Physics
Scientists Say: Discharge
In physics, this release of energy can rebalance electrical charges. In biology, such a release might cool you down on a hot day.
HS-PS3-2
Develop and use models to illustrate that energy at the macroscopic scale can be accounted for as either motions of particles or energy stored in fields.

Here’s how rainwater might one day power some of your lights
In tests, the electricity that water droplets made was small, but kept a dozen LEDs lit. This tech might one day power clean energy for wet or rainy places.

Physics explains why poured water burbles the way it does
The loudness of falling water depends on the height of the pour and the thickness of the stream.

New device can harvest clean energy from humid air anywhere
Unlike solar power, this new source of electricity is available day or night.

Shouting into the wind may seem futile — but it’s really not
Sending a sound upwind, against the flow of air, actually makes the sound louder — only it doesn’t sound that way to the person making the noise.

Let’s learn about piezoelectric materials
Piezoelectric materials turn mechanical energy into electrical energy — and vice versa.

Scientists Say: Voltage
Voltage is a measure of how much electricity is available to power devices.
- Physics
Scientists Say: Radiation
Radiation is the motion of energy through space as waves or particles.
