Grade 6 students conducted an activity to study the density of different solutions – salt solution and pure water as well as to study the density of material. Materials that are less dense than the liquid they are in will float. For example, an egg floats in salt water because the egg is less dense than the salt water. On the other hand, if an egg is placed in fresh water it sinks to the bottom immediately because the fresh water is less dense. Students were able to understand the concept better through experiment.
