You are likely aware that diamonds are converted - albeit slowly - to graphite under normal conditions. Thus, diamonds don't last forever, in contrast to the popular advertising slogan. However, did you know that you can use chemistry to prove that diamonds are not forever? It's simpler than you think...
I added an extra step including a follow up Claim, Evidence & Reasoning activity to the familiar whoosh bottle activity.
Recent efforts have recognized the Framework for K-12 Science Education and the Next Generation Science Standards as the most current research regarding what we know about teaching and learning of science, and have suggested that 3-dimensional (3D) instruction should guide science instruction at not only the K-12 level, but also at the college level.
Light is a challenging topic in chemistry. In this article, I share an outline of how I approach the content related to interactions between matter and light using activities, a simulation, demonstrations and whiteboards.
Erica Jacobsen shares highlights from the October 2018 issue of the Journal of Chemical Education.
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.
Looking for funds to attend professional development? I used an ACS Hach Grant to fund my travel to a conference last summer.
Radium Girls is one of those books that can’t be put down. It challenges us with imagery so vivid that sometimes you just want to look away, but you are so invested in the lives of the girls that you persevere to the end. It is tragic and strong but also hopeful and tender.
