There are many fields or topics of science. Each can be catalogued into 1 of 3 branches: Three Branches of Science Examples Physical Life Earth 8th Grade Science Curriculum Topics Branch of Science 8.P.1.1 – Elements, Compounds, & Mixtures 8.P.1.2 – Properties of Matter & The Periodic Table 8.P.1.3 – Physical Changes versus Chemical Changes 8.P.1.4 – Chemical Equations and the Law of Conservation of Mass 8.P.2.1 – Environmental Impacts for Managing Energy Resources 8.P.2.2 – Renewable versus Nonrenewable Resources 8.E.1.1 – Earth’s Hydrosphere (Local to Global) 8.E.1.2 – Marine Environment, Ecosystems, and Technology 8.E.1.3 – Physical, chemical, and Biological Affects on the Hydrosphere 8.E.1.4 – Water quality treatment and monitoring 8.E.2.1 – Rock and fossil evidence supporting Earth’s age 8.E.2.2 – Rock and fossil evidence supporting Earth’s history 8.L.1.1 – Microbes and Disease 8.L.1.2 – Epidemic versus Pandemic 8.L.2.1 – Exploring Biotechnology 8.L.3.1 – Abiotic verses Biotic Components of an Ecosystem 8.L.3.2 – Interactions among Relationships within an Ecosystem 8.L.3.3 – Biogeochemical Cycles and Food Webs 8.L.4.1 – Classification Systems and the Theory of Evolution 8.L.4.2 – Genetic Variations and Adaptation 8.L.5.1 – Molecular biology - converting food to energy 8.L.5.2 – Lifestyle (diet and exercise) effects on the body The Nature of Science: What Makes it Science?
