Option 2 : Engaging the students in floating and sinking activities with carefully selected materials.
Archimedes' principle states that the upward buoyant force that is exerted on a body immersed in a fluid, whether fully or partially, is equal to the weight of the fluid that the body displaces.
Here Engaging the students in floating and sinking activities with carefully selected materials will be the best because here students
- get an opportunity to compare various objects' densities by involving in the sinking and floating activities.
- get the same feeling that Archimedes got while he formulated the principle.
- comprehend the concept clearly and remember for a long time because learning by doing happens here.
- clear all the doubts they get because they are not passive, they are involved in the activity.
- develop into young explorers and think innovatively.
Hence option 2 is the correct one.
