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
- Solids
- 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
