Do you lose stuff in your bedroom? Have you spent countless hours looking for that lost sock or that missing piece of Ms. Johnson's homework? If so, then you need ORGANIZATION! Science is all about organization. Your Mastery Assessment is to create an an infomercial with the purpose of selling the periodic table to a group of very unorganized scientists.

=What should you know?= > > > >
 * 1) What is an element? **A pure substance that cannot be broken down into other substances by chemical or physical means.**
 * 2) What are elements made of? **It’s made from a single proton and a single electron. __http://education.jlab.org/qa/element.html__ **
 * 3) How are elements different from each other? **The difference between elements stems from their atomic structure.**
 * 1) How many different elements are there? **There are 117 different elements.**
 * 2) In terms of chemistry--what is a property? **A chemical property is any of a material's properties that becomes evident during a chemical reaction; that is, any quality that can be established only by changing a substance's chemical identity.**
 * 1) How are elements on the periodic table grouped? Why? **Elements in the periodic table are arranged in order of increasing atomic number (which is just the number of protons found in the nucleus of that element).**
 * 1) What are the vertical columns and the horizontal rows called on the periodic table? What are their significance? **They are called groups or families. Often the elements that are found in the same group as each other have similar chemistry and reactivity.**
 * 1) What are the features of the periodic table? (How do you read it?) **Used today, the properties of the elements repeat in each period -or row-of the table . Periodic means “in a regular, repeated pattern.”**

=Mastery Assessment= //Deadline: 3/2/2010// Science Rocks, Inc. has hired you for a marketing assignment. You and your team have been tasked with creating an infomercial with the purpose of selling the periodic table to a group of unorganized scientists. They see nothing wrong with the way they keep their elements "organized" so you must point out every feature of the periodic table to prove to them they //need// this tool.
