Last week the students of 2nd ESO studied the properties of matter in the lab: mass, volume and density.

Using a scales, they realised that a balloon filled with air has a greater mass than an empty balloon. They also stablished the volume of certain irregular objects by measuring the liquid displaced inside a graduated cylinder. Finally, after calculating the density of modeling clay they observed its surprising behaviour when submerged in soda water instead of tap water.
