Properties of Everyday materials
Using your iPad scan this QR code…
And follow the instructions…
Grouping Materials
Take the materials provided and group them in as many different ways as possible…
Take a picture of every different way you choose to group the materials
Write next to the groups what your criteria is in each case
What the PoS saysYear 1
What the PoS saysYear 2
Practical's where we can test properties
Melting and Boiling pointPractice measuring
Practical's where we can test properties
TransparencyIntroduce a bit of cognitive conflict, can things be opaque and translucent?
Practical's where we can test properties
SolubilitySugar vs SaltMaybe involve temperature?
Practical's where we can test properties
ConductivityBoth heat and temperature (they work for the same reason)
Practical's where we can test properties
MagnetismTesting is something is Magnetic is easy… What about testing if something is a Magnet?
Researching ScientistsThere are 5 scientists named in the PoS for this aspect of science…
John McAdamJohn DunlopCharles MacIntoshSpencer SilverRuth Benerito
Use Adobe Voice or Animoto to teach us about them
What the PoS saysYear 4
What the PoS saysYear 5
Practical's where we can test changing
propertiesChanges of StateLinking properties of materials to changes of state…When you melt the ice how does it change?Evaporation doesn’t mean it disappears, hold a mirror above a boiling kettle
Practical's where we can test changing
propertiesSalt in waterChallenge thinking by adding salt to ice and measuring the change in temperature…
Practical's where we can exploit changing
propertiesGet the Salt backA harder separation technique but gets students thinking about exploiting properties to change materials back…
Practical's where we can exploit changing
propertiesSimply by sizeFiltration is basically the same as sieving, except the holes are smaller…
Practical's where we can exploit changing
propertiesSeparating by propertiesSeparating by taking advantages of physical properties… Dissolving and Magnetism are good examples…
Avoid chemical Changes till Year 5…
“Something new is made that’s really hard to change back”Chemical changes required are simple…
Combustion
Link to the fire triangle here (Oxygen can be easily removed)
Avoid chemical Changes till Year 5…
“Something new is made that’s really hard to change back”Chemical changes required are simple…
Vinegar and Bicarbonate of Soda
Bubbles because CO2 is made
Avoid chemical Changes till Year 5…
“Something new is made that’s really hard to change back”Chemical changes required are simple…
Rusting… put in salty water to speed this process up
You could link this to rust protection, using Oil or nail varnish to protect the metal
Sparklers & Fireworks….
