  2. Objectives : • Matter: Properties/Identify/SmallThe learner will be able to identify that matter has predictable properties and is composed of particles to small too be seen with the naked eye.States of Matter: Conditions/IdentifyThe learner will be able to identify states of matter.

  3. STATES OF MATTER • The Four States of Matter • Four States • Solid • Liquid • Gas • Plasma

  4. Gas • Has no fixed shape • Has no fixed volume • Made of particles that move rapidly • The particles also have large spaces between them in comparison to solids and liquids

  5. Examples of Gases are • Steam • Oxygen • Carbon dioxide • Smog • Tear Gas • Helium

  6. Liquid • Has no fixed shape • Has a fixed volume • Particles move past one another easily • Particles are fairly close, but not in a neat even arrangement as the particles in a solid are

  7. Examples of Liquids are • Orange Juice • Water • Soft drinks • Milk • Rubbing Alcohol • Vinegar

  8. Solid • Has a fixed shape • Has a fixed volume • Particles are arranged • in a tight, regular pattern • Particles move very little

  9. Examples of Solids are • Ice • Frog • Cheese • Bricks • Wood • Popcicle

  10. But what happens if you raise the temperature to super-high levels…between 1000°C and 1,000,000,000°C ? Will everything just be a gas?

  11. STATES OF MATTERPLASMA • A plasma is an ionized gas. • A plasma is a very good conductor of electricity and is affected by magnetic fields. • Plasmas, like gases have an indefinite shape and an indefinite volume. • Plasma is the • common state • of matter

  12. STATES OF MATTER LIQUID PLASMA SOLID GAS Tightly packed, in a regular pattern Vibrate, but do not move from place to place Close together with no regular arrangement. Vibrate, move about, and slide past each other Well separated with no regular arrangement. Vibrate and move freely at high speeds Has no definite volume or shape and is composed of electrical charged particles

  13. Some places where plasmas are found… 1.Flames

  14. 2. Lightning

  15. 3. Aurora (Northern Lights)

  16. The Sun is an example of a star in its plasma state

  17. Writing Activity • The students will describe the three states of matter and include the following : • At least one example of each state • A description of each state
