8.1.4 Obtain and evaluate information to describe how synthetic materialscome from natural resources, what their functions are, and how society uses these new materials.
8.1.5 Develop a model that uses computational thinking to illustrate causeand effect relationships in particle motion, temperature, density, and state of a pure substance when heat energy is added or removed.
8.3.3 Ask questions to obtain, evaluate, and communicate informationabout how changes to an ecosystem affect the stability of cycling matter and the flow of energy among living and nonliving parts of an ecosystem.
8.4 Interactions with Natural Systems and Resources
8.4.1 Construct a scientific explanation based on evidence that shows that the uneven distribution of Earth's mineral, energy, and groundwater resources is caused by geological processes.
8.4.2 Engage in argument supported by evidence about the effect of per-capita consumption of natural resources on Earth's systems.
