What are the important properties of materials?
Let's find out through some activities.
Observe the figure. What are the things required to do
the experiment shown in the figure?
How do we do this experiment?
Try to write down the procedure after observing
Figure 4.1
What happens to the water level when the stone
is dipped in water? What is the reason?
Fill three-fourth of a trough with water. Keep a dry
glass tumbler perpendicularly immersed in water in
the trough (Figure 4.2).
What happens to the water level in the trough?
Does water enter the tumbler?
What material does the tumbler already contain?
Is there a relationship between the volume of this
material and the difference in the water level?.
I will sure mark as brainliest
