In this lab activity, students will investigate the characteristics of a chemical change. Students will also provide a definition of what constitutes a physical change through observation of several examples. Students will develop (through discussion) and use the criteria for identifying a chemical change. Several examples of a chemical change will also be observed for students to compare to physical changes. The students will use the five characteristics of chemical change to determine/judge whether or not baking soda, citric acid and water creates a chemical change. Students will write down observations of the reaction and use the five characteristics to explain why it is in fact a chemical reaction (The five characteristics will be listed for use).
