Description
When Bonds Break: A Problem-Based "Chemical Bonding" Unit for High School Chemistry (PBL)
Story:
A woman is found dead in her apartment and all signs point to accidental carbon monoxide poisoning. But is the case really that simple? Students solve the case while learning about ionic, covalent, and metallic bonds.
Please see the preview for a list of materials and first day activities.
This product is also part of a BUNDLE found here.
Objectives:
General
- Construct models to express the arrangement of electrons in atoms of representative elements using electron configurations and Lewis dot structures.
- Construct an argument to support how periodic trends such as electronegativity can predict bonding between elements.
- Name and write the chemical formulas for ionic and covalent compounds using International Union of Pure and Applied Chemistry (IUPAC) nomenclature rules.
- Classify and draw electron dot structures for molecules with linear, bent, trigonal planar, trigonal pyramidal, and tetrahedral molecular geometries as explained by Valence Shell Electron Pair Repulsion (VSEPR) theory.
- Analyze the properties of ionic, covalent, and metallic substances in terms of intramolecular and intermolecular forces.
NGSS
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. 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
