The Observing Chemical Changes Lab allows students to safely explore the mixing of chemicals to search out evidence for a chemical change. Students have over 20 combinations of chemicals which will yield color change, fizzing and bubbling, temperature change and solid precipitates forming form the mixture to two liquids. This packet includes the lab instructions, data chart, answer key, and reflective questions. Also included are complete instructions for the teacher for mixing stock solutions, setting up the lab, and safety concerns for teacher and students. The packet includes files as Word documents and PDF documents.
The Chemical Changes Lab goes well with the Mystery Solutions Lab and the Mad Scientist Lab. All three labs use the same chemical stock solutions (mix them once for all three labs).
