YOUNGSTOWN CITY SCHOOLS SCIENCE: CHEMISTRY UNIT #3 “THE PERIODIC TABLE” UNIT PLAN (2 Weeks) 2013-2014 SYNOPSIS: A focus on the contributions of individuals in the development of the periodic table. The student will recognize the periodic trends and properties of the elements on the periodic table and use these characteristics to identify elements. The students will learn how to write the electron configuration and orbital fill-in diagrams for elements. Students will create a video podcast about the periodic table. ENABLERS: Mendeleev’s periodic law, Modern day periodic law, Law of Octaves, Families of the periodic table, oxidation state, ground state, excited state, average atomic mass, electron configuration, orbital fill-in diagram, atomic radii, electronegativity, ionization energy, metalloids, semi-metals, periodic trends STANDARDS III. HISTORY OF THE PERIODIC TABLE A. Elements are arranged in order of increasing atomic number on the periodic table such that elements with similar properties are placed in the same column 1. Recognize the contributions of individuals in the development of the periodic table 2. Demonstrate understanding that when elements are listed in order according to atomic number, repeating patterns of physical and chemical properties identify families of elements with similar properties 3. The periodic table is a consequence of the repeating patterns of outermost electrons B. Periodic trends and arrangements of elements 1. Alkali metals 2. Alkaline earth metals 3. Transition metals 4. Boron family 5. Carbon family 6. Chalcogens 7. Halogens 8. Noble gases 9. Lanthanide series 10. Actinide series C. Similarities in the configuration of valence electrons for a particular group can be predicted 1. Electron configuration can be written from the position on the periodic table 2. Repeating patterns in electron configurations explain many of the trends in the properties observed. D. Atomic theory and bonding must be used to explain trends in properties across periods or down columns including atomic radii, ionic radii, first ionization energies, electronegativities, and whether the element is a solid or a gas at room temperature LITERACY STANDARDS RST 9: Synthesize information from a range of sources (e.g., texts, experiments, simulations) into a coherent understanding of a process, phenomenon, or concept, resolving conflicting information when possible. (with Periodic Law) TEACHER NOTES MOTIVATION 1. Students will perform the Start-Up Activity “What is a Periodic Table?” on page 115 of the Holt Chemistry textbook. Students will sit in assigned desks according to Teacher’s seating chart (designed before class based on students’ names and birthdates). On a blank chart, students will write down information about themselves such as names, dates of birth, hair color, and height in the spaces that represents where they are seated. Students will question each other around them, writing the information down in the blank seating charts. Students will analyze the information gathered and explain identified patterns used to create the chart. 07/12/2013 1 Chemistry Unit 3 – The Periodic Table YCS Science 2013-2014 TEACHER NOTES MOTIVATION 2. Teacher shows samples of student-produced video podcasts about the periodic table: a. http://www.youtube.com/watch?v=k5aLPkgOswU&feature=related (“The Periodic Table”) b. http://www.youtube.com/watch?v=Apr7MdbHGQo&feature=related (“The Chemistry Rap”) c. http://www.youtube.com/watch?v=OduTDUGeAXE&feature=related (“The Element Song”) 3. Teacher shows video “The Periodic Table” from United Streaming: http://player.discoveryeducation.com/?guidAssetId=737ea745-d8fe-4bb1-8e95b22a27d2b7de 4. Students set personal and academic goals 5. Preview the Authentic Assessment so students know what is expected by the end of the Unit TEACHER NOTES TEACHING-LEARNING 1. Teacher discusses the history of the periodic table (John Newlands, Dmitri Mendeleev, and Henry Moseley) and the periodic law. Students will perform the Group Activity on page 120 TE of the Holt Chemistry textbook. {Students randomly choose cards numbered 1-36. They will research and write a descriptive paragraph about the element whose atomic number they drew. The class is divided into groups of three and given blank cards with 25 boxes in a 5x5” square to each group. Students fill the squares with any 25 of the 36 elements in any order. Teacher reads the student-made clues and allows each group of students to mark an X through each element they identify. The first group to correctly complete a vertical, horizontal, or diagonal row is the winner.} [IIIA] 2. Teacher discusses properties and characteristics of the families on the periodic table. This is an introduction to using properties to identify elements. Teacher performs demonstration “Orange-Yellow Light of Sodium” from Holt Chemistry textbook on page 125. Teacher performs demonstration “Reactivities of Mg and Ca” on page 126 TE. Students will observe a display of elements from each of the families. Students are to observe, take notes and focus on physical properties of the samples. [IIIA; IIIB] 3. Students will be divided into eight groups (or more depending on the number of students in the class; 13, 14, and 15 may be used if class size is larger, but these will not be included on the test) and assigned one chemical family to each group - - be sure to cover 1, 2, 16, 17, 18, lanthanides, actinides, transition elements. Students will use the textbook, the CRC handbook, the Merck Index, the Internet, and other references to determine six characteristic properties for their assigned group. Students will list each property on separate sheets of paper. The information will be collected by the Teacher who will mix up the students’ papers, and pass out an equal number of slips to each group. Students will place each property on the periodic table projected on the board with the correct group number and explain the thinking behind their choices. Class will hold discussion about why things are placed where they are and justify their reasoning. [III.B.1 and 10, IIIC, IIID] 4. Teacher discusses periodic trends on the periodic table: ionization energy, atomic radii, electronegativity, ionic radii, electron affinity, melting and boiling point. Teacher performs demonstration “Size of an Oleic Acid Molecule” on page 135 of Holt TE Chemistry textbook. Students take notes and they will construct a graphic organizer (foldable) to compare and contrast the periodic table trends. [IIIC.1; IIIC.2] 5. Teacher reviews writing electron configurations using the periodic table. Students take notes 07/12/2013 2 Chemistry Unit 3 – The Periodic Table YCS Science 2013-2014 TEACHER NOTES TEACHING-LEARNING and ask questions. Students will identify elements with a flame test, write electron configurations, and graph atomic diameters from atomic numbers to interpret trends in the periodic table by performing the either the Lab “Electron Configuration and Periodic Properties (Traci)” or the “Flame Test Lab (Tim) [IIIC.1; IIIC.2; IIID] 6. Students will perform the Lab “The Periodic Law.” [IIIB; IIIC] TEACHER NOTES TRADITIONAL ASSESSMENT 1. Unit Test: Multiple-Choice TEACHER NOTES TEACHER CLASASROOM ASSESSMENT 1.
