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.
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.
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.

Do you require your students to learn all the element names and symbols? Do your students struggle with chemical nomenclature, chemical equations, or stoichiometry? You may want to consider getting them back to the basics.
Every LED light has a "band gap". Electrons are pushed into an empty orbital which is negative and then the positive end of the circuit attracts the electrons. As they go down in energy through the band gap, they emit light. The larger the band gap, the more energy, the smaller the wavelength and the closer to the "blue" end of the spectrum. So, the key is to try to control the band gap and thus control the color of light.
It was a familiar childhood sound. You know that sound? A bin of Lego building blocks. You want that one particular piece. You rake through the pieces with both hands, searching. That noise. It was often heard during my younger years and now filters down from my children’s bedrooms upstairs. But, as someone connected with teaching and learning chemistry, I don’t have to leave that toy (or sound) behind.
