Grade	Discipline	Core Idea
PreK-2	LS2.A: Interdependent relationships in ecosystems	Plants depend on water and light to grow, and also depend on animals for pollination or to move their seeds around.
3-5	LS2.A: Interdependent relationships in ecosystems	The food of almost any animal can be traced back to plants. Organisms are related in food webs in which some animals eat plants for food and other animals eat the animals that eat plants, while decomposers restore some materials back to the soil.
6-8	LS2.A: Interdependent relationships in ecosystems	Organisms and populations are dependent on their environmental interactions both with other living things and with nonliving factors, any of which can limit their growth. Competitive, predatory, and mutually beneficial interactions vary across ecosystems but the patterns are shared.
9-12	LS2.A: Interdependent relationships in ecosystems	Ecosystems have carrying capacities resulting from biotic and abiotic factors. The fundamental tension between resource availability and organism populations affects the abundance of species in any given ecosystem.
9-12	LS2.C: Ecosystem dynamics, functioning, and resilience	If a biological or physical disturbance to an ecosystem occurs, including one induced by human activity, the ecosystem may return to its more or less original state or become a very different ecosystem, depending on the complex set of interactions within the ecosystem.
PreK-2	PS1.A: Structure of matter (includes PS1.C Nuclear Processes)	Matter exists as different substances that have observable different properties. Different properties are suited to different purposes. Objects can be built up from smaller parts.
3-5	PS1.A: Structure of matter (includes PS1.C Nuclear Processes)	Matter exists as particles that are too small to see, and so matter is always conserved even if it seems to disappear. Measurements of a variety of observable properties can be used to identify particular materials.
6-8	PS1.A: Structure of matter (includes PS1.C Nuclear Processes)	The fact that matter is composed of atoms and molecules can be used to explain the properties of substances, diversity of materials, states of matter, phase changes, and conservation of matter.
9-12	PS1.A: Structure of matter (includes PS1.C Nuclear Processes)	The sub-atomic structural model and interactions between electric charges at the atomic scale can be used to explain the structure and interactions of matter, including chemical reactions and nuclear processes. Repeating patterns of the periodic table reflect patterns of outer electrons. A stable molecule has less energy than the same set of atoms separated; one must provide at least this energy to take the molecule apart.
PreK-2	PS1.B: Chemical reactions	Heating and cooling substances cause changes that are sometimes reversible and sometimes not.
3-5	PS1.B: Chemical reactions	Chemical reactions that occur when substances are mixed can be identified by the emergence of substances with different properties; the total mass remains the same.
6-8	PS1.B: Chemical reactions	Reacting substances rearrange to form different molecules, but the number of atoms is conserved. Some reactions release energy and others absorb energy.
9-12	PS1.B: Chemical reactions	Chemical processes are understood in terms of collisions of molecules, rearrangement of atoms, and changes in energy as determined by properties of elements involved.
