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.

     

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... 

     

Light is a challenging topic in chemistry. The author, Scott Milam, shares an outline of how he approaches the content related to interactions between matter and light using activities, a simulation, demonstrations and whiteboards.

     

The author shares a five puzzle mystery that aligns with her chemistry curriculum after instruction on the properties of elements and electron configurations. She uses 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.

Allison Tarvin explains a lab she uses in AP chemistry to review and reinforce lab techniques, for example, making solutions, diluting solutions, and decanting liquids. She uses the experience to prepare students for kinetics, equilibrium, and titration labs that will follow.
