MS-PS1-1
Develop models to describe the atomic composition of simple molecules and extended structures.
- Physics
Scientists Say: Neutron
Neutrons are one of the main building blocks of atoms and have no electric charge.
- Physics
Explainer: What are the different states of matter?
Most people know solids, liquids and gases — but what about the four other states of matter?
- Chemistry
Lego-like way to snap molecules together wins 2022 chemistry Nobel
This so-called ‘click chemistry’ allows scientists to build complex molecules in the lab and in living cells.
- Chemistry
Scientists Say: Proton
These positively charged particles are important building blocks in atoms.
- Chemistry
Simple process destroys toxic and widespread ‘forever’ pollutants
Ultraviolet light, sulfite and iodide break down these PFAS molecules faster and more thoroughly than other methods.
- Chemistry
Let’s learn about diamond
Diamond is born under extreme heat and pressure inside Earth and elsewhere in the universe.
- Earth
Tiny gemstones show when Earth’s crust first started moving
Chemical hints observed in zircons suggest when the important process of plate tectonics first took off.
- Planets
Mercury’s surface may be studded with diamonds
Billions of years of meteorite impacts may have transformed much of Mercury's graphite crust into precious gemstones.
- Tech
A new device uses atoms’ quantum weirdness to peer underground
Quantum sensors like this one could monitor magma beneath volcanoes or uncover archaeological artifacts.
- Chemistry
New process can transform urban CO2 pollution into a resource
Researchers have developed a liquid metal that breaks down carbon dioxide in the air, converting it from a climate threat into a valuable raw material.
- Earth
Widely used pesticides may threaten Earth’s ozone layer
Data show a major class of long-used “eco-friendly” copper chemicals unexpectedly react with soil, making gases harmful to Earth’s protective ozone layer.
- Chemistry
No, organic molecules alone don’t point to life on Mars
These carbon-based molecules, found in a meteorite, may reflect merely a mixing of water and minerals on the Red Planet over billions of years.
