4. Practice:  Chemistry is the study of matter, its properties and its changes.  Every kind of matter has a set of properties that help identify matter.

5.  Some properties are easily observable, such as color, shape, odor, and texture.  Other properties, such as mass, volume and temperature can be measured using tools.

6.  Some properties cannot be observed or measured directly; instead must be calculated.  Density is one of those properties.

7.  The building blocks of matter are known as elements.  An element is the simplest pure substance made of only one kind of atom and has definite properties.

8.  Over the centuries, scientists have worked to organize all the known elements into a specialized chart called the Periodic Table Of Elements.

9.  Chemical symbols are used to represent each element. Writing Chemical Symbols  The symbol always begins with a capital letter.  If there is a second or third letter, it is written in lower case.  Periods are not used at the end of the symbol.

10. Application: Pick 7 random cards and complete the data table. ElementSymbolPhysical property 1. 2. 3. 4. 5. 6. 7

11. Connection: Objective: Arrange elements into groups and describe the property used for sequencing the cards. Procedure: 1.Place the element cards out on the desk. 2.Classify the elements into groups using the information provided on each card. 3.label (name) each group in your spiral and write the symbols of each member of the group. 4.Visit other groups to see how they grouped the cards.

12. Connection: label (name) each group in your spiral and write the symbols of each member of the group. Group _____________ Symbols of members __ Group _____________ Symbols of members __ Group _____________ Symbols of members __

13. Exit: 1.Describe the reasoning you used to arrange the cards. 2.How did you decide on a name for the groups? 3. How did your arrangement differ from other groups’ arrangement? 4. If you discovered an unknown element, how would the element’s physical properties allow you to determine position of the element in your arrangement?
