This picture depicts a scene in the class room.A teacher is guiding four other students on a science experiment.The boy at the bottom right hand corner seemed to be quite interested in what the teacher is doing and is observing the pulley system very closely.The three other students are all jotting down notes and probably also instructions given by the teacher.Group work are part of school and they help to allow students to cooperate and work with one another.Experiments also allow lessons to be learnt in a more interesting way and to allow students to do hands-on on the lessons they have learnt.Thus i believe that experiments are actually as important as lessons from textbooks and schools should have more science practical lessons.
