Learners of class-8 Performed Individual activity in which
they observed energy being transferred from one object to another. They have
filled two identical water bottles. Tied a piece of string about 10cm long to the neck of each bottle. Stretched a
piece of string between the two supports and tied securely at each end. The
strings must be high enough for the water bottles to hang down without touching
the surface below. Tied two bottles to the supporting string so they hang down
at equal heights. The learners then described the movement of two bottles and
explained it using law of conservation of energy. The activity enhances
learners understanding of the concepts.
