Actions

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.

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 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 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

  • 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 matter is composed of atoms and has chemical and physical properties.

6 Force, motion, and energy. The student knows that there is a relationship between force, motion, and energy.

7 Earth and space. The student knows the effects resulting from cyclical movements of the Sun, Earth, and Moon.

8 Earth and space. The student knows characteristics of the universe.

  • 8.A describe components of the universe, including stars, nebulae, and galaxies, and use models such as the Hertzsprung-Russell diagram for classification;

  • 8.B recognize that the Sun is a medium-sized star located in a spiral arm of the Milky Way galaxy and that the Sun is many thousands of times closer to Earth than any other star;

  • 8.C identify how different wavelengths of the electromagnetic spectrum such as visible light and radio waves are used to gain information about components in the universe; and

  • 8.D research how scientific data are used as evidence to develop scientific theories to describe the origin of the universe.

9 Earth and space. The student knows that natural events can impact Earth systems.

10 Earth and space. The student knows that climatic interactions exist among Earth, ocean, and weather systems.

11 Organisms and environments. The student knows that interdependence occurs among living systems and the environment and that human activities can affect these systems.
