1 Scientific investigation and reasoning. The student, for at least 40% of the 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 Science 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 life science models, hand lenses, stereoscopes, microscopes, beakers, Petri dishes, microscope slides, graduated cylinders, test tubes, meter sticks, metric rulers, metric tape measures, timing devices, hot plates, balances, thermometers, calculators, water test kits, computers, temperature and pH probes, collecting nets, insect traps, globes, digital cameras, journals/notebooks, 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 that interactions occur between matter and energy.
5.A recognize that radiant energy from the Sun is transformed into chemical energy through the process of photosynthesis; and
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.
11.A examine organisms or their structures such as insects or leaves and use dichotomous keys for identification;
11.B explain variation within a population or species by comparing external features, behaviors, or physiology of organisms that enhance their survival such as migration, hibernation, or storage of food in a bulb; and
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.
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;
