This resource turns harmful mutations into a complete, ready to use review for Grade 7 biology, covering the same idea from three different angles.

Among the ninety questions, students will see prompts such as "What is one potential benefit of studying harmful mutations?", "How might harmful mutations influence natural selection?", and "What is one way scientists study harmful mutations?"

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.

• Homework or review before a quiz
• Bell ringers and warm ups during the unit
