Balancing Equations: Super Value Kit

By: The Flinn Staff

With the Balancing Chemical Equations Super Value Activity Kit, students use chips as models for atoms and molecules, counting and manipulating the “atom” chips until all atoms are conserved. Students then determine the final equation.

Product Details

Are you looking for a simple and innovative way to help your students visualize the balancing of equations and the Law of Conservation of Matter? Use this hands-on kit to make the abstract concept of “atoms” become more visual and real for students. The activities in this kit utilize colored chips as models for atoms and molecules. Students count and manipulate the “atom” chips until all atoms in the equation are conserved and then write the final equation on the provided data sheets. Detailed activity sheets guide students through the atom-accounting process. Includes a magnetic wand, 100 wire-rimmed counting chips for teacher overhead demonstrations, 1,000 colored chips for student use, background information, reproducible student instructions and data tables. Balance out your curriculum with this Balancing Equations kit!

Super Value Kit is complete for 30 students working individually. All materials are reusable.

Performance Expectations

MS-PS1-1. Develop models to describe the atomic composition of simple molecules and extended structures.
MS-PS1-5. Develop and use a model to describe how the total number of atoms does not change in a chemical reaction and thus mass is conserved.
HS-PS1-7. Use mathematical representations to support the claim that atoms, and therefore mass, are conserved during a chemical reaction.
HS-PS1-2. Construct and revise an explanation for the outcome of a simple chemical reaction based on the outermost electron states of atoms, trends in the periodic table, and knowledge of the patterns of chemical properties.
