Dr. David Jouandot's Physical Science Honors students used planning skills, logic, and trial-and-error to construct a flowchart that details how to separate a mixture of sand, iron filings, sodium chloride, and stearic acid. They first perform a warm-up activity to determine the mixture components' physical properties. Students then compete in teams to successfully separate the mixture using various separation techniques they learned in class. Being an inquiry lab students compete to see who's technique works the best.
