This Grade 7 science course introduces cell reproduction, sexual and asexual reproduction, ecosystems, ecological relationships, energy flow, population changes, and ecosystem protection through models, research, presentations, and collaborative projects.

Syllabus

  • Analyze the stages of the cell cycle and cell reproduction by designing and presenting a model or simulation that addresses an open-ended question about how cells multiply in real-world contexts.
  • Compare and contrast types of sexual and asexual reproduction by collaborating on a research project that investigates reproduction strategies in diverse organisms and presents findings to peers for feedback.
  • Illustrate the process of fertilization by developing a visual or digital representation that responds to a challenge question about genetic variation and shares results with classmates for critique.
  • Differentiate biotic and abiotic components of ecosystems by creating an interdisciplinary project that explores their interactions in a local or global ecosystem and presents conclusions to the class.
  • Evaluate different relationships within ecosystems by investigating real-world case studies and constructing a collaborative presentation that addresses the impact of these relationships on ecosystem stability.
  • Model the transformation of energy through feeding relationships by developing and sharing a food web or energy flow diagram that answers an open-ended driving question about ecosystem dynamics.
  • Propose and justify collective actions for ecosystem protection by collaborating on a project-based campaign or solution that addresses a current environmental issue and seeks peer and community feedback.
  • Describe the stages of the cell cycle and explain how cells reproduce through mitosis and meiosis.
  • Identify and differentiate the types of asexual reproduction (e.g., binary fission, budding, fragmentation, regeneration, etc.).
  • Enumerate and explain the types of sexual reproduction and describe the process of fertilization.
  • Classify the abiotic and biotic components of an ecosystem.
  • Describe the basic components and identify the major types of ecosystems (e.g., terrestrial, aquatic).
  • Explain the different ecological relationships such as mutualism, commensalism, parasitism, predation, and competition.
  • Illustrate how energy is transferred through food chains and food webs in an ecosystem.
  • Analyze how population changes affect ecological balance and describe the role of environmental factors.
  • Justify the importance of collective action in protecting and preserving ecosystems.
