Scientific Processes, Safety & Procedures

TEKS:

6.1a Students will demonstrate safe practices during laboratory and field investigations as outlined in the Texas Education Agency-approved safety standards.

6.1b Practice appropriate use and conservation of resources, including disposal, reuse, or recycling of materials.

6.2a Plan and implement comparative and descriptive investigations by making observations, asking well defined questions, and using appropriate equipment and technology.

6.2b Design and implement experimental investigations by making observations, asking well defined questions, formulating testable hypotheses, and using appropriate equipment and technology.

6.2c Collect and record data using the International System of Units (SI) and qualitative means such as labeled drawings, writing, and graphic organizers.

6.2d Construct tables and graphs, using repeated trials and means, to organize data and identify patterns.

6.2e Analyze data to formulate reasonable explanations, communicate valid conclusions supported by the data, and predict trends.

6.3a Analyze, evaluate, and critique scientific explanations by using empirical evidence, logical reasoning, and experimental and observational testing, so as to encourage critical thinking by the student.

6.3b Use models to represent aspects of the natural world such as a model of Earth's layers.

6.3c Identify advantages and limitations of models such as size, scale, properties, and materials.

6.3d Relate the impact of research on scientific thought and society, including the history of science and contributions of scientists as related to the content.

6.4a Students will use appropriate tools to collect, record, and analyze information, including journals/notebooks and other equipment as needed.

6.4b Students will use preventative safety equipment, including chemical splash goggles, aprons, and gloves, and be prepared to use emergency safety equipment, including an eye/face wash, a fire blanket, and a fire extinguisher.
