1-4 Scientific and engineering practices

  • 1 The student asks questions, identifies problems, and plans and safely conducts classroom, laboratory, and field investigations to answer questions, explain phenomena, or design solutions using appropriate tools and models. The student is expected to:

    • A ask questions and define problems based on observations or information from text, phenomena, models, or investigations;

    • B use scientific practices to plan and conduct descriptive investigations and use engineering practices to design solutions to problems;

    • C demonstrate safe practices and the use of safety equipment during classroom and field investigations as outlined in Texas Education Agency-approved safety standards;

    • D use tools, including hand lenses; metric rulers; Celsius thermometers; wind vanes; rain gauges; graduated cylinders; beakers; digital scales; hot plates; meter sticks; magnets; notebooks; Sun, Earth, Moon system models; timing devices; materials to support observation of habitats of organisms such as terrariums, aquariums, and collecting nets; and materials to support digital data collection such as computers, tablets, and cameras, to observe, measure, test, and analyze information;

    • E collect observations and measurements as evidence;

    • F construct appropriate graphic organizers to collect data, including tables, bar graphs, line graphs, tree maps, concept maps, Venn diagrams, flow charts or sequence maps, and input-output tables that show cause and effect; and

    • G develop and use models to represent phenomena, objects, and processes or design a prototype for a solution to a problem.

  • 2 The student analyzes and interprets data to derive meaning, identify features and patterns, and discover relationships or correlations to develop evidence-based arguments or evaluate designs. The student is expected to:

  • 3 The student develops evidence-based explanations and communicates findings, conclusions, and proposed solutions. The student is expected to:

    • A develop explanations and propose solutions supported by data and models;

    • B communicate explanations and solutions individually and collaboratively in a variety of settings and formats; and

    • C listen actively to others' explanations to identify relevant evidence and engage respectfully in scientific discussion.

  • 4 The student knows the contributions of scientists and recognizes the importance of scientific research and innovation for society. The student is expected to:

    • A explain how scientific discoveries and innovative solutions to problems impact science and society; and

    • B research and explore resources such as museums, libraries, professional organizations, private companies, online platforms, and mentors employed in a science, technology, engineering, and mathematics (STEM) field to investigate STEM careers.
