Inquiries in Science® Chemistry Series - Help your students understand hard-to-grasp science concepts. Using a learning cycle of Engage, Explore, Explain, Extend, and Evaluate, each kit features lab activities designed to actively engage students in learning essential science concepts through guided inquiry. 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.

The Changing States of Matter Kit includes: Lab supplies plus a teacher’s manual with instructions Background information Reproducible student sheets Student questions Extension activities Grading rubric Suggestions for differentiated instruction

• Develop a heating curve to show different phases of water
• Investigate the effects of pressure and temperature on water
• Design and conduct a separation experiment

Grades 9–12. This hands-on kit uses a guided-inquiry technique as students work together to experimentally produce partial heat curves and phase diagrams for water. Through these activities students develop an understanding of the states of matter and investigate the effect of pressure and temperature on water. As a final activity, students are challenged to develop and perform a protocol for purifying glycerol from a mixture of glycerol and water, plus they develop a protocol for demonstrating the relative purity of the glycerol.

Part of the Inquiries in Science™ series. Materials are sufficient for 30 students working in groups of 3.
