Give your biology students a focused look at biological component changes with ninety questions built for real classroom use, whether you are starting a new unit or reviewing before a test.
Among the ninety questions, students will see prompts such as "What is a possible outcome of pollution in an ecosystem?", "What structural change can occur after a forest fire?", and "How can a disease outbreak in a species impact its ecosystem?"
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 standards aligned biology unit. The unit also covers Resources and Population Size, Competition for Resources, Types of Species Interactions, Interactions Across Ecosystems, Matter Cycling in Ecosystems, and Energy Flow in Food Webs, all in the same three worksheet format, so your classroom routine stays familiar while the topic changes.
Suitable for Grade 7 biology classes, and for review at any point in the school year. This set is aligned to NGSS standard MS-LS2-4.
