Grade: Grade 11-12
Topic: Chemistry – Intro. to the Periodic Table of the Elements
Content: Investigation of the Periodic Table – its organization and the characteristics of the elements in the nine groups listed. California State Content Standards for Chemistry 1a-f (Atomic and Molecular Structure). ISTE Standards: Routinely and efficiently use online information resources to meet needs for collaboration and research. Collaborate with peers to contribute to a content-related knowledge base by using technology to compile, synthesize, produce and disseminate information.
Goals: Students will be able to describe the physical properties
and practical use information about one of the following Element Groups: Alkali Metals, Alkaline Earth Metals, Transition Metals, Other Metals, Metalloids, Non-Metals, Halogens, Noble Gases, and Rare Earth Elements. Students will be able to use internet resources and presentation software (PowerPoint) to summarize and present key information.
Objectives: Given one of nine Element Groups from the Periodic Table, students will use website resources to work collaboratively in groups of 2-3 to prepare a 3 slide PowerPoint presentation. These lessons will require two 50 minute class periods to complete.
Materials: Computer Lab with internet access and PowerPoint software, Periodic Table of the Elements, Website resources, Rubric designed by teacher.
Introduction: At prior class meeting introduce Periodic table and its organization. Describe lesson for next time (10 minutes). Assign reading on this topic for homework. Meet in Computer lab on day of lesson.
Development: Describe assignment. Students work in groups to investigate their assigned element group online (www.chemicalelements.com). Each group is to list the elements in their assigned group and the atomic number range (slide 1); the physical characteristics of their group, including reactivity (electrons in outer shell) and natural physical state (slide 2); and at least 3 unique characteristics of their element group, including some practical uses for their elements (slide 3). (5-10 minutes)
Practice: Students begin research, synthesize and summarize information using PowerPoint. When complete, students print out notes copies to turn in to teacher. Presentations will be at the beginning of the next class period.(40 minutes)
Accommodations: Students who have difficulty with this assignment will be assisted by a teacher aid or volunteer. The teacher will rotate around the room to keep the students on task and assist where needed.
Checking For Understanding: Students present PowerPoint slides to class. All students will take notes. Use a Rubric to evaluate student performance. Nine presentations, 5 minutes each (45 minutes). This will assist the students with direction and expectations.
Closure: Review information, highlighting everyday uses of elements and organization of the Periodic Table. (5 minutes)
Evaluation: The student presentations will be assessed by the rubric. Students’ use of oral presentation skills will also be assessed.
Teacher Reflections: Did the students have enough time to complete this assignment? Will I have to extend this lesson? Was the object reached and did the students find value in this experience?
