States of Matter Ms. Steele
States of Matter Brain Pop! • http://www.brainpop.com/science/matterandchemistry/statesofmatter/ What are the four states of matter? • How are they all different? • What is plasma and where do we find it? • Which state of matter is the freest?
Solids, Liquids, and Gases Card Game! • You will play with the 2 other classmates at table • 1. There are 3 picture cards (liquid, gas, solid) • 2. Each player will randomly select ONE picture • 3. Shuffle the other cards and spread them face up on the table • 4. Take turns picking a card. • 5. If the card describes your picture, keep it • 6. If the card does NOT describe your picture, place it back on the table face up • 7. The game ends when each player has their set of cards
Card Game Discussion • The particles have almost no movement energy • Solid • The particles are in a fixed position • Solid • The particles have a weak pattern • Liquid (particles can flow freely around each other but are still packed closely together) • It is usually invisible & we can’t feel it • Gas • The particles are spread far apart • Gas
1. Solid • When things are colder, they are usually a solid • It can hold its own shape • High density-molecules are tightly packed • Energy level: low • Example: ice • What are other examples? • What happens if we put a solid in a container?
2. Liquid • Heated solid becomes a liquid • Heated liquid becomes a gas • Example: water • Molecules are less densely packed • They can move around a little more and slide past each other! • Energy level: higher than solid • What happens if we place a liquid in a container?
3. Gas • When things are hotter, they heat up to a gas • Example: vapor or steam • What are other examples? • The atoms are VERY spread out and collide with each other • More energy! (Highest energy of them all!) • What happens if we fill a container with a gas?
4. Plasma • Similar to gas • It has an electrical charge • The atoms are very excited! • Plasma gives off light • It can conduct electricity • Examples: fluorescent lights, neon signs, and lightning • Sun is in a plasma state
Write observations for each photo 1. Write one observation about the solid 2. Write one observation about the liquid 3. Write one observation about the gas
Write observations for each photo 1. Write an observation about the gas 2. Write an observation about the liquid 3. Write an observation about the solid
Which has the most amount of energy? • A. Gas • B. Liquid • C. Solid
