States of Matter

Performance Expectation

MS-PS1-4: Develop a model that predicts and describes changes in particle motion, temperature, and state of a pure substance when thermal energy is added or removed.

In Student-Friendly Words...

I can explain how heating and cooling affect the movement of particles and the state of matter.

Big Ideas

Matter exists as solids, liquids, and gases.
Particles are always moving.
Adding or removing thermal energy changes particle motion.
Changes in particle motion can cause changes of state.

Real-World Connections

Cooking

You see matter change states whenever ice melts, water boils, or steam condenses while you're cooking.

Weather

Clouds, rain, snow, and ice all involve water changing between different states as Earth's atmosphere changes.

Refrigerators & Freezers

Understanding how matter changes state helps engineers design refrigerators and freezers that keep your food cold.

Everyday Life

Knowing how materials respond to heating and cooling helps you understand everything from melting chocolate to why your windshield fogs up.
