What is sound 4th grade science?

Sound is a form of energy. Sound energy is all about vibrating air, water, wood, whatever material the vibration/mechanical motion is near. Sound energy travels most efficiently through solids and least quickly through gases because of how the particles are arranged in each material.

How does sound travel 4th grade?

Sound waves are mechanical waves that transfer energy via the propagation of vibrations through matter. When sound waves move through matter, the matter undergoes compression (the molecules get closer to each other), followed by expansion (molecules move apart). Sound waves can move through gases, liquids, and solids.

How does science explain sound?

Sound is a type of energy made by vibrations. When an object vibrates, it causes movement in surrounding air molecules. These molecules bump into the molecules close to them, causing them to vibrate as well. This makes them bump into more nearby air molecules.

What is a sound wave 4th grade?

Sound is not visible, but it travels as a longitudinal wave that causes air particles to vibrate. The particles vibrate in the form of a wave as the sound travels through the air.
