States of Matter Stations

You are a science investigator exploring a kitchen, a cold-weather sidewalk, and a sealed container. Use the questions and the water phase-change table on this worksheet to solve each challenge. Heat energy can move into or out of matter.

Station 1: Particle Clues

Compare how particles are arranged and move in each state.

1.Which state has particles that are close together but arranged irregularly and able to slide past one another?

Solid
Liquid
Gas
All three states

2.A sealed syringe contains air. The plunger is pushed in, making the air take up less space. Which particle property best explains why this is possible?

Gas particles have spaces between them that can be reduced.
Gas particles become liquid whenever they move.
Gas particles are fixed in place.
Gas particles have no mass.

3.Describe how particles move in a solid and in a gas. Include one difference between their motion.

Station 2: Heat and Phase Changes

Follow the changes in a pot of water as energy moves in or out.

ICE solid

→ melting energy enters

LIQUID WATER

→ evaporation energy enters

WATER VAPOR gas

LIQUID WATER

→ freezing energy leaves

ICE solid

4.Mateo leaves an ice cube on a plate in a warm kitchen. What phase change happens, and what happens to the water particles' motion as they gain energy?

5.Water vapor touches the cold outside of a glass and forms droplets. Name this phase change and state whether energy enters or leaves the water during the change.

6.On a very cold day, a thin layer of ice forms directly from water vapor on a window. What is this change from gas directly to solid called?

Melting
Freezing
Deposition
Evaporation

7.At standard atmospheric pressure, water boils at 212°F. A student says boiling water disappears because it turns into a different substance. Is the student correct? Explain using the idea of a physical change.

Station 3: Solve the Mystery

Use evidence from everyday changes of matter to explain what is happening.

8.A balloon is placed over the opening of an empty bottle. The bottle is set in warm water, and the balloon expands. Explain what happened to the air particles inside the bottle.

9.A piece of dry ice becomes smaller in a room while a cloudy-looking mist appears nearby. Dry ice is solid carbon dioxide. Which statement correctly describes the phase change?

It melts from solid carbon dioxide into liquid carbon dioxide.
It sublimates from solid carbon dioxide directly into carbon dioxide gas.
It freezes from gas into solid carbon dioxide.
It evaporates from liquid carbon dioxide into gas.

10.A puddle disappears on a sunny afternoon, even though it never reaches its boiling point. Name the change and explain how it can happen below the boiling point.

11.A freezer changes liquid water into ice. Complete the claim: During freezing, water loses heat energy, and its particles .

12.Choose one phase change from this investigation. Explain what happens to the particles and whether heat energy enters or leaves the substance.
