Looking at Liquids, Second Edition

Students investigate the properties of liquids beyond how they look, smell, and feel. Your class will operationally define concepts such as cohesion, adhesion, absorption, density, water pressure, and evaporation. Students will examine the sizes and shapes of different drops, design an apparatus to compare the “skin” on liquids’ surfaces, and predict how soap will affect surface tension. Using balances and batons, they explore liquid density and its effect on buoyancy. To conclude, students use litmus paper to categorize liquids as acidic, basic, or neutral on a pH scale.
