MS-PS1-1
Develop models to describe the atomic composition of simple molecules and extended structures.
- Physics
This weird ice may exist on alien planets
Scientists used high pressure and heat to create plastic ice, which has qualities of both ordinary ice and liquid water.
- Chemistry
Scientists Say: Nucleosynthesis
For this nuclei-forging cosmic process, the Big Bang was just a way to get started.
- Math
Scientists Say: Dimension
The simple concept of dimensions has inspired sci-fi creators to wrinkle time and launch into hyperspace.
- Math
His love of math led to a career in quantum computing
James Whitfield began his career when quantum computing was still in its infancy. Today, he’s helping to make it more accessible to educators, researchers and others.
- Chemistry
Behold the world’s thinnest pasta
Made from white flour and formic acid, the nanofibers average just 370 nanometers across. That’s two-hundredths the thickness of a human hair.
- Archaeology
Let’s learn about radiocarbon dating
Through the power of radioactivity, carbon dating can reveal the age of many fossils and artifacts.
- Physics
Experiment: Make your own cents-able battery
Make your own ‘voltaic pile’ with pennies and nickels, and find out how many coins will make the most electricity!
- Tech
Artificial intelligence helped design a new type of battery
Supercomputing and AI cut the early discovery steps from decades to just 80 hours. The process led to a new solid electrolyte.
- Science & Society
Scientists Say: Model
Models are representations of real-life systems or processes that we use to ask questions, make predictions and test our knowledge.
- Climate
Chemists make device to destroy planet-warming methane pollution
It can slash diffuse sources of this extremely potent greenhouse gas, such as from livestock barns and other sites.
- Chemistry
Pollution power? A new device turns carbon dioxide into fuel
Scientists made a device that converts the greenhouse gas into formate. This salt can then run a fuel cell to make electricity.
- Environment
New ultrathin materials can pull climate-warming CO2 from the air
To slow global warming, we’ll need help from CO2-trapping materials. Enter MXenes. They’re strong and reactive — and they love to eat up CO2.
