Activity based teaching learning science floating/sinking

Essence: To develop Concept of Floating and Sinking experimentally, so as to  understand 

1. Iron Nail sink but iron ship floats.

2. Submarine 

Explain: YouTube Video to brief Relative density

Elaborate: Video for ship and submarine:

Explore:

1.Material required: clay, tub/ bowl,  lemon, cork tomato, nail, tumbler, salt

2. Taking a bowl containing water

3. Putting lemon , tomato and nail one by one in water and observe
