MS-PS4-1
Use mathematical representations to describe a simple model for waves that includes how the amplitude of a wave is related to the energy in a wave.
- Physics
Scientists Say: Ultrasonic
This word describes sound waves that have frequencies too high for human ears to hear.
- Physics
Scientists Say: Radio Waves
Lightning, stars, supermassive black holes and more give off radio waves.

Explainer: Reflection, refraction and the power of lenses
The inner workings of microscopes, telescopes, eyeglasses and other lens-based devices rely on two important laws of optics.
- Tech
Think of this new tech as sunglasses for our windows
Keeping buildings cool can use a lot of energy. Thanks to quantum computing, engineers designed a coating to cut the warming light that enters windows.
- Earth
Scientists Say: Seismology
Seismology is the branch of science focused on seismic waves — vibrations that run through or around Earth.

Cosmic timeline: What’s happened since the Big Bang
Energy, mass and the cosmos' structure evolved a lot over the past 13.82 billion years — much of it within just the first second.
- Archaeology
Muons reveal the inner worlds of pyramids, volcanoes and more
Tracking these subatomic particles can uncover surprising hidden structures.
- Physics
Wild art? No, it’s a radio image of the heart of our Milky Way
Eyelash-like radio filaments accent the brightest feature in this image — a supermassive black hole.
- Physics
Explainer: Telescopes see light — and sometimes ancient history
Different kinds of telescopes on Earth and in space help us to see all wavelengths of light. Some can even peer billions of years back in time.
- Animals
Here’s why ducklings swim in a row behind mom
Baby ducks save energy by surfing their mother’s waves, but only if they do it in an orderly line.
- Brain
A sense of touch could upgrade virtual reality, prosthetics and more
Scientists and engineers are trying to add touch to online shopping, virtual doctor appointments and artificial limbs.
- Physics
Nuclear clocks are nearly here
More precise clocks could improve technologies such as GPS and help scientists test major ideas in science.
