6 Sound Energy Videos for Kids

These sound energy videos reinforce basic concepts and support this hands-on science unit. First, kids learn that sound is a vibration. Second, they explore how sound travels. In the next two videos, students learn about amplitude and pitch. Finally, they see that sound travels best through solids. More Science Videos

 

Vibrations create sound and move colored sand.
In this video, Science Man explains how sound waves travel.
By tapping on a container filled with water, this video shows how amplitude affects vibrations.
This sound energy video explains pitch.
This video illustrates how adding insulation to a classroom reduces sound.
This sound energy video shows how and why sound travels fastest through solids.

Have some fun! In these sound energy videos, you’ll see sound waves on fire, sound waves in water, and other cool things sound can do.

Review

  • Vibrations cause sound waves, which spread out in all directions.
  • Molecules bump into one another (compress and expand).
  • When more energy is used for a sound, the amplitude (loudness) is increased.
  • As less energy is used for a sound, the amplitude is lower, and the sound is quieter.
  • If sound waves have more room to move, the waves are longer, and the sound produced has lower pitch.
  • Conversely, when sound has less room to move, the waves are shorter and the sound produced has higher pitch.
  • Materials that are harder (denser) allow sound to travel better and are better conductors.
  • On the other hand, materials that are softer (less dense) don’t allow sound to gravel well and are better insulators.
  • Sound can bounce off of smooth surfaces.
  • Because they are dense, solids allow sound to travel faster.

Sound Energy Activities for Kids

Teachers, are you looking hands-on sound activities for your classroom or homeschool? Try science stations! These sound energy videos correspond to a set of six stations that encourage kids to make generalizations.
