How I Learnt How Boats Sink, Float And Topple.

Materials Required
* Plastic boats, * Some tamarind seeds, * Water Tank to float plastic boat
Method
  • Put the plastic boat in the tank of water and observe what you see.
  • Next put some tamarind seeds inside the plastic boat and observe the difference in the position of the boat. 
  • Next repeat the above experiment by putting seeds only on one side and equally on both sides. 
  • Observe what happens in both the cases.  
What is Learnt
The weight on both sides of the boat should be balanced not to topple while going for a boat ride in a river or lake.
Conclusion
The plastic boat floats freely on water first and sinks further as you add more and more tamarind seeds. Further, when tamarind seeds are added on one side of the boat that side sinks more and more and may topple ultimately. However, on balancing the weight of tamarind seeds on both sides the boat sails smoothly.
