Question

3. Describe a simple activity to prove that objects of density less than that of the liquid float on it

Answer 1

1.take two liquids of equal volume but different density
2.it should be non reactive
3. pour them into a container
4.observe carefully
"observation"
you would see the lighter would float above the denser liquid

Answer 2

take an iron nail and a cork of same weight. Take a beaker full of water. Put iron nail and cork in the water. You will observe that iron nail sinks whereas cork floats. This is because density of iron nail is more than the density of water so it sinks while the density of cork is less than that of water so it floats. So this activity shows that object with less density than of water floats on water surface.
