Explain how temperature influences chemical changes. Mid-Term Review Identify physical properties of substances and explain they do not change regardless of the sample size. Correctly measure mass and volume of an object to calculate and describe density (D=M/V) Classify and compare specific substances based on their physical properties. Identify physical and chemical changes by describing physical and chemical properties of matter (Include Sublimation). Explain how temperature influences chemical changes. Explain how chemical changes follow the law of conservation of mass. Explain how pH of a substance is determined Classify acidic, basic, and neutral substances using a pH scale (Use Illustrations). Describe properties of pure substances and mixtures, including solutions, colloids, and suspensions. Classify pure substances (elements & compounds), mixtures, and solutions by their properties.

Mid-Term Review Describe and explain the process of photosynthesis and cellular respiration Describe the role light, carbon dioxide, water, and/or chlorophyll in photosynthesis and cellular respiration. Explain how living things obey the law of conservation of mass and energy. Describe how energy and matter are transferred in the carbon cycle. Construct a model of the carbon cycle to show how matter and energy are continuously transferred in the environment. Describe how that the atom is the smallest unit and label the subatomic particles Explain the reasons why elements are grouped/ arranged on the periodic table. Describe how elements combine in a multitude of ways to make up all living and non-living things. Describe the motion of particles in solids, liquids, and/or gases. Use a model to explain the motion of particles in a solid, liquid, and gas. Explain how to plan and carry out scientific investigations of various types, such as systematic observations or experiments, identify variables, collect and organize data, interpret data in charts, tables, and graphics, analyze information, make predictions, and defend conclusions.
