Twelfth grade Science topics covered

Earth's history and climate

  • Construct an explanation based on evidence for how the distribution of fossils and rocks supports plate tectonics
  • Evaluate evidence of the past and current movements of continental and oceanic crust
  • Develop a model to illustrate the role of the ocean, atmosphere, and ecosystems in the cycling of carbon

Environmental science

  • Evaluate evidence of the factors that have caused the rise in global temperatures
  • Create a computational simulation to illustrate the relationships among management of natural resources
  • Analyze geoscience data and the results from global climate models to make an evidence-based forecast of the current rate of global or regional climate change
  • Evaluate the evidence of the effects of past global climate changes

Scientific inquiry and research

  • Ask questions that arise from careful observation of phenomena
  • Construct explanations and design solutions based on scientific knowledge
  • Plan and conduct investigations collaboratively to produce data
  • Analyze and interpret data using computational thinking
