MS-PS1-2
Analyze and interpret data on the properties of substances before and after the substances interact to determine if a chemical reaction has occurred.
- Materials Science
Scientists Say: Semiconductor
Modern electronics, from cell phones to video games, work thanks to these conductor-insulator hybrids.
- 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.

Experiment: Test the effect of temperature on reaction time
Alka-Seltzer tablets fizzle furiously when dropped into water. Can you make Alka-Seltzer fizz faster or more loudly by changing the water’s temperature?
- Physics
Scientists Say: Explosion
Explosions happen when chemical or nuclear reactions blow out a lot of heat, noise and expanding gas.
- Environment
Sea life may suffer as plastic bits alter metals in water
This interplay between plastics and metals could affect how each affects the environment — and suggests opportunities for controlling their risks.
- Animals
Let’s learn about frogs
Frogs are a fascinating bunch of amphibians. Unfortunately, they’re also dying off in huge numbers.

Does the size of a parachute matter?
How does a parachute work? Do bigger parachutes work better than smaller parachutes? Find out in this science project whether the size of the parachute matters.
- Chemistry
Scientists Say: Fluorescence
This property causes materials — including some animals’ skin, fur or feathers — to glow under light.
