Earth science ideas click fastest with real practice. This set gives your Grade 9-12 class ninety questions on biogeochemical cycles, aligned to the same NGSS performance expectation.
Among the ninety questions, students will see prompts such as "Which process describes the conversion of nitrates back to nitrogen gas?", "How does human activity contribute to the sulfur cycle?", and "Which of the following processes is NOT part of the carbon cycle?"
Because the three worksheets share the same content in three different formats, you can spread them across the week: one for diagnosis, one for practice, and one for assessment, without repeating a single question.
This set is part of a NGSS aligned earth science unit. The unit also covers Earth's Spheres Atmosphere, Rock Cycle and Material, Hydrologic Cycle and Earth, Mineral Resources and Human, Soil Formation and Profiles, and Erosion and Deposition, all in the same three worksheet format, so your classroom routine stays familiar while the topic changes.
Suitable for Grade 9-12 earth science classes, and for review at any point in the school year. This set is aligned to NGSS standard HS-ESS2-3.
