Separation of mixtures

We are studying the characteristics of mixtures in our Scienglish lessons with Jakub, a teacher from the Czech Republic.

After learning the components in some mixtures like stones, sand, salt, water and iron filings, we know how we can separate each one from the others.

For example:

* if we have a mixture of salt and water, we can evaporate the water and we get pure salt.

* if we have a mixture of stones and sand, we can pick the stones by hands and we get pure sand.

* if we have a mixture of water and sand, we can use a funnel and a filter paper and we get pure water.

* if we have a mixture of sand and iron filings, we can use a magnet and we get pure sand.

We work in teams and we participate in all the lessons we attend.
