Activity Description:

Observing sound propagation in solids in Sound - Class 8 Science Experiment

In this experiment, you will observe the propagation of sound in solids. You will strike one end of a table or a metal/wooden strip and ask your friend to listen to the sound produced while keeping their ear touching the table or the other end of the strip.

Then, they will listen to the sound by lifting their head slightly away from the table or the strip. By comparing the two listening experiences, you will explore how sound travels through solids.

Required Items:

  1. Pen (for striking the table)
  2. Table (for the first part of the experiment) OR
  3. Metal or wooden strip (for the second part of the experiment)

Step by Step Procedure:

  1. Place the table or the metal/wooden strip on a flat surface.
  2. Strike one end of the table or the strip with a pen.
  3. Ask your friend to listen to the sound produced while keeping their ear touching the other end of the table or the strip.
  4. Then, ask your friend to listen to the sound again, but this time by lifting their head slightly away from the table or the strip.
  5. Encourage your friend to note any differences they observed in the sound while their ears were touching the table/strip and when they were away from it.

Experiment Observations:

  1. Your friend’s observations about the sound when their ear was touching the table/strip.
  2. Your friend’s observations about the sound when they lifted their head slightly away from the table/strip.

Precautions:

  • Handle the pen and the table/strip carefully to avoid any accidents.
  • Make sure the table or strip is stable and placed securely on a flat surface.
  • Keep the surroundings quiet during the experiment to minimize interference from other sounds.

Lesson Learnt from Experiment:

Through this experiment, you will understand that sound can travel through solids and how the medium (table or strip) affects the way sound is perceived.
