Product 12745

By: The Flinn Staff

In the What is a Chemical Reaction? Chemistry Laboratory Kit, students study the properties of chemicals with a variety of substances to identify signs of chemical change. Students then find patterns in the chemical properties of matter.

Product Details

Chemical change is a central part of our modern world. Although it is responsible for most of the energy, materials and medicines that we depend on in our daily lives, chemical change may be mostly invisible to students. What is a chemical change? How can students identify a chemical change? In this microscale experiment, students study the properties of hydrochloric acid and copper(II) chloride with a variety of substances to observe and identify signs of chemical change. As students gather evidence in this introductory-level experiment, they begin to discover similarities, differences and patterns in the chemical properties of matter. Includes reproducible student handouts, detailed background information, complete Teacher Notes with sample data and answers to questions and all necessary chemicals and consumable supplies.

Complete for 30 students working in pairs. Fifteen reusable, 24-well reaction plates are recommended and available separately.

Performance Expectations

MS-PS1-2. Analyze and interpret data on the properties of substances before and after the substances interact to determine if a chemical reaction has occurred.
HS-PS1-1. Use the periodic table as a model to predict the relative properties of elements based on the patterns of electrons in the outermost energy level of atoms.
HS-PS1-7. Use mathematical representations to support the claim that atoms, and therefore mass, are conserved during a chemical reaction.
