A
Present counter examples and arrange materials of different shapes, sizes and weights for the child to investigate
B
Explain that heavy and light are relative terms
C
Accept the statement as it indicates child's ideas and needs to be respected
D
Explain to the child that it is not the weight but the density of an object that determines whether it is going to sink or float
