Many novice students struggle to see elements' valence electron configuration trends across the rows and columns on the periodic table. There are many diagrams and explanations available as resources for students however, a deeper understanding may be possible when students discover these trends independently through a game called Electron Configuration Battleship.
Rajasree Swaminathan has developed a series of books that combines story-telling and visual representation of the elements as human characters. Along with hands-on activities, these books have created enthusiasm in her chemistry classes.
Teaching about hypervalent structures is problematic. This post discusses a simple and quick way in determining the number of lone pairs on a hypervalent central p-block atom.
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!
In honor of the International Year of the Periodic Table, Tom Kuntzleman decided to write a song, sing it, and shoot an accompanying video to honor 150 years of the Periodic Table of Elements. Enjoy his song and video: Chemistry is Everywhere!
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.
I recently attended a workshop at my state conference about improvisation techniques to use in the classroom. As a teacher we are challenged to constantly adapt our pedagogical techniques to meet the needs of our learners, and this workshop provided some new strategies to do just that.
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.
The University of Waterloo is doing another collaborative project! If you missed out on participating in our 2011 Periodic Table Project, this is your opportunity to have your students celebrate and be part of a worldwide initiative.
