Biology ideas click fastest with real practice. This set gives your Grade 9-12 class ninety questions on molecular evidence, aligned to the same NGSS performance expectation.

Sample questions include "What does the study of proteins across species reveal?", "Why are DNA sequences more reliable than morphological traits in determining relationships?", and "How do pseudogenes contribute to evolutionary studies?"

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

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.

Ways to Use This Resource

• Review before a lab or class discussion
• Homework or review before a quiz
• No prep cover lesson for a substitute teacher
• Bell ringers and warm ups during the unit
• Self checking stations, since every answer key includes explanations

This set is part of a complete NGSS aligned biology unit.
