1a. Select and use appropriate tools and technology (such as computer-linkedprobes, spreadsheets, and graphing calculators) to perform tests, collect data,analyze relationships, and display data.

1b. Identify and communicate sources of unavoidable experimental error.

1c. Identify possible reasons for inconsistent results, such as sources oferror or uncontrolled conditions.

1d. Formulate explanations by using logic and evidence.

1e. Solve scientific problems by using quadratic equations and simpletrigonometric, exponential, and logarithmic functions.

1f. Distringuish between hypothesisand theory as scientific terms.

1g. Recognize the usefulness and limitations of models and theories asscientific representations of reality.

1h. Read and interpret topographic and geologic maps.

1i. Analyze the locations, sequences, or time intervals that arecharacteristic of natural phenomena (eg., relative ages of rocks, locations ofplanets over time, and succession of species in an ecosystem).

1j. Recognize the issues of statistical variability and the need forcontrolled tests.

1k. Recognize the cumulative nature of scientific evidence.

1l. Analyze situations and solve problems that require combining andapplying concepts from more than one area of science.

1m. Investigate a science-based societal issue by researching theliterature, analyzing data, and communicating the findings.Examples of issues include irradiation offood, cloning of animals by somatic cell nuclear transfer, choice of energysources, and land and water use decisions in California.
