The basic steps are: observation, hypothesis, experimentation, and conclusion.<\/li>\n<li>Data is the information collected during an experiment. Precise and accurate data should be used and reported. Accuracy is a description of how close a measurement is to the true value of the quantity measured. Precision is the exactness of a measurement.<\/li>\n<li>Many scientists use graphs and charts to showcase data. The most commonly used charts or graphs are line graphs, bar graphs, and pie charts.<\/li>\n<li>Scientific notation takes the form of M\u00d710<sup>n<\/sup> where 1 \u2264 M &lt; 10 and n represents the number of decimal places to be moved. Positive n indicates the standard form is a large number. Negative n indicates a number between zero and one.<\/li>\n<li>A significant figure is a prescribed decimal place that determines the amount of rounding off to be done based on the precision of a measurement.<\/li>\n<li>Mean is the arithmetic average of a list of numbers. It is found by adding all the numbers in the list and dividing by the number of elements in the list.<\/li>\n<li>Median is generally the middle element in a list of numbers, found by ordering them from least to greatest.<\/li>\n<li>Mode is the number that occurs most often in a list of numbers.<\/li>\n<li>It is important to know basic lab safety and to convey this to our students.<\/li>\n<li>Different tools are used for many different experiments in a science laboratory. Meters are used to take precise readings of experiments conducted.<\/li>\n<li>Matter is made up of elements which are made up of atoms.<\/li>\n<li>Atoms with a charge, either positive or negative are called ions. Atoms combine to form molecules.<\/li>\n<li>Elements are the simplest substances on earth. Just like atoms, elements combine to form compounds and mixtures.<\/li>\n<li>The two main types of compounds are ionic and molecular compounds.\n<ul>\n<li>Ionic compounds are compounds composed of cations and anions combined to have a neutral net charge.<\/li>\n<li>Molecular compounds are substances consisting of atoms that are covalently bonded.<\/li>\n<\/ul>\n<\/li>\n<li>Mixtures are a combination of more than one pure substance. A pure substance is any matter that has a fixed composition and definite properties.\n<ul>\n<li>Heterogeneous mixtures are mixtures that are not uniformly distributed.<\/li>\n<li>Homogeneous mixtures are uniformly distributed.<\/li>\n<\/ul>\n<\/li>\n<li>There are three main states of matter: solid, liquid, and gas.\n<ul>\n<li>Solids have a rigid volume and vibrate about a fixed position.<\/li>\n<li>Liquids flow more freely than solids and their volume will assume the shape of the container they are placed into.<\/li>\n<li>Gases are very free flowing and have the most energy of the three states.<\/li>\n<\/ul>\n<\/li>\n<li>Newton\u2019s First Law states that an object at rest remains at rest and an object in motion maintains its velocity unless either object experiences an unbalanced force.<\/li>\n<li>Newton\u2019s Second Law states the unbalanced force acting on an object equals the object\u2019s mass times its acceleration. (<em>F = ma<\/em>)<\/li>\n<li>The electromagnetic spectrum is the full range of light at different frequencies and wavelengths. The electromagnetic spectrum consists of radio waves, microwaves, infrared waves, visible light, ultraviolet light, x-rays, and gamma rays.<\/li>\n<li>DNA contains the genetic instructions specifying the biological development of all cellular forms of life and consists of the repeating nucleotides thymine, adenine, guanine and cytosine.<\/li>\n<li>RNA serves as the template for translation of genes into proteins.<\/li>\n<\/ul>\n<table border=\"2\" width=\"100%\" cellpadding=\"7\" align=\"center\">\n<tbody>\n<tr>\n<td>\n<div align=\"center\"><span class=\"teachertip\"><strong>Don&#8217;t forget to take the <a href=\"http:\/\/www.abcte.org\/drupal\/courses\/crc\/quizzes\/sciknowledge\" target=\"popsome\">Scientific Knowledge Chapter Quiz.<\/a><br \/>\nTo take the quiz, click on the Quizzes link on the left-hand navigation bar.<\/strong><\/span><\/div>\n<\/td>\n<\/tr>\n<\/tbody>\n<\/table>\n<p><!-- CONTENT ENDS HERE --><\/p>\n<p><!-- UPDATE NEXT\/PREVIOUS BELOW --><\/p>\n<div class=\"advance\">\n<p><a class=\"button button-primary\" href=\"http:\/\/americanboard.org\/Subjects\/chemistry\/general-science-knowledge-ii\">\u2b05 Previous Lesson<\/a>\u00a0<a class=\"button\" href=\"http:\/\/americanboard.org\/Subjects\/chemistry\/scientific-knowledge\">Workshop Index<\/a>\u00a0<a class=\"button button-primary\" href=\"http:\/\/americanboard.org\/Subjects\/chemistry\/atomic-structure-periodicity-and-matter\">Next Workshop \u27a1<\/a><\/p>\n<\/div>\n<p><a class=\"backtotop\" href=\"#title\">Back to Top<\/a><\/p>\n<\/div>\n","protected":false},"excerpt":{"rendered":"<p>\u2b05 Previous Lesson\u00a0Workshop Index\u00a0Next Workshop \u27a1 Review Science is a system of knowledge based on facts or principles.
