Chapter Name: Materials and Things
Activity Name: Do iron objects float? in water in Materials and Things
In this experiment, you will observe the floating behavior of different objects in water. You will test an iron nail, an empty iron tin, a wooden piece, and a wooden bowl to see whether they sink or float in water.
Through this activity, you will understand that the shape of an object can affect its buoyancy in water.
- Wide-mouthed bowl
- Iron nail
- Empty iron tin
- Wooden piece
- Wooden bowl
Step by Step Procedure:
- Take the wide-mouthed bowl and fill it with water.
- Place the iron nail in the water and observe what happens. Record your observations.
- Remove the iron nail from the water.
- Place the empty iron tin in the water and observe its behavior. Record your observations.
- Remove the empty iron tin from the water.
- Take the wooden piece and place it on the surface of the water. Observe whether it floats or sinks. Record your observations.
- Remove the wooden piece from the water.
- Dip the wooden bowl into the water and observe what happens. Record your observations.
- Iron nail: Observe whether it sinks or floats.
- Empty iron tin: Observe whether it sinks or floats.
- Wooden piece: Observe whether it sinks or floats.
- Wooden bowl: Observe what happens when it is dipped in water.
- Handle the iron objects with care to avoid injury.
- Ensure that the bowl is wide enough to accommodate the objects.
- Keep the experiment area clean and free from any hazards.
- Perform the experiment under adult supervision.
Lesson Learnt from Experiment:
From this activity, we learn that the shape of an object can influence whether it sinks or floats in water. Some materials, like the iron nail and the empty iron tin, may sink in their original shape but float when they are in a different shape.
On the other hand, materials like wood may float regardless of their shape. This experiment demonstrates the concept of buoyancy and how it can be affected by the shape and density of an object.
