Science - Properties Of Everyday Materials - 5.03.15

1. School Direct Trainee
Twilight
Properties of Everyday
materials

2. Using your iPad scan this QR code…
And follow the instructions…

3. 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

4. What the PoS says
Year 1

5. What the PoS says
Year 2

6. Practical's where we can
test properties
Melting and Boiling point
Practice measuring

7. Practical's where we can
test properties
Transparency
Introduce a bit of cognitive
conflict, can things be opaque
and translucent?

8. Practical's where we can
test properties
Solubility
Sugar vs Salt
Maybe involve temperature?

9. Practical's where we can
test properties
Conductivity
Both heat and temperature (they
work for the same reason)

10. Practical's where we can
test properties
Magnetism
Testing is something is Magnetic
is easy… What about testing if
something is a Magnet?

11. Researching Scientists
There are 5 scientists named in the PoS for this
aspect of science…
John McAdam
John Dunlop
Charles MacIntosh
Spencer Silver
Ruth Benerito
Use Adobe Voice or
Animoto to teach us about
them

12. What the PoS says
Year 4

13. What the PoS says
Year 5

14. Practical's where we can
test changing properties
Changes of State
Linking 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

15. Practical's where we can
test changing properties
Salt in water
Challenge thinking by adding salt to ice and
measuring the change in temperature…

16. Practical's where we can
exploit changing properties
Get the Salt back
A harder separation technique but gets
students thinking about exploiting
properties to change materials back…

17. Practical's where we can
exploit changing properties
Simply by size
Filtration is basically the same as sieving,
except the holes are smaller…

18. Practical's where we can
exploit changing properties
Separating by properties
Separating by taking advantages of physical
properties… Dissolving and Magnetism are
good examples…

19. 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)

20. 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

21. 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

22. Sparklers & Fireworks….
