Who is the Atom Economy poster for?

Atom Economy belongs to the Chemistry section rather than to a school year, because physical science is not something one grade owns. Anyone learning calculations can pin it up — a beginner, a student mid-course, or someone revising years later.

When should you use the Atom Economy poster?

Yield measures the reaction's efficiency. Atom economy measures the route's. A wall chart earns its place by being glanceable from where the work is happening, so Atom Economy belongs on the wall where that physical science work actually happens, within glancing distance, rather than filed away.

What other posters go with Atom Economy?

Formula Summary, Concentration and Dilutions sit alongside Atom Economy in the Chemistry section. Printed together they make a wall rather than a single sheet, which is how a reference set actually gets used.Formula SummaryConcentrationDilutions
