Showing Results for sound it out

Every time a sound is produced it emits a sound wave. This experiment demonstrates how sound travels, using nothing more than a spoon and a string!

What causes sound? Here's a simple science experiment that adds a visual element to the science of sound to help kids better understand this tricky concept.

Let your young scientist explore a brave new world of sound with an experiment that just requires a handful of common household items.
