Description

Shift student understanding of equilibrium with this bundle of 3 comprehensive Carolina chemistry kits. Bundle includes a demonstration kit and 2 classroom kits. Demonstration materials are sufficient for 5 demos; classroom kit materials support 10 groups of 3.

Shift student understanding of equilibrium, plus save time and money, with this kit bundle. It includes a demonstration kit, Carolina Chemonstrations®: Under Pressure Kit (item #840364), and 2 classroom kits, Carolina ChemKits®: Chemical Equilibrium and Le Châtelier's Principle Kit (item #840709) and Inquiries in Science®: Attaining Equilibrium Kit (item #251213). Combined, the kits have enough materials for 5 demonstrations and lab activity materials for 10 groups of 3.

Begin with the Carolina Chemonstrations®: Under Pressure Kit (item #840364), a small-scale demonstration with a big color change. Students receive a visual cue as they observe the effects of pressure changes on the solubility of carbon dioxide in seltzer water. To demonstrate understanding, students explain and illustrate what is happening on a particulate level.

For a hands-on introduction, Carolina ChemKits®: Chemical Equilibrium and Le Châtelier's Principle Kit (item #840709) offers a safe approach using everyday materials (tea, starch, and milk of magnesia). Students alter reactants or temperature and then discover how their changes shift the reaction equilibrium. In addition to writing balanced chemical equations and equilibrium expressions, students calculate the Ka of acetic acid as their final lab activity.

Finally, Inquiries in Science®: Attaining Equilibrium Kit (item #251213) provides a guided-inquiry exploration of reversible reactions. Hands-on activities in this kit include:

  • Shifting the equilibrium reaction of a weak organic acid
  • Determining the solubility product Ksp of a slightly soluble base
  • Shifting equilibrium through the common ion effect
  • Designing an experiment based on Le Châtelier's principle

These activities help students meet the NGSS Performance Expectation HS-PS-1-6: Refine the design of a chemical system by specifying a change in conditions that would produce increased amounts of products at equilibrium.

The bundle includes FREE 1-year access to digital resources that support 3-dimensional instruction for NGSS.
