Mrs.Wall-Lopez's Class

(1)  Scientific investigation and reasoning. The student, for at least 40% of instructional time, conducts laboratory and field investigations following safety procedures and environmentally appropriate and ethical practices. The student is expected to:

(A)  demonstrate safe practices during laboratory and field investigations as outlined in the Texas Safety Standards; and

(B)  practice appropriate use and conservation of resources, including disposal, reuse, or recycling of materials.

 

(2)  Scientific investigation and reasoning. The student uses scientific inquiry methods during laboratory and field investigations. The student is expected to:

(A)  plan and implement comparative and descriptive investigations by making observations, asking well-defined questions, and using appropriate equipment and technology;

(B)  design and implement experimental investigations by making observations, asking well-defined questions, formulating testable hypotheses, and using appropriate equipment and technology;

(C)  collect and record data using the International System of Units (SI) and qualitative means such as labeled drawings, writing, and graphic organizers;

(D)  construct tables and graphs, using repeated trials and means, to organize data and identify patterns; and

(E)  analyze data to formulate reasonable explanations, communicate valid conclusions supported by the data, and predict trends.

 

(3)  Scientific investigation and reasoning. The student uses critical thinking, scientific reasoning, and problem solving to make informed decisions and knows the contributions of relevant scientists. The student is expected to:

(A)  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;

(B)  use models to represent aspects of the natural world such as a model of Earth's layers;

(C)  identify advantages and limitations of models such as size, scale, properties, and materials; and

(D)  relate the impact of research on scientific thought and society, including the history of science and contributions of scientists as related to the content.

 

(4)  Scientific investigation and reasoning. The student knows how to use a variety of tools and safety equipment to conduct science inquiry. The student is expected to:

(A)  use appropriate tools to collect, record, and analyze information, including journals/notebooks, beakers, Petri dishes, meter sticks, graduated cylinders, hot plates, test tubes, triple beam balances, microscopes, thermometers, calculators, computers, timing devices, and other equipment as needed to teach the curriculum; and

(B)  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.

 

(5)  Matter and energy. The student knows the differences between elements and compounds. The student is expected to:

(A)  know that an element is a pure substance represented by chemical symbols;

(B)  recognize that a limited number of the many known elements comprise the largest portion of solid Earth, living matter, oceans, and the atmosphere;

(C)  differentiate between elements and compounds on the most basic level; and

(D)  identify the formation of a new substance by using the evidence of a possible chemical change such as production of a gas, change in temperature, production of a precipitate, or color change.

 

(6)  Matter and energy. The student knows matter has physical properties that can be used for classification. The student is expected to:

(A)  compare metals, nonmetals, and metalloids using physical properties such as luster, conductivity, or malleability;

(B)  calculate density to identify an unknown substance; and
