This resource turns waste reduction and circular into a complete, ready to use review for Grade 9-12 earth science, covering the same NGSS standard from three different angles.

The set includes questions like "What is a key challenge in recycling infrastructure?", "What is the main objective of composting?", and "How does life-cycle assessment (LCA) support sustainability?"

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

• No prep cover lesson for a substitute teacher
• Review station before a lab or field activity
• Self checking practice, since every answer key includes explanations
• Bell ringers and warm ups during the unit

Suitable for Grade 9-12 earth science classes, and for review at any point in the school year. This set is aligned to NGSS standard HS-ESS3-6.
