In this lesson, students are offered a variety of alternative versions of the periodic table. Students will identify trends that are consistent from one table to the next in order to understand why the tables they are working with and Mendeleev's version are organized in the manner that they are. This lesson was designed to fit the NGSS performance expectation HS-PS 1.1 but can be used for any first year chemistry course or modified at your discretion.
Chemists tend to think of the Table as an old friend– reliable and static, but that is not the whole story. Piqued your interest? Click on the title to sate your curiosity.
This is a fantastic way to celebrate the birthday of the periodic table of elements! There is still time to get involved and create an element to include when it is put together at a spectacular event October 19, on the campus of Grand Valley State University in Allendale, MI. Extended Deadline!
I have an extreme fascination with the periodic table! And, so does my colleague, Mike. Let me tell you some ways we are celebrating the International Year of the Periodic Table.
National Periodic Table Day is February 7th. Check out some of my favorite periodic table resources.
The American Chemical Society Western Michigan Section is planning a special International Year of the Periodic Table (IYPT) celebration to be held at Grand Valley State University in Michigan on October 19th. The highlight of the celebration will be the unveiling of the largest periodic table in hopes of setting a Guinness World Record. Schools and groups are invited to help with the IYPT project by making one of the 118 elements.
Trends related to placement of elements on the periodic table are often taught using diagrams in a textbook. Students often memorize trends, but to get a true grasp of their meaning and what causes certain patterns is best understood when students create their own models and discuss the patterns with others.
This five puzzle mystery aligns with my chemistry curriculum after instruction on the properties of elements and electron configurations. I use this mystery as a review to prepare for assessments over the properties of elements, symbols on the periodic table and the difference between groups and periods. Also incorporated within the puzzles are basic trends such as the number of subatomic particles, mass number, melting point, and other characteristics of specific elements.
In our recently published letter in the Journal of Chemical Education,"Black Panther, Vibranium and the Periodic Table", we describe how the movie, Black Panther, provides a unique opportunity for students to think critically about the arrangement of the periodic table.
This past March, I ran a multi-day poll on Twitter that was designed to be a fun way to determine the “best” element on the periodic table. I’m sharing about the poll here on ChemEdX in case others might want to try something similar in their classrooms.
