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.
1.A demonstrate safe practices during laboratory and field investigations as outlined in Texas Education Agency-approved safety standards; and
1.B practice appropriate use and conservation of resources, including disposal, reuse, or recycling of materials.
2 Scientific investigation and reasoning. The student uses scientific practices during laboratory and field investigations.
2.A plan and implement comparative and descriptive investigations by making observations, asking well defined questions, and using appropriate equipment and technology;
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.
3.A analyze, evaluate, and critique scientific explanations by using empirical evidence, logical reasoning, and experimental and observational testing, so as to encourage critical thinking by the student;
3.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.
4.A 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; and
4.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.
5.A know that an element is a pure substance represented by a chemical symbol and that a compound is a pure substance represented by a chemical formula;
6.C test the physical properties of minerals, including hardness, color, luster, and streak.
7 Matter and energy. The student knows that some of Earth's energy resources are available on a nearly perpetual basis, while others can be renewed over a relatively short period of time. Some energy resources, once depleted, are essentially nonrenewable.
7.A research and discuss the advantages and disadvantages of using coal, oil, natural gas, nuclear power, biomass, wind, hydropower, geothermal, and solar resources.
11.B understand that gravity is the force that governs the motion of our solar system; and
11.C describe the history and future of space exploration, including the types of equipment and transportation needed for space travel.
12 Organisms and environments. The student knows all organisms are classified into domains and kingdoms. Organisms within these taxonomic groups share similar characteristics that allow them to interact with the living and nonliving parts of their ecosystem.
12.A understand that all organisms are composed of one or more cells;
12.B recognize that the presence of a nucleus is a key factor used to determine whether a cell is prokaryotic or eukaryotic;
12.C recognize that the broadest taxonomic classification of living organisms is divided into currently recognized domains;
12.D identify the basic characteristics of organisms, including prokaryotic or eukaryotic, unicellular or multicellular, autotrophic or heterotrophic, and mode of reproduction, that further classify them in the currently recognized kingdoms;
