Fun with triboelectricity

Highlights from our last training: We discussed triboelectricity and how rubbing materials transfer electric charges from one material to another. We started the experiment with a balloon and a towel. Rubbing the inflates balloon with the towel transfer charges to the balloon making it negatively charged. Then we saw how the balloons repelled each other […]

THE SCIENCE OF SOUND

*THE SCIENCE OF SOUND* Sound is produced when something vibrates. The vibrating body causes the medium (water, air, etc.) around it to vibrate. Vibrations in air are called traveling longitudinal waves, which we can hear. Sound waves consist of areas of high and low pressure called compressions and rarefactions, respectively. Our project today was centered […]
