About this worksheet
This comprehension for Year 4 follows a sound from a struck triangle to the brain, over four pages. The text says air particles pass the vibration along 'like a row of falling dominoes' until it reaches the eardrum. It explains that sound needs a medium and that whales hear each other through water. Nine questions follow, from retrieval to an astronaut banging a drum in space and a whistle at the far end of the playing field. The answer key includes a model answer for the last question. Two Year 4 sound objectives from the England National Curriculum are covered.
