Product 12739

By: The Flinn Staff

In the Chemical Bonding Activity-Stations Kit, two activities focus on different properties. Students examine ionic, covalent and metallic bonding and the relationships between properties of a material, its structure and chemical bonding.

Product Details

What kinds of forces hold atoms together in a molecule or compound? How does the nature of the forces holding atoms together influence the properties of a material? Use these two activities to investigate ionic, covalent and metallic bonding and to explore the relationships between the properties of a material, its structure and chemical bonding. Each activity focuses on different properties and is a self-contained unit.

• Properties of Solids—Study the physical properties of common solids and investigate the relationship between the types of bonding in a substance and its properties.
• Dyes, Dyeing and Chemical Bonding—The affinity of a dye for a fabric depends on the chemical structure of the dye and fabric molecules and on the interactions between them. Chemical bonding plays an important role in how and why dyes work.

Each activity is designed to take about 25 minutes to complete, with student groups rotating between the stations. Includes Teacher Notes with sample data, extensive background material, reproducible student handouts and all necessary chemicals and consumable supplies.

Complete for 30 students working in groups of three.

Performance Expectations

MS-PS1-1. Develop models to describe the atomic composition of simple molecules and extended structures.
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.
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.
MS-PS2-3. Ask questions about data to determine the factors that affect the strength of electric and magnetic forces
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-PS1-2. 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.
HS-PS1-3. Plan and conduct an investigation to gather evidence to compare the structure of substances at the bulk scale to infer the strength of electrical forces between particles.
HS-PS1-7. Use mathematical representations to support the claim that atoms, and therefore mass, are conserved during a chemical reaction.
