Boat (61 Near Nature Experiments)

You will need:

1. Clay (which does not disintegrate in the water)
2. A large bowl
3. Tray
4. 2 clear glasses
5. Water

Understand the concepts of buoyancy with
this experiment.

INSTRUCTIONS

1. Place the bowl on a tray and fill the bowl till the brim with water.
2. Next, take a large lump of clay and roll it into a ball. Drop it into the water.
3. The clay will sink to the bottom spilling some water onto the tray.
4. Very carefully, keep the bowl aside, and pour the spilt water into a glass.
5. Now remove the ball of clay and pour water once again into the bowl till it is filled to the brim and place it onto the tray.
6. With the help of an adult, change the
   shape of the clay. Mould it to resemble a boat.
7. Try floating it in the water.

RESULT

The remoulded clay will not only float in the water but also displace the water which would have spilt onto the tray. Carefully keeping the bowl aside, pour the spilt water into a fresh glass and compare the amount spilt with the amount of water in the first glass. The boat-shaped piece of clay maybe dense but is also buoyant and helps float the clay. Any object, if it floats on water, will displace the same amount of water as the weight of the object. Hence the amount of water displaced the second time was greater.
