An eighth class student makes the statement:
"Heavy objects sink in water and light objects float." How is the science teacher of the VIII class best advised to react?
1
Accept the statement as it indicates child's ideas and needs to be respected.
2
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.
3
Present counter examples and arrange materials of different shapes, sizes and weights for the child to investigate.
4
Explain that heavy and light are relative terms.
