Grades 912. Students investigate reversible reactions and equilibrium. Using this knowledge, they investigate Le Châtelier’s principle, shifting equilibrium through the common ion effect and by varying the concentration of reactants. Kit includes materials for at least 30 students working in groups.
Grades 912. With this guided-inquiry kit, students investigate reversible reactions and equilibrium. They first shift the equilibrium reaction of a weak organic acid, and then determine the solubility product of a slightly soluble base. Students also investigate Le Châtelier’s principle, shifting equilibrium through the common ion effect and by varying the concentration of reactants. In the capstone activity of this kit, students design an experiment using Le Châtelier’s principle to determine whether an equilibrium reaction is exothermic or endothermic. Kit includes enough materials for at least 30 students working in groups. Receive a FREE digital teacher’s manual and student guide with kit purchase.

Inquiries in Science® is our exclusive series of hands-on kits specifically designed to help high school students understand abstract, hard-to-grasp science concepts. The series tracks well with most textbooks, and kit topics reflect state science standards and extensive educator input. Since Inquiries in Science® is modular, you can use the kits individually, as a strand, or as a series to teach biology, chemistry, and environmental science.
Field-tested in classrooms nationwide, Inquiries in Science® employs guided inquiry based on the 5E learning cycle of engage, explore, explain, extend, and evaluate. This inquiry-based approach also promotes STEM (science, technology, engineering, and math) practices. It enables students to:
Inquiries in Science® helps students build critical-thinking and problem-solving skills, and encourages creativity, collaboration, and teamwork. It creates an environment in which you and your students work together as active learners.
Disciplines and topics addressed by the kits were organized and selected based on data from numerous sources, including the National Research Council's National Science Education Standards, AAAS's Project 2061 Science Benchmarks, NAEP's Science Framework, and state science education standards from across the US. In addition, the Inquiries in Science® content and activities reflect the science practices and engineering practices, core ideas, and crosscutting concepts outlined by the National Research Council's A Framework for K–12 Science Education (2011) and the Next Generation Science Standards (2013).
