Biology ideas click fastest with real practice. This set gives your Grade 9-12 class ninety questions on types of natural selection, aligned to the same NGSS performance expectation.
Among the ninety questions, students will see prompts such as "What type of selection favors intermediate phenotypes in a population?", "Which selection type is often depicted with a graph showing two peaks?", and "What is a potential outcome of disruptive selection?"
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 complete NGSS aligned biology unit. The unit also covers Principles of Natural Selection, Selective Pressures, Fitness and Adaptation, Evolution by Natural Selection, Genetic Variation and Evolution, and Artificial and Natural Selection, all in the same three worksheet format, so your classroom routine stays familiar while the topic changes.
Suitable for Grade 9-12 biology classes, and for NGSS aligned review at any point in the school year. This set is aligned to NGSS standard HS-LS4-2.
