Chemical Fate and Transport in Soil and Water is a Grade 12 Science resource examining how contaminants move, change form, and become distributed through soil and water systems. Students investigate dissolution, sorption, volatilization, and biodegradation while connecting contaminant behavior to kinetic and equilibrium processes.

Trace Contaminant Movement

Students explore the processes that control contaminant fate and transport, including how substances move between environmental compartments and change over time. The resource develops scientific reasoning around contaminant distribution, persistence, and partitioning, helping students connect chemical processes with predicted environmental outcomes.

Apply Evidence to Environmental Pathways

Case-study pathways give students opportunities to interpret information and predict likely zones of contamination. They consider how kinetic versus equilibrium processes influence contaminant distribution over time and use these ideas to reason about where contaminants may persist or move within soil and water systems.

Connect Science to Monitoring and Remediation

Students also evaluate monitoring and remediation strategies by considering contaminant persistence and partitioning. This provides a practical context for applying chemical fate and transport concepts to environmental decision-making.

Practice and Assessment Formats

The worksheet uses multiple-choice questions, true-or-false questions, short-answer responses, a reading passage, matching, a cloze passage, an essay, and a did-you-know section. Students encounter opportunities to recall concepts, interpret environmental pathways, predict contamination zones, and communicate scientific reasoning.
