Here's a first grade ladybug game that explores how air can move solid objects, and adds some measurement practice, too. Play, learn, and enjoy!

Get a cool and easy science fair project idea which helps high school students in understanding concepts behind the working of a microphone.

Using an empty tennis ball can and a swimming pool, you will determine if it's possible to have a conversation under water.

This activity is a great introduction to polymer chemistry. It might seem complicated, but all you'll need is the material found inside of a baby's diaper!

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

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.

Most people assume that cold water freezes more quickly, but could that be false? Does hot water freeze faster than cold water? Let's find out!

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

Before digital cameras, before Polaroids, there was the original pinhole camera. Build a pinhole camera and see what true vintage photography looks like!

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