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.
This virtual adaptation provides students the opportunity to engage in a process similar to the one Mendeleev used as he constructed the original version of the periodic table we still use today.
National Periodic Table Day is February 7th. Check out some of my favorite periodic table resources.
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.

My plans for the introduction of the periodic table for my chemistry course. Resources include a document that I use to help students with vocabulary and key points as well as my recommendation for a Target Inquiry activity to use with your students.
Previously I wrote about taking part in a district-wide high school blended learning pilot. You can read about it here. I received my Chromebook cart near the end of February/beginning of March. A little late but just in time for the periodicity unit I was planning as a blended unit. The following is a breakdown of how I designed the unit.
Upon sharing my array of apps with some future chemistry teachers, they asked why so many Periodic Tables? My response was “Well not all periodic tables are the same”, upon which was followed by several blank stares...Let me explain: I currently have the following periodic table apps loaded on my iPad...
Are kids learning? Given the time it takes to implement and grade the activity, do I get a lot of "educational moments" out of it? Does it fit into the culture of the classroom? Is there a great deal of "conceptually rich" material in the activity that students can build on? I believe that two activities I tried this week fit the bill.
