How are mixtures separated?

Hey there!

We continue with the science lessons

On Monday we saw that if we mix two or more elements we get a mixture. Today, we are going to learn how we can separate them.

First listen the audios.

Page 11

We have four kinds of separations depending on the elements of the mixture.

Filtration: Heterogeneous mixture made up of a solid and a liquid. Like soil and water.
Evaporation: Homogeneous mixture made up of a solid and a liquid. Like salt and water.
Distillation: Homogeneous mixture made up of two liquids. Like alcohol and water.
Dissolution: Mixture made up of two solid, one soluble and one insoluble. Like soil and salt

There's another separation way that is important to know
Decantation: Heterogenous mixture made up of two liquids. Like oil and water.




Homework: Let's investigate.
Today I recommend you to make exercise number 4 of page 11, is a experiment that you could do at home.
