112.22.5: The student knows that systems may combine with other systems to form a larger system.
112.22.5.A: identify and describe a system that results from the combination of two or more systems such as in the solar system;
112.22.6: The student knows that there is a relationship between force and motion.
112.22.6.A: identify and describe the changes in position, direction of motion, and speed of an object when acted upon by force;
112.22.6.B: demonstrate that changes in motion can be measured and graphically represented;
112.22.6.C: identify forces that shape features of the Earth including uplifting, movement of water, and volcanic activity.
112.22.7: The student knows that substances have physical and chemical properties.
112.22.7.A: demonstrate that new substances can be made when two or more substances are chemically combined and compare the properties of the new substances to the original substances;
112.22.7.B: classify substances by their physical and chemical properties.
112.22.8: The student knows that complex interactions occur between matter and energy.
112.22.8.B: explain and illustrate the interactions between matter and energy in the water cycle and in the decay of biomass such as in a compost bin;
112.22.8.C: describe energy flow in living systems including food chains and food webs.
112.22.9: The student knows that obtaining, transforming, and distributing energy affects the environment.
112.22.9.A: identify energy transformations occurring during the production of energy for human use such as electrical energy to heat energy or heat energy to electrical energy;
112.22.9.B: compare methods used for transforming energy in devices such as water heaters, cooling systems, or hydroelectric and wind power plants;
112.22.10: The student knows the relationship between structure and function in living systems.
112.22.10.A: differentiate between structure and function;
112.22.10.B: determine that all organisms are composed of cells that carry on functions to sustain life;
112.22.10.C: identify how structure complements function at different levels of organization including organs, organ systems, organisms, and populations.
112.22.11: The student knows that traits of species can change through generations and that the instructions for traits are contained in the genetic material of the organisms.
112.22.11.A: identify some changes in traits that can occur over several generations through natural occurrence and selective breeding;
112.22.11.B: identify cells as structures containing genetic material;
112.22.11.C: interpret the role of genes in inheritance.
112.22.12: The student knows that the responses of organisms are caused by internal or external stimuli.
112.22.12.B: identify responses in organisms to external stimuli such as the presence or absence of heat or light;
112.22.12.C: identify components of an ecosystem to which organisms may respond.
112.22.13: The student knows components of our solar system.
112.22.13.A: identify characteristics of objects in our solar system including the Sun, planets, meteorites, comets, asteroids, and moons;
112.22.14: The student knows the structures and functions of Earth systems.
112.22.14.A: summarize the rock cycle;
112.22.14.B: identify relationships between groundwater and surface water in a watershed;
