6. SEPARATING MIXTURES using theSEPARATING MIXTURES using the
scientific methodscientific method
Our aim was separate the different
ingredients of a mixture using three
methods:
- Filtration
- Magnetism
- Evaporation
How we did it?

7. 1st.- We mixed some salt,
some soil and some iron
filings.

8. 2nd.- We separated iron filings
from the mixture by …
MAGNETISM
Magnet atracts the iron filings. It was amazing!!

9. 3rd.- Then we add
some water to make a
new mixture:
water, soil and salt.
Salt is dissolved in
water

10. 4 rd.- .- We separated soil
from waterand salt by
FILTRATION
Water passed through the
filter and the soil remained
in it.

11. 5 th.- We put the
solution in a dish.
6 th.- All the dishes
with the solutions were
placed on the radiator.

12. 7 th.- We waited 24 hours, and …
A cause the heat, water was
disapperared!
Salt have made chrystals!

13. The discovery was amazing forThe discovery was amazing for
students.students.
We recorded all the
process in our lab
worksheet.

14. 8 th.- .- We separated salt
from water by
EVAPORATION
