Unit 3 — Natural Resources & Human Impacts on Earth

• Analysis of data sets on natural hazards and their frequency to develop predictions about future events.
• Design process activities where students define criteria and constraints for environmental monitoring or mitigation solutions.
• Discussion and argument-building exercises using evidence about human population growth and resource consumption impacts.
• Illustration and mapping activities identifying the global distribution of natural resources.
• Evaluation of competing design solutions using systematic comparison of how well they meet specified criteria.

Students develop a design solution for monitoring and minimizing human impact on the environment, incorporating scientific principles and engineering design processes. The solution must address criteria and constraints, integrate evidence about natural resource distribution and human impacts, and demonstrate understanding of trade-offs between environmental and economic needs.

A short-answer task requiring students to explain how one Earth resource (mineral, energy, or water) became unevenly distributed due to geoscience processes, interpret a data set on natural hazards to make one prediction, and sketch one method for monitoring or reducing human environmental impact. This assesses all three learning objectives across the unit.

Students may demonstrate understanding through oral explanation of resource distribution or hazard data with teacher guidance, supported by diagrams or models. A simplified design task focused on one component of environmental monitoring or mitigation, with sentence frames and partially completed graphic organizers, may replace the full design solution.

Students with IEPs may benefit from scaffolded support when processing complex data sets related to natural hazards, resource distribution, and climate change — such as graphic organizers, partially completed charts, or annotated visuals that reduce cognitive load while preserving access to grade-level content. For argument-building and design tasks, breaking multi-step processes into sequenced, numbered stages with clear checkpoints helps students track their progress and demonstrate mastery incrementally. Output flexibility is important throughout this unit: students should have options to present their environmental design solutions through oral explanation, labeled diagrams, or recorded responses rather than relying solely on extended written work. Teachers should check in frequently during inquiry and design activities to provide feedback and redirect as needed before students reach the summative task.

Students with 504 plans should be afforded extended time on data analysis tasks and the summative design project, given the volume of evidence-based reasoning required across this unit. Preferential seating and a reduced-distraction environment are especially relevant during discussion and argument-building activities, where sustained focus on peer contributions and data interpretation is essential. Providing printed copies of maps, data sets, and directions — rather than requiring students to copy or navigate multiple digital sources simultaneously — supports consistent access to the unit's content without creating barriers to participation.

Multilingual learners will benefit from a visual-rich approach throughout this unit, including labeled maps of global resource distribution, picture-supported vocabulary references for key terms such as 'geoscience processes,' 'biodiversity,' 'mitigation,' and 'per-capita consumption,' and short video segments with captions that build background knowledge about human environmental impact. Directions for design activities and data tasks should be simplified and presented step-by-step, with teachers checking comprehension by asking students to restate the task in their own words before beginning. Where possible, students should be encouraged to process ideas and draft responses in their home language first before translating into English, supporting deeper engagement with the unit's scientific concepts.

Students who need additional support should be connected to the unit's concepts through familiar, local examples of resource use, environmental change, or natural hazard events before moving to global or abstract contexts. Data analysis tasks can be scaffolded by reducing the number of variables students are asked to examine at one time, allowing them to build confidence and fluency with scientific reasoning before tackling more complex comparisons. For the design solution, providing a structured framework with guiding questions — such as prompts about who is affected, what the problem is, and what trade-offs exist — gives students a manageable entry point into the engineering design process while still engaging with meaningful, grade-level thinking.

Gifted students should be challenged to move beyond description and into critical analysis, examining competing scientific and policy perspectives on resource management, climate intervention strategies, or the ethics of environmental trade-offs between economic development and ecological preservation. For the summative design task, these students can be encouraged to consult real-world case studies, scientific reports, or data from environmental organizations to add sophistication and originality to their proposed solutions. Extension opportunities might also invite students to explore systems thinking — tracing how a change in one Earth system (such as freshwater availability) creates cascading effects across biosphere, atmosphere, and human society — pushing toward the kind of interdisciplinary, complex analysis that characterizes advanced scientific inquiry.
