  2. Matter is anything that occupies space and has mass. Teacher, what is matter? • 2

  3. Three states of matter Solid-rigid materials with definite shape and volume. Liquid-definite volume independent in each container but has no definite shape. Gas-has no definite volume and shape.

  4. Molecular Structure of Solid • Particles in a solid are tightly packed, usually in a regular pattern. They vibrate (jiggle) but generally do not move from place to place.

  5. Molecular Structure of Liquid • Particles in a liquid are close together with no regular arrangement. They vibrate, move about, and slide past each other.

  6. Molecular Structure of Gas • Particles in a gas are well separated with no regular arrangement. They vibrate and move freely at high speeds.

  7. Physical Properties of Solid Color- orange Shape- round Size- big Texture- rough

  8. Special Properties of Solids • Malleability- the ability of solids to be hammered into thin sheets. • Hardness- the ability to resist physical changes. • Strength- A measure of a material's resistance to failure. • Brittleness-the ability of matter to be broken down into pieces.

  9. Properties of Liquids • Have no definite shape. • Have definite size and amount. • Take the shape of their containers. • Move freely or they have the ability to flow.

  10. Properties of Gases • They are easy to compress, • They expand to fill their containers, and • They occupy far more space than the liquids or solids from which they form.

  11. Measuring Matter • Matter can be measured. Measuring devices that are used are the weighing scale, ruler, meter stick and graduated cylinder and tape measure.

  12. Good Effects of Matter Matter is everywhere. We can see it in the kitchen, garden , dining area and many more. Solid objects like books, ball pen and paper are used in the school. Substances such as soy sauce and fish sauce are use to give taste to the foods we eat.

  13. Bad Effects of Matter If matter is not properly utilized like the knife , it will cut your hand or finger. Thus, if matter is not place in it’s right place for example the pesticides, children may reach it and it will poison them.

  14. Safety Measures • Label the containers. • Read directions before using. • Return things to their proper places. • Keep harmful substances and breakable objects away from children. • Ask the assistance of older people.

  16. Weighing Scale To cause the bend down with added weight.

  17. Inch ruler Straightedge strip as of wood or metal for drawing straight lines and measuring lengths.

  18. Graduated Cylinder A solid bounded by two parallel planes and such a surface, especially such a surface having a circle as its directrix.

  19. Meter stick To measure with a meter. To supply in a measured or regulated amount

  20. Tape Measure A tape of cloth, paper, or steel marked off in a linear scale, as of inches or centimeters for taking measurement.
