Solid, Liquid & Gas Properties

  1. 1. Solid, liquid or gas? Tick the correct box to show whether each material is a solid, liquid or gas. Material Solid Liquid Gas Air Toothpaste Jam Steam Paper Water Salt Coca-Cola Milk
  2. 2. Solid, liquid & gas properties  Underline the properties of solids.  Circle the properties of liquids.  Draw clouds round the properties of gases. You will mark some phrases more than once. flow easily do not flow easily easy to compress difficult to compress (squash) bad heat conductors often good heat conductors high density low density keep their shape take their container’s shape diffuse (spread out) do not diffuse (spread out)
  3. 3. Circus of experiments  Experiment 1 Comparing the masses of different materials  Measure the masses of the blocks.  Record and explain your results. Experiment 2 Putting a coloured crystal into warm water  Use forceps to pick up a purple crystal.  Drop it in the water.  Record and explain your observations. Experiment 3 Heating a metal bar  Try to put the metal bar in the hole.  Heat the metal bar and try to put it in the hole again.  Record and explain your observations. Experiment 4 Pressing the plungers on three syringes  Try pressing the plungers on the syringes. How easy is it to squash (compress) the materials?  Record and explain your observations. Experiment 5 Adding small weights to a thin wire Put on eye protection.  Add weights to the wire. What happens to its length?  Record and explain your observations. Experiment 6 Opening a perfume bottle  Take the lid off the perfume.  Record and explain your observations.
  4. 4. Explaining the evidence – 1 Experiment 1 Wood Glass Metal Mass of block (g) The ___________ block is heaviest. My explanation: ___________________________________ _______________________________________________ Experiment 2 When I put the purple crystal in water I saw ____________ _______________________________________________ My explanation: ___________________________________ _______________________________________________ Experiment 3 The metal bar did/did not go through the hole when it was cold. It did/did not go through the hole when it was hot. My explanation: ___________________________________ _______________________________________________
  5. 5. Explaining the evidence – 2 Experiment 4 Material How easy Explanation was it to squash? Air Water Sand Experiment 5 When I put weights on the wire, the wire got _____________ and _____________. My explanation: ___________________________________ _______________________________________________ Experiment 6 When I opened the perfume, I _______________________ _______________________________________________ My explanation: ___________________________________ _______________________________________________
