  • The __________ is the colored part of the eye that controls the size of the pupil.
    iris
  • The __________ is a spiral-shaped part of the ear that converts sound vibrations into nerve signals.
    cochlea
  • he height of a wave, which determines its loudness or strength, is known as its __________.
    amplitude
  • The transparent outer part of the eye is the __________.
    cornea
  • The optic nerve carries sound to the brain. True or false?
    False
  • The bending of a wave as it passes from one medium to another is known as __________.
    refraction
  • Why can’t sound travel in a vacuum?
    Sound cannot travel through a vacuum because there is no air (which means the sound waves can't make vibrations)
  • The __________ is the part of the eye that focuses light onto the retina.
    lens
  • A thin membrane in the ear that vibrates in response to sound.
    Eardrum
  • A back-and-forth motion is called a __________.
    vibration
  • What happens when light bends as it passes through different materials?
    Refraction
  • A __________ is a vibration that travels through a medium, like air, carrying sound.
    soundwave
  • A __________ is a movement of energy through a medium, like air, in the form of vibrations.
    sound wave
  • The amount of sound produced, or how loud or soft it is.
    Volume
  • The __________ transmits visual information from the eye to the brain.
    optic nerve
  • The part of the eye that focuses light onto the retina
    Lens
  • What color are Mr Ethyn's irises?
    Green
  • The distance between two similar points in a wave, like from one crest to the next.
    Wavelength
  • When light does not bounce back or pass through, it is __________.
    absorbed
  • The bouncing back of a wave when it hits a surface is called __________.
    reflection
  • A reflected sound wave that you hear after the original sound.
    Echo
  • The __________ is the clear, outer layer of the eye that helps focus light.
    cornea
  • A __________ is a space that contains no air or matter.
    vacuum
  • The __________ of a sound refers to how loud or soft it is.
    volume
  • A reflected sound wave that you hear after the original sound is called an __________.
    echo
  • The height of a wave, which determines its strength or loudness.
    Amplitude
  • A curved piece of glass or plastic that bends light is called a __________.
    lens
  • The height of a sound wave, or the _________, tells us how loud the sound is.
    amplitude
  • The __________ is the outer part of the ear that collects sound.
    pinna
  • What is the function of the cochlea in the ear?
    The cochlea's function is to convert sound waves into electrical signals that the brain can understand as sound
  • Explain how a rainbow forms in nature using the words "prism" and "refraction."
    The prism refracts white light and splits it into its different parts. The prism refracts white light into a rainbow!
  • The nerve that carries sound signals from the ear to the brain.
