文摘

An activity in which students use toy interlocking building blocks to build representations of ionic formulas is described. Students explore cation-to-anion ratios using interlocking toy brick-like blocks to represent trivalent, divalent, and monovalent cations and anions. Students who participated in the building blocks activity showed significantly higher posttest scores than students who had not participated.
