Lesson summary

This lesson on the history of the periodic table centers on the story of Dimitri Mendeleyev, the Russian chemist credited with developing the Periodic Table of Elements. He tells about his family and growing up in Siberia, and how he came to organize the elements the way that he did in 1869. Mendeleyev's periodic table looks quite different from the one commonly used today because so much more knowledge about the nature of matter has expanded the modern periodic table. However, Mendeleyev knew there was information scientists were still missing, so he arranged his table with gaps so that new elements could be added when they were discovered. His periodic table proved to be correct. Within a few years of developing the table, the elements he predicted would be discovered were identified by other chemists throughout Europe. The story emphasizes the nature of scientific inquiry and history of science.

Pre-lesson activity

It is recommended that teachers preview the lesson to identify concepts that may need to be reviewed before students begin. Teachers may also wish to create a vocabulary/spelling list for terms found in this lesson.

Teachers may want to pose some questions to students before getting started: How do you think scientists communicated with each other about their discoveries before there was mass communication? How do you think it has changed for scientists working all over the world today? How do you think scientists come up with ideas of the "laws of nature"? Do you think people discover these things alone, or is it the work of lots of people?
