Curriculum Standard(s) Addressed:
This material was used during one class period. Estimated time for completion – half
hour. Students can work separately or in groups.
The materials are presented as a computer based lesson created in Macromedia Flash.
Has some interactivity/animations. A worksheet was used to keep students focused and
provide leading questions to get them thinking about the development of the Periodic
Table. Periodic Tables were provided to each student for completion of the questions.
No official rubric created for this lesson. Since it was an introductory lesson over the
Periodic Table, some previous misconceptions may still be there. The worksheet was
corrected and handed back, but points were assigned based on completion of the exercise.
- This material was used as an introductory lesson on the Periodic Table. It
provided a great set-up for future detailed information and trends in the
- Students can work separately or in groups, but I noticed as they worked in
groups they sounded their ideas out loud to each other, and explained their
reasonings for their worksheet responses.
- It is recommended that the teacher walk around as students complete the
lesson so that questions can be answered.
Handouts for Students:
(Worksheet version 1 goes with PTIntro.swf and contains questions requiring
knowledge of electron configurations s,p,d,f, and ionic charge)
(Worksheet version 2 goes with PTIntro2.swf and does not contain electron
configurations or ionic charge)
