Basic Scientific Concepts Organic vs. Inorganic: The primary difference between organic compounds and inorganic compounds is that organic compounds always contain carbon while most inorganic compounds do not. Also, all organic compounds contain carbon, hydrogen or C-H bonds. Ex. of Organic Compounds: Nucleic Acids, Fats, Sugars, Proteins, Enzymes, Fuels, DNA, and Methane CH4 Ex. of Inorganic Compounds: Salts, Metals, Table Salt and Carbon Dioxide Gene: A unit of heredity; a segment of DNA nucleus of the cell that contains information for the synthesis of a specific protein. Ex: Enzymes Gene pool: Combined genetic information, such as alleles, of all the members of a particular population.

APES Mathematics Review The APES Examination will require you to do mathematical calculations. Occasionally these calculations may be somewhat esoteric, and you may find it possible to do them in your head; nonetheless, it is mandatory to show all work for all calculations on the free-response section of the APES exam. This worksheet is designed help to prepare you for the type of calculations you may encounter on this year?s APES exam. Use a separate piece of paper, and for each problem, show every step of your work, and indicate the cancellation of all units?No Calculators!! Scientific Notation?All APES students should be able to work comfortably with numbers in scientific notation. ? Place the following numbers into scientific notation. 1. one billion

SCIENCE, MATTER, ENERGY, AND SYSTEMS p.28-49 Core Case Study ? Carrying Out a Controlled Scientific Experiment o controlled experiment- a way in which scientists learn about how nature works is to conduct a controlled experiment o variables- factors that can change within a system or situation being studied o single-variable analysis- an experiment designed to isolate and study the effects of one variable at a time o experimental group- a chosen variable is changed in a known way o control group- the chosen variable is not changed 2-1 What Is Science p.29-35 ? Science Is a Search for Order in Nature o science- an endeavor to discover how nature works and to use that knowledge to make predictions

7.6 Metals, Nonmetals, and Metalloids The more an element exhibits the physical and chemical properties of metals, the greater its metallic character. Metals: Good conductor of heat and electricity. Malleable (can be pounded into thin sheets) and ductile (can be drawn into wires). Tend to have low ionization energies and therefore tend to form positive ions relatively easily. Are oxidized. Compounds of metals with nonmetals tend to be ionic substances (halides). Most metal oxides are basic. Metal oxide + water -> metal hydroxide Metal oxide + acid -> salt + water Nonmetals: Nonmetals vary greatly in appearances. Because of their electron affinities, nonmetals tend to gain electrons when they react with metals.

Chapter 2 Science, Systems, Matter, and Energy Chapter Overview Questions What is science, and what do scientists do? What are major components and behaviors of complex systems? What are the basic forms of matter, and what makes matter useful as a resource? What types of changes can matter undergo and what scientific law governs matter? Chapter Overview Questions (cont?d) What are the major forms of energy, and what makes energy useful as a resource? What are two scientific laws governing changes of energy from one form to another? How are the scientific laws governing changes of matter and energy from one form to another related to resource use, environmental degradation and sustainability? Updates Online
