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

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…

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….
