OpenSciEd Biology + Earth & Space Unit 4: Natural Selection & Evolution of Populations Student Workbook

OpenSciEd High School addresses all high 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. 

B.4 Natural Selection & Evolution of Populations: How does urbanization affect nonhuman populations, and how can we minimize harmful effects?

This unit on natural selection and evolution of populations focuses on the phenomenon of increasing urbanization around the world and the impact of that change on nonhuman populations. Students investigate case studies that investigate fragmentation, poison, and proximity to humans as selection pressures that affect the relative fitness of individuals with particular anatomical, physiological, and behavioral traits in a population. Through investigations with complex data sets, they figure out how genetic diversity in a population allows populations to adapt to changes encountered in urban environments.

Students apply their knowledge of evolution by natural selection to explain why small, fragmented populations can be more vulnerable to change than large populations. They investigate the effectiveness of various human-engineered designs in reducing the effects of fragmentation on nonhuman populations. Students apply their knowledge to evaluate proposed design solutions for urban growth in Buckeye, Arizona, one of the fastest-growing cities in the United States. They discuss criteria to balance protecting biodiversity with human needs in the area.

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.

The Student Edition, Teacher Edition and material kits are sold separately.
