Invasive species impacts and spread are the focus of this Grade 6 Science resource, giving students a clear way to explore how non-native organisms become established and affect biodiversity in ecosystems. The resource examines ecological relationships and asks students to connect invasive species with changes to native populations, food webs, and habitat conditions.

What Students Explore

Students investigate how invasive species are introduced and become established in new ecosystems. They describe how competition, predation, and habitat changes can affect native species and alter food webs. The resource also introduces evidence-based indicators for monitoring invasive species and their effects, while asking students to apply ecological ideas to predict what may happen when a non-native organism enters a habitat.

These concepts support classroom discussion around biodiversity, ecosystem interactions, invasive species spread, native species, and ecological change. Students work with multiple-choice questions, true/false statements, short-answer responses, a reading passage, matching, a cloze passage, an essay, and a “Did You Know?” component. This range gives teachers opportunities to check factual knowledge, written reasoning, reading, and application of ecological concepts.

What You Receive

• ✅ Student worksheet focused on invasive species impacts and spread
• ✅ Separate PDF answer key for checking student responses
• ✅ Student Notes & Lesson Summary supplement for supporting instruction and review
• ✅ Separate Teacher Guide with Learning Objectives, Teaching Tips, Discussion Questions, and Common Mistakes

Classroom Use

Use this Grade 6 biodiversity worksheet as guided practice after instruction, independent classwork, review, or an assessment opportunity. The reading and written-response components can support students as they explain ecological relationships, while the application-focused questions provide opportunities to predict outcomes when invasive organisms enter a habitat.

The included student notes provide an additional reference for reinforcing the lesson, while the teacher guide helps organize instruction with objectives, discussion prompts, practical teaching tips, and attention to common mistakes. The separate answer key makes response checking more efficient.

Why It Fits a Biodiversity Unit

This resource keeps the focus on specific ecological cause-and-effect relationships rather than treating invasive species as an isolated vocabulary topic. Students connect introduction and establishment with competition, predation, habitat changes, food-web effects, ecosystem monitoring, and biodiversity. The Ontario framework context also gives teachers a resource designed for Grade 6 Science instruction within that curriculum setting.
