The effects of ultrasonic on bacteria count
Introduction:
Ultra sonic waves have many industrial and medical applications. They are known to be safe for human and we can not hear them. Some animals such as mouse , cat and dog who can hear higher frequencies than human can hear ultrasound. 

Ultra sound is used as a repellent for rodents, is used to measure distances, view inside human body, melt fat in liposuction, skin treatment and many more.

Ultrasound may also have some effect on bacteria growth.
 
 Project description:
The purpose of this project is to see if ultrasound affects bacteria growth. In this project you will grow bacteria in two identical environments which one of them is equipped with an ultrasound generator. You will then use any know method of bacteria count to determine if ultrasound had any effect in bacteria count.
