The lesson introduces students to the Periodic Table of Elements. Depending on grade level, teachers may require the memorization of all elements or the most common elements. The lesson includes the history and development of the Periodic Table as well. Students should have previously learned about atoms, molecules, and other basics of chemistry prior to the use of this lesson. Teachers should be aware of the numerous Periodic Tables available for no charge on several web sites, and to use them for the class and research
Sample Classroom Procedure / Teacher Instruction:
- Display several abbreviations for the elements of the Periodic Table. Ask students: What do the abbreviations mean to you? Where can they be found?
- Allow for responses and discussion. Ask students: What is the significance of the number 118?
- Allow for responses and then introduce the Periodic Table of Elements. Display a large Periodic Table and/or distribute a copy of the table to each student or each pair of students. Allow students time to review the chart, ask questions such as: What do you notice about the table, what elements do you recognize, etc. Students should become familiar with the layout of the Periodic Table.
- Allow for responses and discussion related to the questions.
- Distribute Periodic Table of Elements content pages. Read and review the information with the students. Save the final question for the lesson closing. Use the additional resources to enhance understanding.
- Distribute Activity pages. Read and review the instructions. Assign one or more elements for students to research. Allow access to the Internet and time for the research.
- Once completed, each student will present the information to the class.
- Distribute Practice page. Check and review the students’ responses.
- Distribute the Homework page. The next day, check and review the students’ responses. Students correct the False statements.
- In closing, ask students: The Periodic Table changes very little and most likely will not change in the future. What other things in life do you think could be organized on a chart like the Periodic Table? Give an example.
