JCE Classroom Activity
Lego Stoichiometry
J. Eric Witzel
Science Department, Severn School, Severna Park, MD 21146-4599
Cover
March 2002
Vol. 79 No. 3
p. 352A
Abstract
In this Activity, stoichiometry is presented using everyday objects. Lego building blocks are used to explore the relationship between mass and number. Students discover and develop the concepts of limiting reagents and reactants in excess. By providing an introduction to these concepts in a concrete manner, student comprehension can be enhanced.
Supplement

  1. Lego Kit #6437 "Dune Buggy"
  2. Lego Kit #6470 "Mini Dump Truck"
  3. Mega Blocks Kit #9153 "Trekker"
