today on Nov 13, room 7 made a Science DLO Of making what is sound and How a human ear works. we watched a video named SciKids it made us understand more about what is sound and we learned about how other animals have other types of ears. Here is the DLO I made!

If you cant see the text here!
(the red one) What’s the meaning of sound? Sound is when the vibrations of the air makes a wave and travel through the air, water or solid stuff. Sound is produced when an object vibrates, creating a pressure wave. This pressure wave causes particles in the surrounding medium (air, water, or solid) to have vibrational motion. As the particles vibrate, they move nearby particles, transmitting the sound further through the medium. The human ear detects sound waves when vibrating air particles vibrate small parts within the ear
(the yellow one) How the human ear works.
The Outer Ear
The auricle is the visible portion of the outer ear. It collects sound waves and channels them into the ear canal where the sound is amplified.
The Inner Ear
The sound waves then travel toward a flexible, oval membrane at the end of the ear canal called the eardrum, or tympanic membrane. Sound waves cause the eardrum to vibrate
