3-Dimensional Assessments and Helping Students Develop the Necessary Skills

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.

Reviewing the Periodic Table Using Mystery Puzzles

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.
