Overview

Grade 6 ecosystems NGSS Science worksheets build student understanding of how organisms interact, how resources shape populations, and how energy moves through food webs. This lesson bundle provides 5 focused worksheets to support instruction aligned to NGSS Grade 6 Science.

What’s Included

• ✅ Species Interactions Across Ecosystems Worksheet | NGSS Grade 6 Science – Students connect organism relationships (such as competition and predation) to changes in ecosystem stability.
• ✅ Resource Limits and Carrying Capacity Worksheet | NGSS Grade 6 Science – Learners analyze how limited resources influence population size over time.
• ✅ Science Worksheet Population Change | NGSS Grade 6 Science Assessment – Students interpret population change ideas using evidence and complete an assessment-style response.
• ✅ Energy Flow in Food Webs Worksheet | NGSS Grade 6 Science Assessment – Students trace energy pathways and support claims about trophic levels using diagrams.
• ✅ Biodiversity Solutions Keeping Ecosystems Working Worksheet NGSS Grade 6 Science – Learners explain how biodiversity and human choices can maintain ecosystem function.

Skills & Standards

Built for NGSS instruction, these worksheets naturally support crosscutting concepts such as Systems and System Models and Cause and Effect. Students apply disciplinary core ideas from LS2 (including how ecosystems function and how energy and matter flow through living systems). Each activity emphasizes modeling with ecosystem and food web representations, analytical reasoning when interpreting population and energy patterns, and evidence-based explanations grounded in worksheet prompts and representations. The tasks encourage students to make claims, identify relevant evidence, and reason from observations to ecosystem outcomes in line with NGSS expectations.

Perfect For

• Teachers seeking structured instruction
• Sub plans
• Homework or review
• Intervention or centers
• Assessment preparation

How to Use

Use this lesson bundle across 5 class periods (or spread into 2–3 longer blocks) so students can move from ecosystem interactions to resource limits, then toward population change and energy flow, and finally apply the ideas to biodiversity solutions. Suggested pacing: Day 1 for organism interactions, Day 2 for resource limits and carrying capacity, Day 3 as an assessment practice with population change, Day 4 for energy flow in food webs, and Day 5 for applying learning to biodiversity solutions. For differentiation, allow students to complete the modeling portions first (food web/relationship diagrams), then return to written explanations; for centers, place one worksheet per station and rotate so students discuss evidence before final responses.
