Is Dancing rice a chemical reaction?
During this chemical reaction,
carbon dioxide is released
. As the carbon dioxide rises toward the surface of the cup, the bubbles attach to the sides of the grains of rice. The bubbles carry the rice to the surface of the water where the bubbles pop and the rice sinks back to the bottom of the cup.
How does the walking water experiment work?

How do sound waves travel?
Sound vibrations travel in a wave pattern, and we call these vibrations sound waves. Sound waves
move by vibrating objects
and these objects vibrate other surrounding objects, carrying the sound along. … Sound can move through the air, water, or solids, as long as there are particles to bounce off of.
What is sound experiment?
Sound is
a disturbance that travels through a medium as a wave
. In this experiment, when you hit the metal pan with the spoon, you disturb the particles of the pan causing them to vibrate. The vibrations in the pan are transferred to the air surrounding the pan, creating a sound wave.

How do sounds travel ks2?
Sound (or vibrations)
enters the ear through the ear canal
. When sound waves reach our ear, it travels through the ear canal and hits the eardrum, causing vibrations. The eardrum sends these vibrations to three tiny bones in the middle of the ear. These are called the malleus, incus, and stapes.
How does a sound wave move through air?
The air is made up of many tiny particles. When sound is created, the
air particles vibrate and collide with each other
, causing the vibrations to pass between air particles. The vibrating particles pass the sound through to a person’s ear and vibrate the ear drum. Light travels much faster than sound through air.

Our eardrums work in a similar way, but instead of from the beat of a drumstick, our eardrums vibrate in response to sound waves hitting it. We can’t see these sound waves with our eyes. But we can see how
they cause vibrations
in things around us, just as they do in our eardrums!
