A football, a piece of thermocol etc. float on water while a cricket ball, a spoon etc. sink. After doing the experiment, write

1.The iron nail sank in the water but the katori floated. I think this happened because the weight of water displaced by the iron was less than it but the weight of water displaced by the katori was more than it.

2. The empty plastic bottle floated on water. The bottle filled with water sank because the weight of water displaced by the empty plastic bottle was more than its weight but the weight of bottle filled with water was more that that of the weight of watered displaced by it

3. The aluminum foil floated when it was spread out. When pressed tightly into a ball it sank. This may have happened because the weight of aluminum foil is less than that of water displaced by it but the weight of aluminum ball is more than that of the water displaced by it
