Today in science class, we learned about different types of separation. First we did an experiment using felt pens to see what colours makes it up.
this is an example of what we did
when the water is absorbed in the paper, the different colours that makes up the ink appears. This is called Chromatography Separation.
Second, we did filtration. We separated iron and water mixed together.
we folded the filter paper into more sections so the water would be separated faster.
folding the filter paper.
By using a funnel and an erlenmayer flask, we separated water from the iron bits.
This method is called Filtration
Third, we tried to separate sulphur and iron by using magnets.
Iron is magnetic, therefore the magnet can attract the iron while leaving sulphur out.
This is a common used separation to separate metal scraps.
this is an example of magnets separating iron from sawdusts.
The method is called magnetic separation.
Fourth, we talked about sewage treatments, how the sewage settles down while the water floats up.
Last, we also discussed about the separation of gas and water in oil tanks that are in cars. Also like in salad dressings where the oil separates from water.
