Unit+Plan

Unit Plan: ** Periodicity and Electron Configuration ** ** Introduction: ** This lesson is designed to give chemistry students a strong knowledge of electrons, their configuration, and the role of electrons in determining the distinctive characteristics individual elements possess.

** Analyze Learners: ** The audience for this lesson is general chemistry students. This is a required course for graduation. The students in this course range from sophomores to seniors. The pre requisites for the course are algebra and physical science. There is a range of ability levels in this course.

** State Objectives: **

· SC.O.C.1.5 - draw conclusions from a variety of data sources to analyze and interpret systems and models (e.g., use graphs and equations to measure and apply variables such as rate and scale, evaluate changes in trends and cycles, or predict the influence of external variances such as potential sources of error, or interpret maps). · SC.O.C.2.1 - classify pure substances by their chemical and physical properties. · SC.O.C.2.3 - describe atoms using the Quantum Model. · SC.O.C.2.4 - produce electron configurations and orbital diagrams for any element on the periodic table and predict the chemical properties of the element from the electron configuration. · SC.O.C.2.5 - illustrate Lewis’ dot structures for representative (main group) elements. · SC.O.C.2.7 - analyze periodic trends in atomic size, ionic size, electronegativity, ionization energy and electron affinity.

** Select Media and Material: ** Modern Chemistry Book, Smart Board, Computer with internet access, Handouts, Butcher paper or Post It poster paper. **Media/Websites:** Students and Instructor [|www.explorelearning.com] – Corresponding activity [] - Corresponding activity

** Utilize Media and Materials: ** The unit will be taught using a variety of instructional strategies. Students will have teacher centered lecture and note taking, they will have student centered activities involving critical thinking, and group activities involving presentations. The unit will take approximately nine days or nine blocks to complete. Each block class is equivalent to two class periods. One week of block is equivalent to two weeks of periods. On day one students will explore electron configuration by using the kaffee website and an accompanying guide/worksheet. This activity will introduce vocabulary and concepts associated with the location and behavior of electrons. On day two students will take notes on a power point presentation concerning quantum numbers and electron configuration and complete the electron configuration handout. On day three students will be involved in an activity on the explore learning website going through a gizmo simulation on electron configuration and the relation with atomic radii. On day four students will practice their knowledge of electron configuration using a smart board activity. On day five students will take part in the Mendeleev periodic table activity. They will be organizing unknown elements according to their physical and chemical characteristics. After they have organized and identified the elements properly they will analyze trends in the properties and summarize their findings in a paper. On day six students will graph some of the data from the Mendeleev assignment and their book using excel and further analyze specific trends in the periods and groups of the periodic table. The trends they will analyze are atomic radii, ionization energy, electronegativity, and electron affinity. On day seven they are to use their knowledge of trends to complete an activity where there are gaps/unknowns in information and they have to predict the values of the unknown by evaluating their graphs correlating that with their knowledge of trends. Also on day seven the students will take notes on a prezi including podcasts on the topics of atomic radii, ionization energy, electronegativity, and electron affinity. On day eight in groups they will create presentations on post it paper of an assigned trend. Also on day eight they will be given reviews to study for their exam. On day nine they will take their exam.

** Required Learner Participation: ** Student engagement will be achieved by using various teaching strategies, assessments, group hands on activities, and computer programs. Switching up the methods used to relay information helps with student attention and helps to keep them more on task. Using different types of assessment aides in keeping the students interested in the topics. Using assignments such as the Mendeleev assignment which uses hands on organization of cards increases student involvement. Because current students are digital natives and are very tech savvy the use of computer activities and simulations keep a student’s attention and focus on the topic. Using power points and prezis ,rather than continuous lecture and notes, also aides in student attention.

** Evaluate and Revise: ** Students are evaluated using a variety of sources. They will have to analyze and create graphs from information; they will be completing computer activities and print materials. They will do a group presentation and they will have a traditional test.
