|SEP-1: Asking Questions and Defining Problems
Ask questions that arise from careful observation of phenomena, or unexpected results, to clarify and/or seek additional information
SEP-2: Developing and Using Models
Develop, revise, and/or use a model based on evidence to illustrate and/or predict the relationships between systems or between components of a system.
SEP-6: Constructing Explanations and Designing Solutions
Construct and revise explanations based on valid and reliable evidence obtained from a variety of sources (including students’ own investigations, models, theories, simulations, peer review) and the assumptions that theories and laws that describe the natural world operate today as they did in the past and will continue to do so in the future.
Apply scientific reasoning, theory, and/or models to link evidence to the claims to assess the extent to which the reasoning and data support the explanation or conclusion.
|LS1.A: Structure and Function
All cells contain genetic information in the form of DNA molecules. Genes are regions in the DNA that contain the instructions that code for the formation of proteins, which carry out most of the work of cells.
Feedback mechanisms maintain a living system’s internal conditions within certain limits and mediate behaviors, allow it to remain alive and functional even as external conditions change within some range.
LS2.C: Ecosystems Dynamics, Functioning, and Resilience
If a biological or physical disturbance to an ecosystem occurs, including one induced by human activity, the ecosystem may return to its more or less original state or become a very different ecosystem, depending on the complex set of interactions within the ecosystem.
LS3.A: Inheritance of Traits
DNA carries instructions for forming species’ characteristics. Each cell in an organism has the same genetic content, but genes expressed by cells can differ.
ESS3.C: Human Impacts on Earth Systems
Sustainability of human societies and of the biodiversity that supports them requires responsible management of natural resources, including the development of technologies.
|CCC-2: Cause and Effect
Empirical evidence is required to differentiate between cause and correlation and make claims about specific causes and effects.
CCC-4: Systems and System Models
Models (e.g., physical, mathematical, computer models) can be used to simulate systems and interactions – including energy, matter, and information flows – within and between systems at different scales.
CCC-6: Structure and Function
Investigating or designing new systems or structures requires a detailed examination of the properties of different materials, the structures of different components, and connections of components to reveal their function and/or solve a problem.
CCC-7: Stability and Change
Feedback (negative or positive) can stabilize or destabilize a system.
