8.1.2: Understand that elements are organized on the periodic table based on atomic number.
8.1.7: Explain that chemical changes occur when substances react and form one or more different products, whose physical and chemical properties are different from those of the reactants.
8.1.8: Demonstrate that in a chemical change the total numbers of each kind of atom in the product are the same as in the reactants and that the total mass of the reacting system is conserved.
8.2.2: Describe and model how water moves through the earthÂ?s crust, atmosphere and oceans in a cyclic way as a liquid vapor and solid.
8.2.6: Identify, explain and discuss some effects human activities (e.g., air, soil, light, noise and water pollution) have on the biosphere.
8.2.8: Explain that human activities, beginning with the earliest herding and agricultural activities, have drastically changed the environment and have affected the capacity of the environment to support native species. Explain current efforts to reduce and eliminate these impacts and encourage sustainability.
8.3.1: Explain that reproduction is essential for the continuation of every species and is the mechanism by which all organisms transmit genetic information.
8.3.2: Compare and contrast the transmission of genetic information in sexual and asexual reproduction.
8.3.3: Explain that genetic information is transmitted from parents to offspring mostly by chromosomes.
8.3.4: Understand the relationship between deoxyribonucleic acid (DNA), genes and chromosomes.
8.3.5: Identify and describe the difference between inherited traits and the physical and behavioral traits that are acquired or learned.
8.3.6: Observe anatomical structures of a variety of organisms and describe their similarities and differences. Use the data collected to organize the organisms into groups and predict their relatedness.
8.3.7: Recognize and explain that small genetic differences between parents and offspring can accumulate in successive generations so that descendants may be different from their ancestors.
8.3.8: Examine traits of individuals within a population of organisms that may give them an advantage in survival and reproduction in given environments or when the environments change.
8.3.10: Recognize and describe how new varieties of organisms have come about from selective breeding.
