Product Details

What exactly is a chemical reaction? How can we identify a chemical reaction? What kinds of evidence can be gathered to determine if a chemical reaction has occurred? In this demonstration, students observe the chemical properties of hydrochloric acid and copper(II) chloride and use the data to describe the types of reactions they undergo. The demonstration integrates observation and measurement skills with new concepts of chemical properties and chemical reactions. Students develop critical thinking skills as they analyze the results and identify patterns in chemical behavior. Teacher Demonstration Notes, along with student worksheets, are included.

Enough chemicals for seven demonstrations are provided.
