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.
Lesson 1: How could buying candy affect orangutan populations in the wild?
Lesson 2: Can we replace palm oil with something else?
Lesson 3: Can we grow oil palm trees somewhere else so that we’re not cutting down tropical rainforests?
Lesson 4: Why do people cut down tropical rainforests when they know it is harmful to the animals that live there?
Lesson 5: How have changes in our community affected what lives here?
Lesson 6: If palm oil is not going away, how can we design palm farms to support orangutans and farmers?
Lesson 7: How many orangutans typically live in the tropical rainforest?
Lesson 8: Why do orangutans need so much forest space?
Lesson 9: Would planting more rainforest fruit trees help the orangutan population increase? Lesson 10: How do changes in the amount of resources affect populations?
Lesson 11: How does planting oil palm affect other populations?
Lesson 12: What would happen if orangutans go extinct?
Lesson 13: How does an ecosystem change when the plants change?
Lesson 14: Are there ways people can grow food without harming the tropical rainforest?
Lesson 15: How can people benefit from growing food in ways that support plants and animals in the natural ecosystem?
Lesson 16: What approach to growing food works for everyone and why?
Lesson 17: How can we redesign the way land is used in Indonesia to support orangutans and people at the same time?
Lesson 18: How do our designs work for orangutans and people in Indonesia?
Lesson 19: How can we inform others in our community about the palm oil problem and convince them to take action?
Lesson 20: What should we do to take care of our local land, plants, and animals?

OpenSciEd® was launched to improve the supply of and address the demand for high-quality, open-source, full course science instructional materials. The goals of OpenSciEd are to ensure any science teacher, anywhere, can access and download freely available, high quality, locally adaptable materials. Though the goal of providing full course materials is still a couple of years away, OpenSciEd is releasing six-week units of instruction as they are completed and externally evaluated as quality by Achieve’s Science Peer Review Panel. OpenSciEd classroom materials are an open education resource and therefore free to download, copy, use, and/or modify. You can download the instructional materials free of charge at Access Materials page on the OpenSciEd website. In an effort to lower barriers for all educators to use OpenSciEd, Kendall Hunt and OpenSciEd have partnered to sell high quality printed books, professional learning and lab kits.
