11.A.4f.

Using available technology, report, display and defend to an audience conclusions drawn from investigations.

11.B.4a.

Identify a technological design problem inherent in a commonly used product.

11.B.4b.

Propose and compare different solution designs to the design problem based upon given constraints including available tools, materials and time.

11.B.4c.

Develop working visualizations of the proposed solution designs (e.g., blueprints, schematics, flowcharts, cad-cam, animations).

11.B.4d.

Determine the criteria upon which the designs will be judged, identify advantages and disadvantages of the designs and select the most promising design.

11.B.4e.

Develop and test a prototype or simulation of the solution design using available materials, instruments and technology.

11.B.4f.

Evaluate the test results based on established criteria, note sources of error and recommend improvements.

11.B.4g.

Using available technology, report to an audience the relative success of the design based on the test results and criteria.

12.A.4a.

Explain how genetic combinations produce visible effects and variations among physical features and cellular functions of organisms.

12.A.4b.

Describe the structures and organization of cells and tissues that underlie basic life functions including nutrition, respiration, cellular transport, biosynthesis and reproduction.

12.A.4c.

Describe processes by which organisms change over time using evidence from comparative anatomy and physiology, embryology, the fossil record, genetics and biochemistry.

12.B.4a.

Compare physical, ecological and behavioral factors that influence interactions and interdependence of organisms.

12.B.4b.

Simulate and analyze factors that influence the size and stability of populations within ecosystems (e.g., birth rate, death rate, predation, migration patterns).

12.C.4a.

Use kinetic theory, wave theory, quantum theory and the laws of thermodynamics to explain energy transformations.

12.C.4b.

Analyze and explain the atomic and nuclear structure of matter.

12.D.4a.

Explain and predict motions in inertial and accelerated frames of reference.

12.D.4b.

Describe the effects of electromagnetic and nuclear forces including atomic and molecular bonding, capacitance and nuclear reactions.

13.A.4a.

Estimate and suggest ways to reduce the degree of risk involved in science activities.

13.A.4b.

Assess the validity of scientific data by analyzing the results, sample set, sample size, similar previous experimentation, possible misrepresentation of data presented and potential sources of error.

13.A.4c.

Describe how scientific knowledge, explanations and technological designs may change with new information over time (e.g., the understanding of DNA, the design of computers).
