This resource turns the role of keystone species into a complete, ready to use review for Grade 6-8 biology, covering the same NGSS standard from three different angles.
Students will answer questions such as "In what way do sea otters benefit kelp forests?", "What effect do keystone species have on biodiversity?", and "What is a potential consequence of removing sea otters from their environment?"
All three worksheets cover the same topic in different question styles. That means you can use one as a pretest, another for practice or homework, and the third as a follow up quiz, without students ever seeing the same question twice.
This set is part of a complete NGSS aligned biology unit. The unit also covers What Are Ecosystem Services, Biodiversity and Ecosystem Services, Human Impact on Biodiversity, Natural Hazards and Ecosystems, Designing Solutions Urban Greening, and Agriculture and Biodiversity, all in the same three worksheet format, so your classroom routine stays familiar while the topic changes.
Suitable for Grade 6-8 biology classes, and for NGSS aligned review at any point in the school year. This set is aligned to NGSS standard MS-LS2-5.
