Essential Knowledge and Skills (TEKS)
112.23.6: The student knows that there is a relationship between force and motion.
112.23.6.A: demonstrate basic relationships between force and motion using simple machines including pulleys and levers;
112.23.6.B: demonstrate that an object will remain at rest or move at a constant speed and in a straight line if it is not being subjected to an unbalanced force;
112.23.6.C: relate forces to basic processes in living organisms including the flow of blood and the emergence of seedlings.
112.23.7: The student knows that substances have physical and chemical properties.
112.23.7.B: describe physical properties of elements and identify how they are used to position an element on the periodic table;
112.23.8: The student knows that complex interactions occur between matter and energy.
112.23.8.A: illustrate examples of potential and kinetic energy in everyday life such as objects at rest, movement of geologic faults, and falling water;
112.23.8.B: identify that radiant energy from the Sun is transferred into chemical energy through the process of photosynthesis.
112.23.9: The student knows the relationship between structure and function in living systems.
112.23.9.A: identify the systems of the human organism and describe their functions;
112.23.9.B: describe how organisms maintain stable internal conditions while living in changing external environments.
112.23.10: The student knows that species can change through generations and that the instructions for traits are contained in the genetic material of the organisms.
112.23.10.A: identify that sexual reproduction results in more diverse offspring and asexual reproduction results in more uniform offspring;
112.23.10.B: compare traits of organisms of different species that enhance their survival and reproduction;
112.23.10.C: distinguish between dominant and recessive traits and recognize that inherited traits of an individual are contained in genetic material.
112.23.11: The student knows that the responses of organisms are caused by internal or external stimuli.
112.23.11.B: identify responses in organisms to external stimuli found in the environment such as the presence or absence of light.
112.23.12: The student knows that there is a relationship between organisms and the environment.
112.23.12.A: identify components of an ecosystem;
112.23.12.B: observe and describe how organisms including producers, consumers, and decomposers live together in an environment and use existing resources;
112.23.12.D: observe and describe the role of ecological succession in ecosystems.
112.23.13: The student knows components of our solar system.
112.23.13.A: identify and illustrate how the tilt of the Earth on its axis as it rotates and revolves around the Sun causes changes in seasons and the length of a day;
112.23.13.B: relate the Earth's movement and the moon's orbit to the observed cyclical phases of the moon.
112.23.14: The student knows that natural events and human activity can alter Earth systems.
112.23.14.A: describe and predict the impact of different catastrophic events on the Earth;
112.23.14.B: analyze effects of regional erosional deposition and weathering;
