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?= > www.WikiAnswers.com >
 * 1) What is an element? In chemistry, a part or aspect of something abstract: From Dictionary
 * 2) What are elements made of? an atomic structure: From Dictionary
 * 3) How are elements different from each other? The difference elements stem from their atomic structure: www.WikiAnswers.com
 * 4) How many different elements are there? The current standard table contains 117 elements:http://en.wikipedia.org/wiki/Periodic_table
 * 5) In terms of chemistry--what is a property? A characteristic of a sample of matter that is fixed by its state.: http://chemistry.about.com/od/chemistryglossary/a/propertydef.htm
 * 6) How are elements on the periodic table grouped? Why? The periodic table is arranged in groups and periods, because there are different types of elements.: Erick pages
 * 7) What are the vertical columns and the horizontal rows called on the periodic table? What are their significance? The horizontal lines are called "periods" and show how many "shells" each atom has./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?) 1.The are arranged by atomic. 2. Elements are grouped by sharing common properties. 3. The first is the element symbol. This is the letter or letters in the middle of the square. 4. The properties define them as metals, nonmetals and metalloids. 5. The elements in Group 1 are the alkali metals. They are the first column of the periodic table, labels Group 1A. 6. They are in the second column of the periodic table, labeled Group llA. 7. These are the transition metals. These metals are in the columns labeled lB thru VlllB. These groups are broken up into smaller groups. 8. These are mixed because the elements gradually transition from metal to nonmetal. 9. Some elements have some properties of metals, but not all properties of metals, these are called metalloids. 10. Most are brittle and dull in appearance. They are the far upper right side, above the zigzag. 11. Group 17 are the halogens. They are in the column labeled Group VII. Halogens are highly reactive. 12. Group 18 are the noble gases. They are in the column labeled Group VIIl. Noble gases are not reactive. 13. Hydrogen is a special element. It has properties of metals, but is a gas at room temperature. Hydrogen is labeled a nonmetal. http://www.ehow.com/how_4716922_read-periodic-table-elements.html

=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.
