This is the beginning of the lesson.

  • Matter is made up of tiny particles (Atoms & Molecules)
  • Particles of Matter are in constant motion.
  • Particles of Matter are held together by very strong electric forces
  • There are empty spaces between the particles of matter that are very large compared to the particles themselves.
  • Each substance has unique particles that are different from the particles of other substances
  • Temperature affects the speed of the particles. The higher the temperature, the faster the speed of the particles.
  • All matter is consists of many very small particles which are always moving or in a repeating state of motion.
