SCI.9-12.L.1.1.1.a: Science

Scientific explanations are built by combining evidence that can be observed with what people already know about the world.

SCI.9-12.L.1.1.1.b: Science

Learning about the historical development of scientific concepts or about individuals who have contributed to scientific knowledge provides a better understanding of scientific inquiry and the relationship between science and society.

SCI.9-12.L.1.1.1.c: Science

Science provides knowledge, but values are also essential to making effective and ethical decisions about the application of scientific knowledge.

SCI.9-12.L.1.1.2.a: Science

Inquiry involves asking questions and locating, interpreting, and processing information from a variety of sources.

SCI.9-12.L.1.1.2.b: Science

Inquiry involves making judgments about the reliability of the source and relevance of information.

SCI.9-12.L.1.1.3.a: Science

Scientific explanations are accepted when they are consistent with experimental and observational evidence and when they lead to accurate predictions.

SCI.9-12.L.1.1.3.b: Science

All scientific explanations are tentative and subject to change or improvement. Each new bit of evidence can create more questions than it answers. This leads to increasingly better understanding of how things work in the living world.

SCI.9-12.L.1.1.4.a: Science

Well-accepted theories are ones that are supported by different kinds of scientific investigations often involving the contributions of individuals from different disciplines.

SCI.9-12.L.1.2.1: Science

Devise ways of making observations to test proposed explanations.

SCI.9-12.L.1.2.2.a: Science

Development of a research plan involves researching background information and understanding the major concepts in the area being investigated. Recommendations for methodologies, use of technologies, proper equipment, and safety precautions should also be included.

SCI.9-12.L.1.2.3.a: Science

Hypotheses are predictions based upon both research and observation.

SCI.9-12.L.1.2.3.b: Science

Hypotheses are widely used in science for determining what data to collect and as a guide for interpreting the data.

SCI.9-12.L.1.2.3.c: Science

Development of a research plan for testing a hypothesis requires planning to avoid bias (e.g., repeated trials, large sample size, and objective data-collection techniques).

SCI.9-12.L.1.2.4: Science

Carry out a research plan for testing explanations, including selecting and developing techniques, acquiring and building apparatus, and recording observations as necessary.

SCI.9-12.L.1.3.1.a: Science

Interpretation of data leads to development of additional hypotheses, the formulation of generalizations, or explanations of natural phenomena.

SCI.9-12.L.1.3.2: Science

Apply statistical analysis techniques when appropriate to test if chance alone explains the results.

SCI.9-12.L.1.3.3: Science

Assess correspondence between the predicted result contained in the hypothesis and actual result, and reach a conclusion as to whether the explanation on which the prediction was based is supported.

SCI.9-12.L.1.3.4.a: Science

Hypotheses are valuable, even if they turn out not to be true, because they may lead to further investigation.

SCI.9-12.L.1.3.4.b: Science

Claims should be questioned if the data are based on samples that are very small, biased, or inadequately controlled or if the conclusions are based on the faulty, incomplete, or misleading use of numbers.

SCI.9-12.L.1.3.4.c: Science

Claims should be questioned if fact and opinion are intermingled, if adequate evidence is not cited, or if the conclusions do not follow logically from the evidence given.

SCI.9-12.L.1.3.5.a: Science

One assumption of science is that other individuals could arrive at the same explanation if they had access to similar evidence. Scientists make the results of their investigations public; they should describe the investigations in ways that enable others to repeat the investigations.

SCI.9-12.L.1.3.5.b: Science

Scientists use peer review to evaluate the results of scientific investigations and the explanations proposed by other scientists. They analyze the experimental procedures, examine the evidence, identify faulty reasoning, point out statements that go beyond the evidence, and suggest alternative explanations for the same observations.

SCI.9-12.L.4.1.1.a: Science

Populations can be categorized by the function they serve. Food webs identify the relationships among producers, consumers, and decomposers carrying out either autotropic or heterotropic nutrition.

SCI.9-12.L.4.1.1.b: Science

An ecosystem is shaped by the nonliving environment as well as its interacting species. The world contains a wide diversity of physical conditions, which creates a variety of environments.

SCI.9-12.L.4.1.1.c: Science

In all environments, organisms compete for vital resources. The linked and changing interactions of populations and the environment compose the total ecosystem.

SCI.9-12.L.4.1.1.d: Science

The interdependence of organisms in an established ecosystem often results in approximate stability over hundreds and thousands of years. For example, as one population increases, it is held in check by one or more environmental factors or another species.

SCI.9-12.L.4.1.1.e: Science

Ecosystems, like many other complex systems, tend to show cyclic changes around a state of approximate equilibrium.

SCI.9-12.L.4.1.1.f: Science

Every population is linked, directly or indirectly, with many others in an ecosystem. Disruptions in the numbers and types of species and environmental changes can upset ecosystem stability.

SCI.9-12.L.4.1.2.a: Science

Important levels of organization for structure and function include organelles, cells, tissues, organs, organ systems, and whole organisms.

SCI.9-12.L.4.1.2.f: Science

Cells have particular structures that perform specific jobs. These structures perform the actual work of the cell. Just as systems are coordinated and work together, cell parts must also be coordinated and work together.

SCI.9-12.L.4.1.2.g: Science

Each cell is covered by a membrane that performs a number of important functions for the cell. These include: separation from its outside environment, controlling which molecules enter and leave the cell, and recognition of chemical signals. The processes of diffusion and active transport are important in the movement of materials in and out of cells.

SCI.9-12.L.4.1.2.h: Science

Many organic and inorganic substances dissolved in cells allow necessary chemical reactions to take place in order to maintain life. Large organic food molecules such as proteins and starches must initially be broken down (digested to amino acids and simple sugars respectively), in order to enter cells. Once nutrients enter a cell, the cell will use them as building blocks in the synthesis of compounds necessary for life.

SCI.9-12.L.4.1.2.i: Science

Inside the cell a variety of specialized structures, formed from many different molecules, carry out the transport of materials (cytoplasm), extraction of energy from nutrients (mitochondria), protein building (ribosomes), waste disposal (cell membrane), storage (vacuole), and information storage (nucleus).

SCI.9-12.L.4.6.1.a: Science

Energy flows through ecosystems in one direction, typically from the Sun, through photosynthetic organisms including green plants and algae, to herbivores to carnivores and decomposers.

SCI.9-12.L.4.6.1.b: Science

The atoms and molecules on the Earth cycle among the living and nonliving components of the biosphere. For example, carbon dioxide and water molecules used in photosynthesis to form energy-rich organic compounds are returned to the environment when the energy in these compounds is eventually released by cells. Continual input of energy from sunlight keeps the process going. This concept may be illustrated with an energy pyramid.

SCI.9-12.L.4.6.1.c: Science

The chemical elements, such as carbon, hydrogen, nitrogen, and oxygen, that make up the molecules of living things pass through food webs and are combined and recombined in different ways. At each link in a food web, some energy is stored in newly made structures but much is dissipated into the environment as heat.

SCI.9-12.L.4.6.1.d: Science

The number of organisms any habitat can support (carrying capacity) is limited by the available energy, water, oxygen, and minerals, and by the ability of ecosystems to recycle the residue of dead organisms through the activities of bacteria and fungi.

SCI.9-12.L.4.6.1.e: Science

In any particular environment, the growth and survival of organisms depend on the physical conditions including light intensity, temperature range, mineral availability, soil/rock type, and relative acidity (pH).

SCI.9-12.L.4.6.1.f: Science

Living organisms have the capacity to produce populations of unlimited size, but environments and resources are finite. This has profound effects on the interactions among organisms.

SCI.9-12.L.4.6.1.g: Science

Relationships between organisms may be negative, neutral, or positive. Some organisms may interact with one another in several ways. They may be in a producer/consumer, predator/prey, or parasite/host relationship; or one organism may cause disease in, scavenge, or decompose another.

SCI.9-12.L.4.6.2.a: Science

As a result of evolutionary processes, there is a diversity of organisms and roles in ecosystems. This diversity of species increases the chance that at least some will survive in the face of large environmental changes. Biodiversity increases the stability of the ecosystem.

SCI.9-12.L.4.6.2.b: Science

Biodiversity also ensures the availability of a rich variety of genetic material that may lead to future agricultural or medical discoveries with significant value to humankind. As diversity is lost, potential sources of these materials may be lost with it.

SCI.9-12.L.4.6.3.a: Science

The interrelationships and interdependencies of organisms affect the development of stable ecosystems.

SCI.9-12.L.4.6.3.b: Science

Through ecological succession, all ecosystems progress through a sequence of changes during which one ecological community modifies the environment, making it more suitable for another community. These long-term gradual changes result in the community reaching a point of stability that can last for hundreds or thousands of years.

SCI.9-12.L.4.6.3.c: Science

A stable ecosystem can be altered, either rapidly or slowly, through the activities of organisms (including humans), or through climatic changes or natural disasters. The altered ecosystem can usually recover through gradual changes back to a point of long- term stability.
