THE MOLE, CONTINUED
Rockets, Reactions and Ratios—
Finding the Empirical Formula of an Unknown
Guided Inquiry Kit
Binary Compound—Student Laboratory Kit
This exciting STEM inquiry-based competition has students find the best rocket-to-baking soda mass ratio to propel a paper rocket 1 meter. Engineering practices join knowledge of chemical reactions and mole ratios in this “rocket fuel” testing lab. Students then identify and test variables that affect the reaction and rocket trajectory. A great capstone project for chemical reactions, stoichiometry and data analy- sis! Complete for 30 students working in pairs.

Limiting Reagent—Student Laboratory Kit
Introduce the concept of limiting reagents in chemical reactions. Students prepare precipitates from varying ratios of barium and iodate ion solutions, measure the insoluble barium iodate that forms and determine excess and limiting reagents. Perform this as a qualitative lab or quantitatively calculate reactants and excess moles. Includes Teacher Notes, reproducible student handouts all necessary chemicals and equipment. Complete for 30 students working in pairs.

Compound InterestTM—The Mole Poster
Bring science to life in your classroom while making connections to the real-world applications of chemistry! The Mole Poster is a great reminder of the importance of Avogadro’s number. Laminated, 24" x 36".
AP9024 | $22.95
Explore the concept of empirical formulas with this engaging activity that studies percent composition and the Law of Conservation of Mass. Each group is given an unknown compound to analyze and determine a formula. Students then decompose the sample by heat- ing it in a crucible, gaining valuable hands-on experience with an analytical balance. Easy to set up and fun! Complete for 28 students working in pairs.
