This kit is designed for 28 students working in groups of 4. This experiment can be repeated twice. This kit introduces students to chemical equations involving signaler replacement and double replacement reactions. Students have the opportunity to perform two different single replacement reactions and two different double reactions. Observed are color change, formation of precipitates, and production of gases. The kit includes term sheets, activity sheets, laboratory exercises, a crossword puzzle, and a test. The activity sheets give the students practice in writing chemical symbols and formulas for elements and radicals (polyatomic ions) and writing formulas for compounds.

The laboratory exercises give students practice in completing and balancing single replacement and double replacement equations.
