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. I have four periodic table ties and a periodic table bow tie. My wife went to Florida for a week to take care of her sick mother and while she was gone, I bought a periodic table shower curtain. I learned two things pretty quickly. Eight year old boys can't keep secrets (my son specifically) and as much as my darling wife loves me, she drew the line on the shower curtain. It was her or the shower curtain. So, I took it to school and tried to put it in the one place that made sense...next to the safety shower.
Celebrating National Chemistry Week 2015: Chemistry Colors Our World
The October 2015 issue of the Journal of Chemical Education is now available online to subscribers. National Chemistry Week, a community-based annual event uniting ACS local sections, businesses, schools, and individuals in communicating the value of chemistry in our everyday life, is being celebrated October 18–24, 2015 with the theme “Chemistry Colors Our World”. Articles in this issue can help you make the most of this annual celebration.
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. Combining creative ideas from an AP Lit project with my honors chemistry content, I am brainstorming about a more engaging, more challenging summative assessment on periodic table families. I would love to hear your ideas and collaborate to build an exciting assessment.
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?
This worksheet is intended to be used as a "Guided Instructional Activity" (GIA). It asks students to find the molar mass of selected elements and write the molar mass as two equivalent fractions ("conversion factors") and as an equality. In each representation, students are forced to give the numeral of the measure, unit, and identity of the chemical.
