Description
An Aquatic Apocalypse: A Problem-based "Solutions Chemistry" Unit (PBL) for High School Chemistry
Summary:
Millions of fish are dead along a stretch of the White River that passes through Indiana. So, what happened? This problem-based unit asks students to complete a series of experiments to determine the possible cause of the fish kill.
See the Preview for a list of materials and other background information as well as the first day activities.
Each day has an "in-class" and "absent" version of the assignment.
This product is also part of a BUNDLE found here.
Previous knowledge: Students should have already learned stoichiometry.
Objectives:
This problem-based unit was designed to teach the required objectives for solution chemistry in the state of Texas. It would likely work with or without modification in many other venues.
- Interpret, write, and balance chemical equations, including synthesis, decomposition, single replacement, double replacement, and combustion reactions using the law of conservation of mass.
- Differentiate among acid-base reactions, precipitation reactions, and oxidation-reduction reactions.
- Describe the unique role of water in solutions in terms of polarity.
- Distinguish among types of solutions, including electrolytes and nonelectrolytes and unsaturated, saturated, and supersaturated solutions.
- Investigate how solid and gas solubilities are influenced by temperature using solubility curves and how rates of dissolution are influenced by temperature, agitation, and surface area.
- Investigate the general rules regarding solubility and predict the solubility of the products of a double replacement reaction.
- Calculate the concentration of solutions in units of molarity.
- Calculate the dilutions of solutions using molarity.
- Name and write the chemical formulas for acids and bases using IUPAC nomenclature rules.
- Define acids and bases and distinguish between Arrhenius and Bronsted-Lowry definitions.
- Differentiate between strong and weak acids and bases.
- Predict products in acid-base reactions that form water.
- Define pH and calculate the pH of a solution using the hydrogen ion concentration.
