  • Identify the states of matter in the beakers above:
    Beaker 1 - Solid 
    Beaker 2 - Liquid 
    Beaker 3 - Gas
  • Draw a diagram showing how to change the state between ice, water and water vapour.
    CONDENSATION
    gas => liquid
    EVAPOURATION
    liquid => gas
    DEPOSITATION
    gas => solid
    SUBLIMINATION
    solid => gas
    SOLIDYING
    liquid => solid
    MELTING
    solid => water
  • PROPERTIES OF MATTER
    Volume - The amount of space an object occupies
  • PROPERTIES OF MATTER
    Density - How close particles are to each other
  • PROPERTIES OF MATTER
    Melting point - the temperature when a solid turn into a liquid
  • PROPERTIES OF MATTER
    Boiling Point - The temperature when the liquid starts turning into gas
  • PROPERTIES OF MATTER
    Diffusion - Movement of particles from a region of high concentration to a region of lower concentration
  • PROPERTIES OF MATTER
    Kinetic Energy - Moving energy for the particles
  • How does the kinetic energy, forces of attraction, and space between particles change as you go from a gas to a liquid?
    • The kinetic energy of the particles decreases, the forces of attraction between the particles increase and the space between the particles decreases. 
  • the difference between thermal expansion and thermal contraction?
    • Thermal expansion is when an object expands when the temperature increases.
    • Thermal contraction is when an object shrinks when the temperature decreases. 
  • tūpuna meaning?
    An ancestor, or a grandparent.
  • What are toki?
    • Toki is a chisel-type tool used among the maori to carve their great canoes and hui houses, it is worn by maori elders as a symbol of courage, power, and authority.
  • HOW IS TOKI CREATED?
    • When the rock is heated with fire, particles of the rock begin to vibrate as there is more kinetic energy, causing it to spread out more. When the rock is being cooled at a fast pace, this makes the kinetic energy less, and having the particles vibrate less. Closing up the space between them, so the rock contracts. 
    • The outer part of the rock cools down before the inner part of the rock, causing the rock to shatter. The shattered pieces can be used to craft toki.
  • FORMULA FOR DENSITY
    FORMULA - p = M/V (density = mass / volume)
  • Symbol names
    _______________________
    Atomic number => A.N
    atomic mass => A.M
    proton => p
    neutron => N
    electron => E
  • Properties of metals
    • Lustre (shiny)
    • sonorous (makes a sound)
    • ductiles (makes wire)
    • conductor (electricity/heal)
    • malleable (beaten into shape)
  • Write the names of the following elements:
    Ca  calcium
    K   potassium
    Na sodium
    Li  lithium
    carbon
    oxygen
  • The equation for burning fuel
    Fuel + oxygencarbon dioxide + water
  • G = GIVEN U= UNKNOWN E=EQUATION S=SUBSTITUTE S= SOLVE
