  2. VISUALIZATION CLASSZONE.COM Watch how a radioactive element decays over time. 7.3 The periodic table is a map of the elements. The periodic table has distinct regions. reactive metal nonmetal metalloid radioactivity half-life Three regions are metals, metalloids, and nonmetals. CHAPTER RESOURCES SECTION OUTLINE

  3. 7.2 Elements make up the periodic table. Elements can be organized by similarities. atomic mass Groups of elements have similar properties. periodic table Elements in a period have varying properties. group period CHAPTER RESOURCES SECTION OUTLINE

  4. proton nucleus neutron SIMULATION electron cloud CLASSZONE.COM Build a model of an atom. 7.1 Atoms are the smallest form of elements. All matter is made of the atoms of approximately 100 elements. proton Atoms of elements contain protons, neutron neutrons, and electrons. nucleus electron atomic number atomic mass number isotope ion CHAPTER RESOURCES SECTION OUTLINE

  6. VISUALIZATION View examples of endothermic and exothermic reactions. 9.3 Chemical reactions involve energy changes. • Different bonds contain different amounts of energy. • In an exothermic reaction, more energy is released than added. bond energy exothermic reaction • In an endothermic reaction, more energy is added than released. endothermic reaction photosynthesis CHAPTER RESOURCES SECTION OUTLINE

  8. Carbohydrates Lipids Proteins Nucleic Acids • sugars and starches • energy for cells • plant cell walls • strings of amino acids • used for structure, transport, immune system, enzymes • fats and oils • energy for cells • cell membranes • DNA and RNA • genetic code • code for amino acids 11.3 Carbon-based molecules are life’s building blocks. There are four main types of carbon-based molecules in living things. carbohydrate lipid protein enzyme nucleic acid CHAPTER RESOURCES SECTION OUTLINE

  9. VISUALIZATION CLASSZONE.COM Observe and rotate three-dimensional models of carbon-based molecules. 11.2 Carbon-based molecules have many structures. and rings. Carbon can form chains organic compound inorganic compound polymer isomer CHAPTER RESOURCES SECTION OUTLINE

  11. VISUALIZATON VISUALIZATION Examine how electrons move in a polar covalent molecule. CLASSZONE.COM Watch an animation showing ionic and covalent bonding. 8.2 Chemical bonds hold compounds together. • Chemical bonds between atoms involve electrons. ionic bond • Atoms can transfer electrons. covalent bond • Atoms can share electrons. • Chemical bonds give all materials their structure. molecule polar covalent bond CHAPTER RESOURCES SECTION OUTLINE

  12. VISUALIZATION CLASSZONE.COM Find out how sunlight affects the temperature in different places at different times of year. 12.2 Earth rotates on a tilted axis and orbits the Sun. Earth’s rotation in sunlight causes day and night. The changing angles of sunlight on Earth cause seasons. axis of rotation revolution season equinox solstice CHAPTER RESOURCES SECTION OUTLINE

  13. VISUALIZATION Learn how your motion makes a difference in what you observe. 1.1 An object in motion changes position. position Position is measured from a reference point. reference point Motion is measured relative to an observer. motion CHAPTER RESOURCES SECTION OUTLINE

  14. SIMULATION Change the sizes and directions of forces on an object and predict how it will move. 2.1 Forces change motion. Newton's first law Objects at rest remain at rest, and objects in motion remain in motion with the same velocity, unless acted upon by an unbalanced force. force net force Newton's first law inertia CHAPTER RESOURCES SECTION OUTLINE

  15. 2.2 Force and mass determine acceleration. Newton's second law The acceleration of an object increases with increased force and decreases with increased mass, and is in the same direction as the force. Newton's second law centripetal force SIMULATION Explore Newton’s second law. CHAPTER RESOURCES SECTION OUTLINE

  21. VISUALIZATION Explore how temperature affects the speed of particles. 6.2 Temperature depends on particle movement. • All particles in matter have kinetic energy. • Temperature is the measurement of the average kinetic energy of particles in an object. kinetic theory of matter • Temperature is commonly measured on the Fahrenheit or Celsius scales. temperature thermometer • Particles in a warmer substance have a greater average kinetic energy than particles in a cooler substance.
