Ongoing TEKS
Ongoing TEKS
6.1A [Process Standard] Demonstrate safe practices during laboratory and field investigations as outlined in TEA approved safety standards.
6.2A [Process Standard] Plan and implement comparative and descriptive investigations by making observations, asking well-defined questions, and using appropriate equipment and technology.
6.2B [Process Standard] Design and implement experimental investigations by making observations, asking well defined questions, formulating testable hypotheses, and using appropriate equipment and technology.
6.2C [Process Standard] Collect and record data using the International System of Units (SI) and qualitative means such as labeled drawings, writing, and graphic organizers.
6.3A [Process Standard] In all fields of science, analyze, evaluate, and critique scientific explanations by using empirical evidence, logical reasoning, and experimental and observational testing, including examining all sides of scientific evidence of those scientific explanations, so as to encourage critical thinking by the student.
6.3D [Process Standard] 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 [Process Standard] Use appropriate tools , including journals/notebooks, beakers, Petri dishes, meter sticks, graduated cylinders, hot plates, test tubes, balances, microscopes, thermometers, calculators, computers, timing devices, and other necessary equipment to collect, record, and analyze information.
Student Learning Targets:
