Get to Know the New TEKS BIOLOGY The Texas Essential Knowledge and Skills (TEKS) describe what knowledge areas students should be learning in each subject. Use this guide as a roadmap as you prepare to implement updated TEKS standards in your classroom. Biology TEKS Biology Unchanged Revised TEKS 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: 1A ask questions and define problems based on observations or information from text, phenomena, models, or investigations; 1B apply scientific practices to plan and conduct descriptive, comparative, and experimental investigations and use engineering practices to design solutions to problems; 1C use appropriate safety equipment and practices during laboratory, classroom, and field investigations as outlined in Texas Education Agency-approved safety standards; 1D use appropriate tools such as microscopes, slides, Petri dishes, laboratory glassware, metric rulers, digital balances, pipets, filter paper, micropipettes, gel electrophoresis and polymerase chain reaction (PCR) apparatuses, microcentrifuges, water baths, incubators, thermometers, hot plates, data collection probes, test tube holders, lab notebooks or journals, hand lenses, and models, diagrams, or samples of biological specimens or structures; 1E collect quantitative data using the International System of Units (SI) and qualitative data as evidence; 1F organize quantitative and qualitative data using scatter plots, line graphs, bar graphs, charts, data tables, digital tools, diagrams, scientific drawings, and student-prepared models; 1G develop and use models to represent phenomena, systems, processes, or solutions to engineering problems; and 1H distinguish among scientific hypotheses, theories, and laws. 2 Scientific and engineering practices. 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: 2A identify advantages and limitations of models such as their size, scale, properties, and materials; 2B analyze data by identifying significant statistical features, patterns, sources of error, and limitations; 2C use mathematical calculations to assess quantitative relationships in data; and 2D evaluate experimental and engineering designs. 3 Scientific and engineering practices. The student develops evidence-based explanations and communicates findings, conclusions, and proposed solutions. The student is expected to: 3A develop explanations and propose solutions supported by data and models and consistent with scientific ideas, principles, and theories; 3B communicate explanations and solutions individually and collaboratively in a variety of settings and formats; and 3C engage respectfully in scientific argumentation using applied scientific explanations and empirical evidence. 4 Scientific and engineering practices. The student knows the contributions of scientists and recognizes the importance of scientific research and innovation on society. The student is expected to: 4A analyze, evaluate, and critique scientific explanations and solutions by using empirical evidence, logical reasoning, and experimental and observational testing, so as to encourage critical thinking by the student;
