  • The wood is receiving thermal energy from the fire. What will happen?
    It will change state, from wood to ashes
  • When water turns into a solid,- ice - this is called (melting, evaporation, condensation or freezing)
    Freezing
  • Everything around us is made of ________
    Matter
  • Solid, liquid or gas? It doesn't have a definite shape or volume
    Gas
  • In a mixture, to separate a solid from a liquid that it is DISSOLVED in we do this (sieve, filter, evaporate)
    evaporate
  • When water vapour cools, it turns liquid. This is called (melting, evaporation, condensation, freezing)
    condensation
  • Name 2 or 3 materials that are good insulators
    Wood, wool, plastic
  • In a mixture, to separate solids of different sizes we do this (sieve, filter, evaporate)
    sieve
  • This type of energy travels in waves
    Sound energy
  • Solid, liquid or gas? It has a definite shape AND definite volume
    Solid
  • In a mixture, to separate solids from liquids we do this (sieve, filter, evaporate)
    filter
  • Thermal energy passes through ____(conductors/insulators) quickly
    Conductors
  • True or false: thermal energy passes through insulators quickly.
    FALSE. Thermal energy passes through insulators very slowly.
  • True or false: matter does not change state
    False, it can change from one state to another
  • A mixture is made up of how many materials?
    More than one
  • Solid, liquid or gas? It doesn't have a definite shape, but it does have a definite volume
    liquid
  • If we heat water, it changes into a gas called water vapour. This is called (melting, evaporation, condensation or freezing)
    evaporation
  • Electrical energy can be changed into other types of energy, such as ___
    light energy, sound energy, thermal energy, kinetic energy
  • What types of energy does the sun produce?
    Thermal energy and light energy
  • True or false: you can always see the different materials in mixtures
    False, sometimes you can see the different materials, but sometimes you can't
  • Which is the odd one out (different)? Juice, milk, chocolate. Explain your answer
    Chocolate because it is a solid and the others are liquid
  • True or false: we can separate all mixtures
    False, we can separate some but not all
  • True or false: one form of energy CANNOT change into another form
    False, energy CAN change from one form to another
  • What are the three states of matter?
    Solid, liquid and gas
  • If we heat ice, it changes back into a liquid. This is called ___ (melting, evaporation, condensation or freezing)
    Melting
  • We use this type of energy to make machines work
    Electrical energy
  • Anything that moves has this type of energy
    Kinetic energy
  • Water can be found in three states. What are they?
    Ice (solid), water (liquid) and water vapour (gas)
  • Metals are good ____ (conductors/insulators)
    conductors
