Quick summary: Students will review trophic levels and interactions between species. They will create a habitat display proposal for a newly discovered subspecies, including information about its interactions, a food chain and the consequences of a human impact on the ecosystem. They will then provide feedback to their peers about their proposals.
- Students understand how to identify and describe the position of an organism in an ecosystem
- Students understand that a food chain shows how organisms interact in an ecosystem
- Students understand how a human-caused event can impact an ecosystem.
21st century skills:
Australian Curriculum Mapping
Year 7 Science
- Interactions between organisms, including the effects of human activities can be represented by food chains and food webs (ACSSU112)
- Communicate ideas, findings and evidence based solutions to problems using scientific language, and representations, using digital technologies as appropriate (ACSIS133)
Syllabus outcomes: SC4-5WS, SC4-14LW.
Cross-curriculum priority: Sustainability OI.2.
Relevant parts of Year 7 achievement standards: They predict the effect of human and environmental changes on interactions between organisms and classify and organise diverse organisms based on observable differences. They communicate their ideas, methods and findings using scientific language and appropriate representations.
Topic: STEM, Sustainability, Biodiversity.
