Measuring with your senses

  1. 1. Physical Properties of Matter
  2. 2. Physical Properties of Matter • A physical property is a feature that you can observe with your senses or measure with a tool. • You can observe physical properties without changing it into a different kind of matter.
  3. 3. Observing with your senses • Color – you use your sense of sight to observe color • Iron & copper are both metals. • Iron is dark gray, copper is orangish brown. • Color helps tell them apart
  4. 4. Observing with your senses • Texture – the way a surface feels, smooth vs. rough, using your sense of touch. • Some surfaces are smooth, waxy, grainy, soft, powdery, grea sy.
  5. 5. Observing with your senses • You can also use senses of hearing, smell, and taste to observe physical properties. (Don’t use taste unless safe to do so) • Sugar and salt look similar, taste helps tell them apart.
  6. 6. Observing with your senses • Some properties describe how a substance acts. • Conductor – conducts or transfers heat • A good conductor lets heat pass through it easily.
  7. 7. Observing with your senses • Metals such as copper, silver, and iron conduct heat well • Plastic, wood, rubber, and glass are not good conductors. • Many substances that conduct heat also conduct electricity well.
  8. 8. Observing with your senses • Magnetism is another observable act. • You can also observe whether a substance dissolves in water. • To dissolve means to mix evenly into a liquid, when it dissolves it breaks into tiny pieces and seems to dissappear
  9. 9. Observing with your senses • Sugar and salt dissolve well. • If you stir sand in water it does not dissolve well.
  10. 10. Observing with your senses • A substances state of matter can also be observed. • Heating or cooling can cause it to change from one state to another • ice – water – water vapor
