Incorporated into 40% of STAAR test questions

8.1A demonstrate safe practices during laboratory and dield Investigations as outlined in Texas safety standards.
8.1B practice appropriate use and conservation of resources, including disposal, reuse, or recycling materials.
8.2A plan and implement comparative and descriptive investigations by making observations, asking well-defined questions, and using appropriate equipment and technology.
8.2B design and implement comparative and experimental investigations by making observations, aking well-defined questions, formulating testable hypothesis, and using appropriate equiment and technology.
8.2C collect and record data using hte Internanation system of Units (SI) and qualitative means such as labeled drawings, writing, and graphic organizers.
8.2D construct tables and graphs, using repeated trials and means, to organize data and identify patterns.
8.2E analyze data to formulate reasonable explanations, communicate valid conclusions supported by the data, and predict trends.
8.3A in all fields of science, analyze, evaluate, and critique scientific explanations by using emepirical evidence, logical reasoning, and experimental and observational testing, including examining all sides of scientific evidence of those scientific explanations, so as to encourae critical thinking by the student.
8.3B use models to represent aspects of the natural world such as an atom, molecule, space, or a geologic feature.
8.3C identify advantages and limitations of models such as size, scale, properties, and materials.
8.3D relate the impact of research on scientific thought and society, including the history of science and contributions of scientists as related to the content.
8.4A use appropriate tools to collect, record, and analyze information, including lab journals/notebooks, beakers, meter sticks, gratuated cylinders, anemometers, psychrometers, hot plates, test tubes, spring scales, balances, microscopes, thermometers, calculators, computers, spectroscopes, timing devices, and other equipment as needed to teach the curriculum.
