Introduction

1. Take a mug of water filled up to the brim and put any heavy solid object into it (one that sinks). What happens?

2. Try to add more water into the mug. What happens?

3. Invert an "empty" container into the mug of water filled to the brim. What happens now?

  1. Take a tumbler and place it at the centre of a larger container.
    • Take a tumbler and place it at the centre of a larger container.

    • Fill the tumbler to the brim with water.

    • Tie a piece of thread around a stone and dip the stone in the water.

    • What do you observe? If any water overflowed, pour it carefully back into the tumbler. Is it again full right up to the brim?

    • Invert an "empty" transparent tumbler into a container filled with water to the brim.

    • What happens? Does any water overflow? Is the tumbler actually empty?

    Let the pictures reflect what is written in the instructions

    • The stone should easily fit inside the tumbler.

    • The stone should be securely tied to he thread

    • For Steps 1 and 2, the tumbler should be filled completely to the brim with water while the container should be empty

    • For Step 3, the container should be filled to the brim with water and the tumbler empty.

    • What will happen if we blow air into the inverted tumbler? Will the water level rise?

    • What happens when you press a tumbler/tin with a hole at the bottom in a container filled with water?

    • Take a plastic bag, hold its opening and blow air into it. Then, twist its opening preventing the air from going out. What happened to the plastic bag, does gas occupy space in plastic bag? You may also try with a balloon and blow varying amounts of air into it
