Activity - Pressure and Depth

• Students use a spouting jar and liquid levels application to investigate the relationship between pressure and depth.

Activity - Capillarity

• Students use glass capillary tubes to investigate the force of adhesion between water and glass.

Activity - Viscosity

• Students use ball bearings, a magnet and a measuring cylinder to compare the viscosity of different liquids.
