OpenSciEd Unit 7.5: Ecosystem Dynamics Student Workbook

OpenSciEd Middle School science program addresses all middle school NGSS standards. This comprehensive science curriculum empowers students to question, design, investigate, and solve the world around them. 

• Phenomenon Based - Centered around exploring phenomena or solving problems
• Driven by Student Questions - Storyline based on students’ questions and ideas 
• Grounded in Evidence - Incremental building and revision of ideas based on evidence 
• Collaborative - class and teacher figure out ideas together
• Equitable - Builds a classroom culture that values ideas and learning of all

The OpenSciEd model uses a storyline approach, introducing phenomena that anchors storylines developing disciplinary core ideas, concepts, and science/engineering practices. Students are encouraged to dive deep into key points and solve problems through five activities. Students kick off a unit of study, investigate questions, piece together the puzzle in investigations, and problematize the next set of questions to investigate. 

Unit 7.5: How does changing an ecosystem affect what lives there?
This unit on ecosystem dynamics and biodiversity begins with students reading headlines that claim that the future of orangutans is in peril and that the purchasing of chocolate may be the cause. Students then examine the ingredients in popular chocolate candies and learn that one of these ingredients--palm oil--is grown on farms near the rainforest where orangutans live. This prompts students to develop initial models to explain how buying candy could impact orangutans.

Students spend the first lesson set better understanding the complexity of the problem, which cannot be solved with simple solutions. They will figure out that palm oil is derived from the oil palm trees that grow near the equator, and that these trees are both land-efficient and provide stable income for farmers, factors that make finding a solution to the palm oil problem more challenging. Students will establish the need for a better design for oil palm farms, which will support both orangutans and farmers. The final set of lessons engage students in investigations of alternative approaches to growing food compared to large-scale monocrop farms. Students work to design an oil palm farm that simultaneously supports orangutan populations and the income of farmers and community members.

Perfectly aligned with each unit, the consumable student workbook provides students with a dedicated space to write through their ideas and thoughts with every exercise and activity helping to reinforce important themes and concepts.
