This resource turns mass extinctions into a complete, ready to use review for Grade 6-8 earth science, covering the same NGSS standard from three different angles.

Sample questions include "What characterized the biodiversity changes after the Ordovician extinction?", "What was a potential cause of the Triassic-Jurassic extinction?", and "Which event led to the extinction of 90% of marine species?"

What's Inside?

• 30 Multiple Choice questions as a separate print ready PDF worksheet
• 30 True or False questions as a separate print ready PDF worksheet
• 30 Short Answer questions as a separate print ready PDF worksheet
• Includes Answer Key with Explanations for all 90 questions
• 6 print ready PDF files, 26 pages in total

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.

Ways to Use This Resource

• Homework or review before a test
• Bell ringers and warm ups during the unit
• First look diagnostic to plan your unit
• No prep cover lesson for a substitute teacher
• Self checking practice, since every answer key includes explanations

This set is part of a NGSS aligned earth science unit. The unit also covers Introduction to Geologic Time, Layers of Rock, Fossils and the Rock Record, Relative and Absolute Dating, Geological Timeline Creation, and Analyzing Rock Sequences, all in the same three worksheet format, so your classroom routine stays familiar while the topic changes.

Suitable for Grade 6-8 earth science classes, and for review at any point in the school year. This set is aligned to NGSS standard MS-ESS1-4.
