Showing Results for ew sound

Find a mathematical relationship between the intensity of a sound wave and distance from the sound source. Use a pedometer and a sound level meter.

How good are humans at sound localization? Kids can try this cool science fair project idea to see how good their friends are at judging sound direction.

Learn about sound physics and do a survey experiment to explore the difference between sound and noise in this science project.

In this cool sound resonance experiment, learn about frequency and pitch, and use a tuning fork to calculate sound velocity in air.

In this activity, you'll send your kindergartener on a scavenger hunt to find sounds and create a sound recording. Here's how!

This science fair project idea produces varying pitches of sound.

Science fair project that examines what causes thunder and why a thunderclap sounds so loud. How is lightening related to the creation of sound waves?

This science experiment tests why guacamole goes brown and if leaving the pit in will stop guacamole from turning brown.

The objective of this experiment is to identify common materials that absorb sound waves with the greatest efficiency.

The objective of this science fair project idea is to determine if sound travels best through the air, water or a solid.

Determine the relationship between the speed of a sound and the temperature of the air it passes through.

Explore how sound waves are reflected and absorbed by producing echoes. Analyze which locations produce echoes.

This classic children's game demonstrates how sound travels through air vs. through a solid.

This classic children's game-connecting two cups with a string-demonstrates sound's ability to travel through air vs through a solid.

This science fair project idea produces sounds by creating vibrations using different objects.

Learn about how we localize objects and beings in space through sound and about monaural auditory mechanisms and binaural auditory mechanisms.

In this sound experiment children listen for differences as they tap on a bag of air, a bag of water, and a wooden block held up to their ears.

This experiment investigates whether there are certain sounds that affect men and women differently

How does a kazoo, the strings of a guitar, or the speaker of a radio make sound? The purpose of this science fair project is to show how vibration makes sound.

This project compares test subjects' responses to whining and other "attachment" and attention-getting sounds to determine which sounds are most distracting.

This science fair project idea shows how a vibrating object transfers energy to whatever it touches.

This experiment will explore how mallets of various materials and weight create sonic tones of varying lengths.

Demonstrate how we are able to locate sounds, echolocation. Have a blindfolded subject locate you by the sound of your clapping.

The goal of this science fair project is to evaluate the effect of heat on sound wave frequency.

Look for a correlation between temperature and the intensity of cricket chirping. Measure ambient temperature and sound intensity in decibels.

This project determines what percentage of test subjects react adversely to the sound of fingernails on a chalkboard and explores their physiological responses.

This science fair project creates a visual model of whatâs happening to sound waves as a car approaches and then leaves.

Tin can phones offer something modern versions don't—a fun project to make with a friend, and a dramatic illustration of vibration and sound waves.

It's the day before the test, and you still have a ton to memorize! Sound familiar? Test memorizing techniques to help yourself out next time.

This activity challenges students to use computational thinking as they create a sequence of commands that will make a robot move in a pattern related to the sound and rhythm of music.
