3.6.11 Earth and space. The student understands the organization of our solar system and the relationships among the various bodies that comprise it.
3.6.11.B understand that gravity is the force that governs the motion of our solar system.
4 Organisms and Environments
4.8.11 Organisms and environments. The student knows that interdependence occurs among living systems and the environment and that human activities can affect these systems.
4.8.11.A investigate how organisms and populations in an ecosystem depend on and may compete for biotic factors such as food and abiotic factors such as quantity of light, water, range of temperatures, or soil composition;
4.8.11.B explore how short- and long-term environmental changes affect organisms and traits in subsequent populations; and
4.7.11 Organisms and environments. The student knows that populations and species demonstrate variation and inherit many of their unique traits through gradual processes over many generations.
4.7.11.A examine organisms or their structures such as insects or leaves and use dichotomous keys for identification; and
4.7.11.C identify some changes in genetic traits that have occurred over several generations through natural selection and selective breeding such as the Galapagos Medium Ground Finch (Geospiza fortis) or domestic animals and hybrid plants.
4.7.12 Organisms and environments. The student knows that living systems at all levels of organization demonstrate the complementary nature of structure and function.
4.7.12.B identify the main functions of the systems of the human organism, including the circulatory, respiratory, skeletal, muscular, digestive, excretory, reproductive, integumentary, nervous, and endocrine systems;
4.6.12 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.
4.6.12.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.
SIRS Scientific Investigation and Reasoning Skills
SIRS.8.1 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.
SIRS.8.1.A demonstrate safe practices during laboratory and field investigations as outlined in Texas Education Agency-approved safety standards; and
SIRS.8.1.B practice appropriate use and conservation of resources, including disposal, reuse, or recycling of materials.
SIRS.8.2 Scientific investigation and reasoning. The student uses scientific practices during laboratory and field investigations.
SIRS.8.2.A plan and implement comparative and descriptive investigations by making observations, asking well defined questions, and using appropriate equipment and technology;
SIRS.8.3 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.
SIRS.8.3.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;
SIRS.8.3.B use models to represent aspects of the natural world such as an atom, a molecule, space, or a geologic feature;
SIRS.8.3.C identify advantages and limitations of models such as size, scale, properties, and materials; and
SIRS.8.3.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.
SIRS.8.4 Scientific investigation and reasoning. The student knows how to use a variety of tools and safety equipment to conduct science inquiry.
SIRS.8.4.A use appropriate tools, including lab journals/notebooks, beakers, meter sticks, graduated cylinders, anemometers, psychrometers, hot plates, test tubes, spring scales, balances, microscopes, thermometers, calculators, computers, spectroscopes, timing devices, and other necessary equipment to collect, record, and analyze information; and
SIRS.8.4.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.
