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.
- Physics
Scientists Say: Explosion
Explosions happen when chemical or nuclear reactions blow out a lot of heat, noise and expanding gas.
- Chemistry
Experiment: Keep your candy cool with the power of evaporation!
In this science project, use the energy produced when water evaporates to cool down chocolate-covered candy so it doesn't melt.
- Chemistry
Scientists Say: PFAS
Non-stick coatings, stain-resistant cloth and other common materials leach long-lived PFAS into soil and water.
- 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.

How daylight saving time throws off your internal clock
Turning the clock ahead knocks our bodies and brains out of sync with the sun. That leads to many potential health issues.

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.
- Physics
Scientists Say: Fusion
Nuclear fusion is the physics that powers the sun and could someday provide abundant clean energy on Earth.
- Chemistry
Forensic scientists are gaining an edge on crime
Advances in forensic science are helping to recover invisible fingerprints and identify missing people from bits of tissue or bone.
- Chemistry
Scientists Say: Fluorescence
This property causes materials — including some animals’ skin, fur or feathers — to glow under light.
- 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?
