Imagine the lively hum of a classroom suddenly bursting into laughter and friendly competition as students engage in a spirited game of rock-paper-scissors. But this isn't just any game; it's the Ion Chip Challenge, a clever and engaging way I help my students grasp the tricky concepts of ions in chemistry.
As sort of a Counting Orbitals I— Appendix, I have invested in a set of painted 100 1" wooden cubes. They can be obtained from your local or online retailer in 8 colors—4 colors with 13 cubes and 4 other colors with 12. Please refer to the Powe
I am a 7th grade teacher who has been teaching a semester of physics and a semester of chemistry at the Harker School in San Jose, CA for the last twenty years. Early on in my career, I made a few observations based on the reactions of my students when I introduced the periodic table of elements to them.
This past July, I had the opportunity to present “Making Chemistry Visible With Magnets” at ChemEd 2019. Additionally, through the creativeness of some fellow attendees, particularly Katy Dornbos, Ariel Serkin, and Kristin
Students typically arrive in my chemistry class with little understanding of light. In spite of focusing on particle representations throughout the year students routinely struggle immensely with drawing particle representations of hydrogen particles emitting four colors of light while 10,000 volts are put across the hydrogen spectral tube.
College Board offers an excellent online resource for teachers and students. It's not free, but my school district pays the bill. AP Insight provides curriculum outlines, teaching ideas and resources, student handouts, and digitally-graded assessments.
I’m sure you have heard that the International Union of Pure and Applied Chemistry (IUPAC) recently announced the verification of four new elements on the periodic table: ununtrium (atomic number, Z = 113, discovered in 2003), ununpentium (Z = 115, discovered in 2004), ununseptium (Z = 117, discovered in 2010) and ununoctium (
