Content Vocabulary:

• Gas – a state of matter in which the substance expands to take both the shape and the volume of its container
• Graduated cylinder – a container with measured markings used to measure volume of liquids
• Liquid – take the shape of their container, filling the bottom of the container first; has the ability to flow
• Magnetism – a force of attraction that causes a magnetic material to move
• Mass – the amount of matter in something
• Matter – a substance that has mass and takes up space
• Metric system – the decimal measuring system based on the meter, liter, and gram as units of length, volume (capacity), and weight or mass
• Physical property – a property that can be observed, measured, or changed without changing the matter itself
• Solid – definite shape and size
• States of matter – the forms matter can take, such as solid, liquid, and gas; sometimes called phases of matter
• Temperature – a way of measuring how hot or cold something is; temperature is measured using either the Fahrenheit (F) or Celsius (C) scale
• Triple beam balance – a toolused to measure masses very precisely
• Volume – the amount of space that a substance or object takes up

PHYSICAL PROPERTIES OF MATTER

• Size (larger and smaller)
• Mass – the amount of matter in something
• Volume – the amount of space that a substance or object takes up
• Physical states (solids, liquids, gases)
  • Solids
    • Definite shape and size
    • Do not take the shape of their containers
    • Note: Some solids may appear to flow when particles are very small (e.g., flour, sugar, salt)
  • Liquids
    • Take the shape of their containers, filling the bottom of the container first (e.g., water filling the bottom of a cup)
    • Ability to flow
  • Gases
    • Expand to take the shape of their containers
    • May escape when container is opened (e.g., air escaping from a balloon)
  • Temperature (a way of measuring how hot or cold something is)
    • Temperature is measured using either the Fahrenheit (F) or Celsius (C) scale
• Magnetism – a force of attraction that causes a magnetic material to move
  • Magnet – an object that attracts (pulls) iron and a few other magnetic materials, such as nickel and cobalt; can push or pull objects
• Ability to sink or float in water
