Thirteen chemistry terms cross an 11x11 grid in this medium difficulty puzzle, the first of the standard-level set. Clues reach across a full middle school unit: the substance with pH above seven, the bond that shares electrons, the Bunsen heating device on every lab bench, and the balanced chemical sentence students practice writing. The longest answers stretch to eleven letters, so finishing feels like a real accomplishment rather than a formality.
