Using an Abbreviation Puzzle as a Method to Familiarize Students with Infectious Diseases

This puzzle is developed by students and a faculty member of Valdosta State University during the Coronavirus pandemic that has brought the world to a standstill. It blends a novel approach to puzzles with an educational activity to serve as a learning tool for infectious diseases. While there is a strong strategic aspect to solving or completing the puzzle, it should also familiarize the participant with the names of infectious diseases and a few facts about each malady.

2. What cues are used to differentiate matter types?

“What cues are used to differentiate matter types?” is a question of differentiation, or telling matter types apart. Differentiation in chemical thinking is based on the assumption that every chemical substance has at least one differentiating property that makes it unique. Good differentiating properties do not depend on the amount of substance under analysis and have unique values for different materials. Examples include boiling points, solubilities in water, and molecular structure. The characterization of these differentiating properties is critical for the design of methods to separate substances, identify them, detect them in our surroundings, or quantify their amounts.
