Title Introduction to the Periodic Table

							Title: Introduction to the Periodic Table

Subject Area: Chemistry

Grade Level: 10th

Concept(s) Addressed:
      History of the Periodic Table
      Construction of the modern Periodic Table
      Development of Periodic Law
      Families and Periods

Knowledge Goal(s): Students will understand
     - Why elements are organized and the importance of organization
     - Development of Periodic Law
     - Elements in the same Family have similar properties

Performance Objective(s):
      - Students will be able to classify elements as metal, non-metal,
         semimetal(metalloid).
      - Students will be able to identify elements of a Family
      - Students will answer questions on a worksheet as they work through the
         computer based presentation

Curriculum Standard(s) Addressed:

Instructional Procedures:
This material was used during one class period. Estimated time for completion – half
hour. Students can work separately or in groups.

The materials are presented as a computer based lesson created in Macromedia Flash.
Has some interactivity/animations. A worksheet was used to keep students focused and
provide leading questions to get them thinking about the development of the Periodic
Table. Periodic Tables were provided to each student for completion of the questions.

Assessment Rubric:
No official rubric created for this lesson. Since it was an introductory lesson over the
Periodic Table, some previous misconceptions may still be there. The worksheet was
corrected and handed back, but points were assigned based on completion of the exercise.

Teacher Notes:
      - This material was used as an introductory lesson on the Periodic Table. It
         provided a great set-up for future detailed information and trends in the
         periodic table.
       -   Students can work separately or in groups, but I noticed as they worked in
           groups they sounded their ideas out loud to each other, and explained their
           reasonings for their worksheet responses.
       -   It is recommended that the teacher walk around as students complete the
           lesson so that questions can be answered.

Handouts for Students:
     - PeriodicTableIntroWS1.pdf
         (Worksheet version 1 goes with PTIntro.swf and contains questions requiring
         knowledge of electron configurations s,p,d,f, and ionic charge)

       -   PeriodicTableIntroWS2.pdf
           (Worksheet version 2 goes with PTIntro2.swf and does not contain electron
           configurations or ionic charge)
