Plan and conduct an investigation to provide evidence that feedback mechanisms maintain homeostasis.
Students will use a model to illustrate how photosynthesis transforms light energy into stored chemical energy.
Use a model to illustrate how photosynthesis transforms light energy into stored chemical energy.
Students will construct and revise an explanation based on evidence for how carbon, hydrogen, and oxygen from sugar molecules may combine with other elements to form amino acids and/or other large carbon-based molecules.
Students will use a model to illustrate that cellular respiration is a chemical process whereby the bonds of food molecules and oxygen molecules are broken and the bonds in new compounds are formed resulting in a net transfer of energy.
Students will construct and revise an explanation based on evidence for the cycling of matter and flow of energy in aerobic and anaerobic conditions.
Students will use mathematical representations to support claims for the cycling of matter and flow of energy among organisms in an ecosystem.
Students will develop a model to illustrate the role of photosynthesis and cellular respiration in the cycling of carbon among the biosphere, atmosphere, hydrosphere, and geosphere.
Students will use mathematical and/or computational representations to support explanations of factors that affect carrying capacity of ecosystems at different scales.
Students will use mathematical representations to support and revise explanations based on evidence about factors affecting biodiversity and populations in ecosystems of different scales.
Students will evaluate the claims, evidence, and reasoning that the complex interactions in ecosystems maintain relatively consistent numbers and types of organisms in stable conditions, but changing conditions may result in a new ecosystem.
Students will design, evaluate, and refine a solution for reducing the impacts of human activities on the environment and biodiversity.*
Students will evaluate the evidence for the role of group behavior on individual and species’ chances to survive and reproduce.
Students will create or revise a simulation to test a solution to mitigate adverse impacts of human activity on biodiversity.*
Students will use a model to illustrate the role of cellular division (mitosis) and differentiation in producing and maintaining complex organisms.
Students will ask questions to clarify relationships about the role of DNA and chromosomes in coding the instructions for characteristic traits passed from parents to offspring.
Students will make and defend a claim based on evidence that inheritable genetic variations may result from: (1) new genetic combinations through meiosis, (2) viable errors occurring during replication, and/or (3) mutations caused by environmental factors.
Students will apply concepts of statistics and probability to explain the variation and distribution of expressed traits in a population.
Students will communicate scientific information that common ancestry and biological evolution are supported by multiple lines of empirical evidence.
Students will construct an explanation based on evidence that the process of evolution primarily results from four factors: (1) the potential for a species to increase in number, (2) the heritable genetic variation of individuals in a species due to mutation and sexual reproduction, (3) competition for limited resources, and (4) the proliferation of those organisms that are better able to survive and reproduce in the environment.
Students will apply concepts of statistics and probability to support explanations that organisms with an advantageous heritable trait tend to increase in proportion to organisms lacking this trait.
Students will construct an explanation based on evidence for how natural selection leads to adaptation of populations.
Students will evaluate the evidence supporting claims that changes in environmental conditions may result in: (1) increases in the number of individuals of some species, (2) the emergence of new species over time, and (3) the extinction of other species.
Students will analyze a major global challenge to specify qualitative and quantitative criteria and constraints for solutions that account for societal needs and wants.
Students will design a solution to a complex real-world problem by breaking it down into smaller, more manageable problems that can be solved through engineering.
Students will evaluate a solution to a complex real-world problem based on prioritized criteria and trade-offs that account for a range of constraints, including cost, safety, reliability, and aesthetics, as well as possible social, cultural, and environmental impacts.
Students will use a computer simulation to model the impact of proposed solutions to a complex real-world problem with numerous criteria and constraints on interactions within and between systems relevant to the problem.
