- The child learned about the concept of sound waves and how they travel through the air.
- They learned that yelling or speaking loudly creates louder sound waves compared to speaking softly.
- The child learned that sound waves can be heard by others even if they are far away.
- They learned that sound waves can be absorbed or reflected by different surfaces in their environment.
- The child learned that yelling can cause vibrations in their vocal cords, which produce sound waves.
Continued development related to the activity:
Encourage the child to explore different ways sound is produced and how it travels. They can experiment with musical instruments, make sound with everyday objects, or even try creating their own sound waves using water or other materials. This will help them further understand the science behind sound and expand their knowledge in this area.
