4.L2.1b: Each gene carries a single unit of information. A single inherited trait of an individual can be determined by one pair or by many pairs of genes. A human cell contains thousands of different genes.
4.L2.1e: In sexual reproduction typically half of the genes come from each parent. Sexually produced offspring are not identical to either parent.
4.L2.2a: In all organisms, genetic traits are passed on from generation to generation.
4.L2.2b: Some genes are dominant and some are recessive. Some traits are inherited by mechanisms other than dominance and recessiveness.

4.L4.3c: Various body structures and functions change as an organism goes through its life cycle.
4.L4.3f: As an individual organism ages, various body structures and functions change.
4.L4.4b: In one type of cell division, chromosomes are duplicated and then separated into two identical and complete sets to be passed to each of the two resulting cells. In this type of cell division, the hereditary information is identical in all the cells that result.
4.L5.1a: Animals and plants have a great variety of body plans and internal structures that contribute to their ability to maintain a balanced condition.
4.L5.1c: All organisms require energy to survive. The amount of energy needed and the method for obtaining this energy vary among cells. Some cells use oxygen to release the energy stored in food.

4.L5.1e: Herbivores obtain energy from plants. Carnivores obtain energy from animals. Omnivores obtain energy from both plants and animals. Decomposers, such as bacteria and fungi, obtain energy by consuming wastes and/or dead organisms.
4.L5.1f: Regulation of an organism's internal environment involves sensing the internal environment and changing physiological activities to keep conditions within the range required for survival. Regulation includes a variety of nervous and hormonal feedback syst
4.L5.1g: The survival of an organism depends on its ability to sense and respond to its external environment.
4.L6.1a: Energy flows through ecosystems in one direction, usually from the Sun, through producers to consumers and then to decomposers. This process may be visualized with food chains or energy pyramids.
4.L6.1b: Food webs identify feeding relationships among producers, consumers, and decomposers in an ecosystem.

4.L6.2a: Photosynthesis is carried on by green plants and other organisms containing chlorophyll. In this process, the Sun's energy is converted into and stored as chemical energy in the form of a sugar. The quantity of sugar molecules increases in green plants during photosynthesis in the presence of sunlight.
4.L6.2b: The major source of atmospheric oxygen is photosynthesis. Carbon dioxide is removed from the atmosphere and oxygen is released during photosynthesis.
4.L6.2c: Green plants are the producers of food which is used directly or indirectly by consumers.
4.L7.1a: A population consists of all individuals of a species that are found together at a given place and time. Populations living in one place form a community. The community and the physical factors with which it interacts compose an ecosystem.
4.L7.1b: Given adequate resources and no disease or predators, populations (including humans) increase. Lack of resources, habitat destruction, and other factors such as predation and climate limit the growth of certain populations in the ecosystem.
4.L7.1c: In all environments, organisms interact with one another in many ways. Relationships among organisms may be competitive, harmful, or beneficial. Some species have adapted to be dependent upon each other with the result that neither could survive without the other.
4.L7.2a: In ecosystems, balance is the result of interactions between community members and their environment.

4.P1.1f: The latitude/longitude coordinate system and our system of time are based on celestial observations.
4.P1.1h: The apparent motions of the Sun, Moon, planets, and stars across the sky can be explained by Earth's rotation and revolution. Earth's rotation causes the length of one day to be approximately 24 hours. This rotation also causes the Sun and Moon to appear to rise along the eastern horizon and to set along the western horizon. Earth's revolution around the Sun defines the length of the year as 365 1/4 days.

4.P4.1c: Most activities in everyday life involve one form of energy being transformed into another. For example, the chemical energy in gasoline is transformed into mechanical energy in an automobile engine. Energy, in the form of heat, is almost always one of the products of energy transformations.
4.P4.1d: Different forms of energy include heat, light, electrical, mechanical, sound, nuclear, and chemical. Energy is transformed in many ways.
4.P4.1e: Energy can be considered to be either kinetic energy, which is the energy of motion, or potential energy, which depends on relative position.
4.P4.2a: Heat moves in predictable ways, flowing from warmer objects to cooler ones, until both reach the same temperature.
4.P4.2b: Heat can be transferred through matter by the collisions of atoms and/or molecules (conduction) or through space (radiation). In a liquid or gas, currents will facilitate the transfer of heat (convection).
4.P4.2c: During a phase change, heat energy is absorbed or released. Energy is absorbed when a solid changes to a liquid and when a liquid changes to a gas. Energy is released when a gas changes to a liquid and when a liquid changes to a solid.
4.P4.4a: Different forms of electromagnetic energy have different wavelengths. Some examples of electromagnetic energy are microwaves, infrared light, visible light, ultraviolet light, X-rays, and gamma rays.
4.P4.4b: Light passes through some materials, sometimes refracting in the process. Materials absorb and reflect light, and may transmit light. To see an object, light from that object, emitted by or reflected from it, must enter the eye.
4.P4.4c: Vibrations in materials set up wave-like disturbances that spread away from the source. Sound waves are an example. Vibrational waves move at different speeds in different materials. Sound cannot travel in a vacuum.

4.P5.1b: The motion of an object can be described by its position, direction of motion, and speed.
4.P5.1c: An object's motion is the result of the combined effect of all forces acting on the object. A moving object that is not subjected to a force will continue to move at a constant speed in a straight line. An object at rest will remain at rest.
4.P5.1d: Force is directly related to an object's mass and acceleration. The greater the force, the greater the change in motion.
4.P5.1e: For every action there is an equal and opposite reaction.
