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) [[image:http://www.openarchives.org/ore/0.1/atom-images/Model2Atom.jpg caption="http://www.openarchives.org/ore/0.1/atom-images/Model2Atom.jpg"]]What is an element?An element is a substance that is made entirely from one type of atom(http://education.jlab.org/qa/element.html
 * 2) What are elements made of?atoms join together to form molecules, which in turn form most of the objects around you.[[image:http://education.jlab.org/qa/atom_model_04.gif caption="http://education.jlab.org/qa/atom_model_04.gif"]]
 * 3) How are elements different from each other?The difference between one element and another stems from the number of protons and electrons in each atom. Each element has its own unique number of protons and electrons per atom eg Hydrogen atoms have 1 proton and 1 electron, Helium 2, Lithium 3 and so on.(http://wiki.answers.com/Q/Explain_why_elements_are_different_from_each_other)
 * 4) How many different elements are there? 117 different elements(http://education.jlab.org/qa/element.html)
 * 5) In terms of chemistry--what is a property?are the things that distinguish the difference between matters(http://wiki.answers.com/Q/What_is_the_meaning_of_%27property%27_in_science_terms)
 * 6) How are elements on the periodic table grouped? Why?One reason the periodic table of the elements is so useful is because it is a means of arranging elements according to their similar properties.they are use full animals
 * 7) What are the vertical columns and the horizontal rows called on the periodic table? What are their significance?They are called groups or families .And the might even have similar chemistry activity
 * 8) What are the features of the periodic table? (How do you read it?atoms minerals. Left side is more reactive while the right side really not

=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.
