, slide 1, notes section. Copy this code into the simulation and run the simulation. Prompt students to identify design features in the design (e.g., corridor, areas of customary forest grouped together, using land already cleared of forest to plant oil palm). Then prompt students to consider how and why the different features work. Once students have had the opportunity to see and think about a potential design, have students work on their own and in their groups to create a new design.

Complete the teamwork self-assessment. In addition to writing an explanation, students should complete the Teamwork Self-Assessment. Use this as an opportunity to help students reflect on their own work and to provide feedback on their teamwork.
