Description
Simplify stoichiometry for your students while saving time and money with 3 comprehensive Carolina chemistry kits. The bundle includes 1 demonstration kit, Carolina Chemonstrations®: Balloon Stoichiometry Kit (item #840366), and 2 classroom lab kits, Carolina ChemKits®: Introduction to Stoichiometry (item #840717) and Carolina ChemKits®: Balancing Chemical Equations (item #840656).
Begin (or wrap up) your stoichiometry lesson with a fun, memorable demonstration of limiting and excess reagents with Carolina Chemonstrations®: Balloon Stoichiometry Kit (item #840366). Students watch balloons inflate with carbon dioxide to different sizes from the reaction of sodium bicarbonate and hydrochloric acid. They’ll learn that both the relative size of the balloon and the pH indicator color change in the flask result from the acid and base varying between limiting and excess. Students write a balanced equation for the reaction and identify limiting reagents. The demonstration requires approximately 20 min, and the materials are sufficient for 4 demonstrations.
Students get hands-on stoichiometry practice with Carolina ChemKits®: Introduction to Stoichiometry (item #840717). This multi-activity kit allows students to predict the mass or volume of reaction products, calculate percent yield and percent error, and write balanced chemical equations. The labs require approximately 90 min and can be completed during separate class periods. Kit materials are sufficient for 30 students working in groups of 3.
Shore up your students’ balancing equations skills with the highly popular Carolina ChemKits®: Balancing Chemical Equations (item #840656). This teacher favorite introduces and reinforces the Law of Conservation of Mass using colorful manipulatives and a unique balancing equations mat. The activities help students understand the difference between coefficients and subscripts in chemical equations. Kit activities can be used as time allows for 10 groups, pairs, or students working individually. Materials are reusable.
