Actions

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.

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.

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.

6 Matter and energy. The student knows that matter has physical and chemical properties and can undergo physical and chemical changes.

7 Force, motion, and energy. The student knows that there is a relationship among force, motion, and energy.

8 Earth and space. The student knows that natural events and human activity can impact Earth systems.

  • 8.A predict and describe how catastrophic events such as floods, hurricanes, or tornadoes impact ecosystems;

  • 8.B analyze the effects of weathering, erosion, and deposition on the environment in ecoregions of Texas; and

  • 8.C model the effects of human activity on groundwater and surface water in a watershed.

9 Earth and space. The student knows components of our solar system.

10 Organisms and environments. The student knows that there is a relationship between organisms and the environment.

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.

12 Organisms and environments. The student knows that living systems at all levels of organization demonstrate the complementary nature of structure and function.

13 Organisms and environments. The student knows that a living organism must be able to maintain balance in stable internal conditions in response to external and internal stimuli.

  • 13.A investigate how organisms respond to external stimuli found in the environment such as phototropism and fight or flight; and

  • 13.B describe and relate responses in organisms that may result from internal stimuli such as wilting in plants and fever or vomiting in animals that allow them to maintain balance.

14 Organisms and environments. The student knows that reproduction is a characteristic of living organisms and that the instructions for traits are governed in the genetic material.
