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.
With the start of the school year quickly approaching or having already started for others I wanted to take this chance to update a few resources regarding some periodic table websites and apps for you and your students.
In the August 4th issue of Science Magazine, author Mary Soon Lee shared a review of a periodic table that contains haiku for each element. There is an interactive periodic table you can click on; it was easily viewable in the mobile version of the article.
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.
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.
Our new administrative team now strongly encourages all core content teachers to provide a summer assignment to prepare students for the first day of school. Outside of the summer reading for literature classes, we’ve never done this. I see the potential for class time-savings and improvement of student understanding. Will the students see the possibilities? What should I assign? Is it realistic to expect next year to begin differently?
Have you ever wondered what is the theoretically largest possible value for the atomic number of an element? Using some introductory physics and algebra, you can get your students thinking about this idea.
I love the periodic table. I love the order, the stories, the trends and patterns, the people who made it. I love how it can be used. I love that it is the ultimate cheat sheet for a scientists or a student taking chemistry. I love the different types of periodic tables that exist. My love for this table is pretty evident.
Science is creative; it requires new ideas, new patterns, and new solutions to old problems. A deep understanding of the periodic table is the most critical knowledge in chemistry. I want my students to experience the table and conceptualize its trends in a deeper way.
TV and movie screens today offer us a desperate fight against crazy-fast zombies, a peek into celebrities’ lives where truth is often stranger than fiction, million-dollar game shows, and more. Can portraits of science compete?
