  2. The three forms that matter usually takes: solid, liquid, and gas.

  3. states of matter The three forms that matter usually takes: solid, liquid, and gas.

  4. A single particle of matter made up of two or more atoms joined together.

  5. Molecule A single particle of matter made up of two or more atoms joined together.

  6. A change in the size, shape, or state of matter that does not change it into a new kind of matter.

  7. physical change • A change in the size, shape, or state of matter that does not change it into a new kind of matter.

  8. Material that an electrical charge can move through easily

  9. Conductors Material that an electrical charge can move through easily
