112.27(b)(1)
Scientific and engineering practices
The student, for at least 40% of instructional time, 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:
-
112.27(b)(1)(A)
ask questions and define problems based on observations or information from text, phenomena, models, or investigations; ask
-
112.27(b)(1)(B)
use scientific practices to plan and conduct descriptive, comparative, and experimental investigations and use engineering practices to design solutions to problems; use
-
112.27(b)(1)(C)
use appropriate safety equipment and practices during laboratory, classroom, and field investigations as outlined in Texas Education Agency-approved safety standards; use
-
112.27(b)(1)(D)
use appropriate tools such as graduated cylinders, metric rulers, periodic tables, balances, scales, thermometers, temperature probes, laboratory ware, timing devices, pH indicators, hot plates, models, microscopes, slides, life science models, petri dishes, dissecting kits, magnets, spring scales or force sensors, tools that model wave behavior, satellite images, hand lenses, and lab notebooks or journals; use
-
112.27(b)(1)(E)
collect quantitative data using the International System of Units (SI) and qualitative data as evidence; collect
-
112.27(b)(1)(F)
construct appropriate tables, graphs, maps, and charts using repeated trials and means to organize data; construct
-
112.27(b)(1)(G)
develop and use models to represent phenomena, systems, processes, or solutions to engineering problems; and develop
