Introduction

Using just a syringe, and air, water and sand as representations of the 3 states of matter, we compare the compressibility of each state.

Video Overview

    • Don't poke yourself with syringe .

  1. Remove the plunger from the syringe
    • Remove the plunger from the syringe

    • Take a small piece of foam , a paper pin and synthetic glue.

    • Seal the tip of the syringe by inserting a small piece of foam through the hole using the paper pin .

    • After inserting the foam piece apply glue at the tip of the syringe . Wait for about 10 minutes for the glue to dry.

    • The tip is sealed.

    • First, we'll conduct the experiment with only air in the syringe. So simply insert the plunger.

    • Then, we'll fill the syringe with water and insert the plunger.

    • Finally, we shall do the same with the syringe filled with sand.

    Vishal:

    The glasses look really dirty. Please replace by a clean one.

    • Press the plunger as far as you can when the syringe is filled with air. Note the position to which you have been able to compress.

    • Repeat the same process with the syringe filled with water.

    • And finally with sand.

    • Can you feel, show and tell which of the three is most compressible and which the least?

    • Make sure that the foam is glued firmly to the tip of the syringe such that it is airtight.

    • Fill the syringe with cotton and try to compress. Record the reading of the syringe here.

    • Remove the foam seal at the tip of the syringe in each of the 3 cases and compress. Record the syringe reading here.

    Vishal:

    (1) Second observation is not actionable. We are not providing mercury and that's not easily available at home/school.

    (2) First one can be reworded as "Fill the syringe with cotton and try to compress. Record the reading of the syringe here."

    (3) Remove the toothpick seal in each of the 3 cases and compress. Record the syringe reading here.
