This resource turns explain your model into a complete, ready to use review for Grade 6-8 chemistry, covering the same NGSS standard from three different angles.

Students will answer questions such as "Which of the following best describes the concept of overfitting?", "What is a primary benefit of using visualizations when explaining your model?", and "Why is it important to provide clarity in your modeling choices?"

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

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

This set is part of a complete NGSS aligned chemistry unit. The unit also covers Water Molecule Drawing, Carbon Dioxide Model, Ammonia 3D Sketch, Methanol Structure, Diamond Lattice Illustration, and Sodium Chloride Pattern, all in the same three worksheet format, so your classroom routine stays familiar while the topic changes.

Suitable for Grade 6-8 chemistry classes, and for NGSS aligned review at any point in the school year. This set is aligned to NGSS standard MS-PS1-1.
