Grades 912. Students first use manipulative cards to set up and practice stoichiometric problems. They then obtain data from chemical reactions, which they compare with the results of stoichiometric calculations and determine the percent yield. In the concluding activity, students design and conduct their own experiments to determine the mass percent of sodium bicarbonate in antacid tablets. Materials are sufficient for 32 students working in groups of 4.

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).
