1 Lesson Plan This lesson plan depicts a hands-on, minds-on activity and worksheet involving knowledge students have gained about atoms, valence electrons, and energy levels. Students use this knowledge to construct their own modified periodic table and to recognize patterns in atomic structure across the periodic table. This lesson must be taught after students are familiar with atoms, their structure, atomic models, valence electrons, and energy levels. Students will proceed to learn about periodic families and their unique characteristics after this lesson is complete. In this lesson students are asked to use their prior knowledge to design their own periodic table and describe patterns they see across the periodic table. This lesson promotes ISTE NET-S Standard 1 (a) by helping to facilitate creative thinking, innovation, and inventiveness. InTASC Standard 1 (b) requires that teachers create developmentally appropriate curriculum that takes into account the needs of their students. I have sought to do so in this lesson by scaffolding prior knowledge that will be required for this lesson, and choosing a lesson that is both challenging, and doable. This lesson shows that I am able to comply with InTASC Standard 7 (b-d), which promotes the development of appropriate teaching strategies, summative and formative assessments, and activities that activate prior knowledge.

2 Rachel Ann MacAdam TTE 536 / December 3, 2013 Lesson Title: Periodic Table Basics Terminal Objective: Using a periodic table of their own creation students will be able to write two paragraphs describing at least three patterns in atomic structure across the periodic table of elements. Content Standard: 8 th Grade General Science Arizona Science Standards Strand 5: Physical Science Concept 1: Properties and Changes of Properties in Matter--Understand physical and chemical properties of matter. PO 6. Explain the systematic organization of the periodic table Next Generation Science Standards MS-PS1-1. Develop models to describe the atomic composition of simple molecules and extended structures. Language Standard: Arizona English Language Proficiency Standards ELL: IV-LI-8 writing multiple paragraphs of persuasive text which state a clear position and relevant evidence. Time 10min 15min Task Analysis (Sub-Objectives w/ Bloom) SWBAT list and diagram the basic properties of an oxygen atom. Bloom s Level: Application SWBAT list and diagram the basic properties of 18 elements on the periodic table of elements. Teaching Strategies Bell Work: find Oxygen on the Periodic Table. Write down if it is a gas, solid, or liquid at room temperature, how many protons, neutrons, and electrons it has, create a Bohr diagram, and a Lewis Structure. Periodic Table Basics Worksheet: for the 18 elements provided on the worksheet students determine the element s basic atomic properties and structure. Active Student Participation (Check for Understanding) On a separate piece of paper students will complete the bell work. This will be turned into the teacher at the end of the class period. Students individually write pertinent information about 18 separate elements on their element cards using their text book and notes as a reference.

3 10min 10min 5min Bloom s Level: Application SWBAT create their own periodic table of elements. Bloom s Level: Comprehension SWBAT explain elemental properties and patterns within the periodic table. Bloom s Level: Analysis Using a periodic table of their own creation students will be able to generate two paragraphs describing at least three patterns in atomic structure across the periodic table of elements. Bloom s Level: Synthesis Create a basic periodic table: students color code and place each element in their correct order, then glue the elements down to form their own periodic table. Periodic Table Worksheet: students complete this individually or with a desk partner. PPT aide: a power point will be on the board for students to follow along as they complete each step of the worksheet. Q & A with slates: after students have completed their work individually we will review each step through the use of question and answer involving slates. Closure: on the same page as the Bell Work students describe in two paragraphs at least three patterns in atomic structure across the periodic table. Students create a periodic table using their element cards and butcher paper. Each student completes their own worksheet regarding the periodic table and atomic properties across the periodic table. They may work alone or with their desk partner, but will need to complete their own worksheet. After individuals have had a chance to complete their own work we will check for understanding with slates and class Q & A. Using what they have learned throughout class students describe the patterns they notice in atomic structure as we move across the periodic table. They will write at least three patterns they observe. This will be collected at the end of class.
