| Patricia Barker CSP Summer 2001 Lesson Plans July 26, 2001 (A) CSP Lesson / Major Concepts: Workshop Addressed-July 9/10: Internet-based Periodic Tables and Periodic Trends Relevant Websites-http://www.csun.edu/~vceed002/csp/period_table/periodic_table.html http://www.chemcenter.org/classroom_0521.html http://www.chemistrycoach.com/periodic_tables.htm#Periodic%20Tables http://pearl1.lanl.gov/periodic/ http://www.chemicalelements.com/ http://www.sing-smart.com/ (B) Objectives: Content Standards Addressed- Chemistry Atomic and Molecular Structure 1. The periodic table displays the elements in increasing atomic number and shows how periodicity of the physical and chemical properties of the elements relates to atomic structure. As a basis for understanding this concept: a. Students know how to relate the position of an element in the periodic table to its atomic number and atomic mass. b. Students know how to use the periodic table to identify metals, semimetals, nonmetals, and halogens. c. Students know how to use the periodic table to identify alkali metals, alkaline earth metals and transition metals, trends in ionization energy, electronegativity, and the relative sizes of ions and atoms. d. Students know how to use the periodic table to determine the number of electrons available for bonding. g. * Students know how to relate the position of an element in the periodic table to its quantum electron configuration and to its reactivity with other elements in the table. i. * Students know the experimental basis for the development of the quantum theory of atomic structure and the historical importance of the Bohr model of the atom. (C ) Materials and Equipment: Period Tables for each student, Paint color chips from local hardware store, Period Table Handouts, a computer with Internet access, CD-Rom, Video, Materials for Bohr model (enough for the number of subatomic particles), Periodic Table (blank) with element cards (Velcro), Period Table block game from Flinn Scientific, Music CD of Holy Molee by Lynda Jones. (D) Outline of Lesson (3days to a week) (1) Dispatch / Warm-up: Students will work in groups of 2-4 depending on overall class size on putting paint chips in logical groupings. The students will be asked to share their reasoning as to why they chose the categories in which they placed their colored chips. If the Internet is available, some students will do the Internet version developed by Norm Herr of CSUN. The next days’ warm-ups will come from the aforementioned websites and games dealing with the Periodic Table and Trends. Students will also be practicing Holy Molee songs. (2) Introduction: During the first few days of school, my students are to randomly pick out a card out of a box. These cards have symbols of the elements from the Periodic Table. In lecture the students will learn about how groups within the Table have similar properties (just like members of a family) and will be placed into work pods once their chemical families are established. The dynamics of the remainder of the lessons in this unit are based upon this chemical family pod work group. (3) Lecture/discussion (a) Lecture notes: Discussion of families: names, similarities, sizes. Transfer family concept to format of Periodic Table. Then discussion of what families have in common like valence numbers. (b) Diagrams & photos: Overhead transparencies, CD-Rom, Video, and Internet Tables will provide visual aids. (c) Handouts: Periodic Tables (wallet size also available for the devout student), Puzzles on the periodic table and trends like electronegativity, radii, electron affinity, etc.: all taken from a workbook on the Periodic Table. Information on determining number of electrons in each shell, valence numbers, and predicting properties are made available. (4) Activities (a) Group work: Internet Periodic Table exploration about the Element they have randomly chosen, Building a Bohr Model using materials from home (enough for the subatomic particles). Examples may include beads, pins, balls, paper cut-outs and the like. (b) Videos-The Periodic Table (c ) CD-Rom on the Periodic Table (d) CD Musical of The Periodic Table (5) Summary (a) Quiz-Electron Conf. And Periodic Trends (G) Homework Heath Chemistry Chapter 11--Periodic Table and Chapter 12--Elements Building a Bohr Model project/Presenation in Chemical Families Students will also need to come up with songs to enter National Science Songwriters Contest. |
