Go Direct® Conductivity Probe

Testing Electrical Conductivity of Metals vs Non-metals

Elements and Compounds

Measure conductivity of metal vs non-metal samples in solution — directly teaches metals are good conductors

Testing Purity by Conductivity

Pure Substance, Mixture and Compound

Compare conductivity of pure water vs tap water (impure) — demonstrates pure substance vs mixture concept

Conductivity Before and After Filtration

Separation of Components of a Mixture

Measure conductivity of water before and after filtration to verify impurity removal

Testing Water Purity by Conductivity

Importance of Water and Its Resources

Measure conductivity of different water sources — pure, tap, river, sea — to demonstrate dissolved impurity levels

Testing Water Pollution by Conductivity

Water as Universal Solvent, Pollution and Prevention

Compare conductivity of clean vs polluted water to detect dissolved pollutants — directly teaches water pollution concepts
