  1. Matter What is it?

  2. Matter • Matter is anything that takes up space!!! • Matter is everything around you. • Matter is anything made of atoms and molecules.

  3. Physical Properties • Physical properties can be observed or measured without changing the composition of matter. Physical properties are used to observe and describe matter.

  4. Physical properties include: • Texture • Mass • Color • Odor • Melting point, boiling point • Density • Conductivity • Solubility • and many others.

  5. The mass of an object is a measure of the amount of matter in the object. Mass is a physical property of matter.

  6. What are the three states of matter? • The three states of matter are solids, liquids, and gases!

  7. Solubility • Solubility is the ability of a solvent (like water) to dissolve a solute (like sugar or salt).

  8. Solubility • Some things dissolve easier in one kind of substance than another. Sugar dissolves easily in water; oil does not. Oil has a low solubility in water and sugar has a high solubility in water.

  9. Magnetism • People have known about magnets for thousands of years and they've been using them, as compasses for almost as long. The ancient Greeks and Romans knew as well as we do that lodestone (an iron-rich mineral) can attract other pieces of iron.

  10. DENSITY • Density is the measure of the relative "heaviness" of objects with a constant volume. • For example: A rock is obviously more dense than a crumpled piece of paper of the same size. • A Styrofoam cup is less dense than a ceramic cup.

  11. Floating or Sinking in Water • Density Comparison to Water: In chemistry, the density of many substances is compared to the density of water. Does an object float on water or sink in the water? If an object such as a piece of wood floats on water it is less dense than water. If a rock sinks, it is more dense than water.

  12. Which is more dense?

  13. Conductors and Insulators • In a conductor, electric current or heat can flow freely, in an insulator it cannot. Metals are good conductors, while most non-metallic solids are said to be good insulators.
