Curated OER
Introduction to Gas Chromatography
Students analyze gas chromatograms and suggest various applications for gas chromatography.
Curated OER
How Can We Accurately Make Different Solutions of Different Concentrations?
Students work together to create different solutions made from different concentrations of liquids. They record and analyze their data. They answer discussion questions to complete the lesson.

Determination of the percentage of Acetic Acid in Vinegar
Students determine the concentration of acetic acid when the concentration of the base with which is titrated is known. They investigate how to weigh a sample using the balance, measure volumes using graduated cylinder, explore the...
Curated OER
A Self Directed Inquiry into the Identification of Unknowns
Students gain experience in designing an experiment and use logic in selecting specific tests for unknowns. Students recognize the use of spreadsheets in helping one to make clear comparisons.
