Separation of Mixtures

What is a mixture made up of?

• two or more substances
• one substance
• always only two substances

How does filtration separate a mixture?

• by separating with your hands
• by evaporating
• by running the mixture through a filter and removing a solid from a  liquid
• pouring off

How does evaporation separate a mixture?

• pouring the mixture through a filter
• evaporating the liquid part of the solution, leaving the solid part behind
• separating materials by hand
• pouring off

How does sorting separate a mixture?

• by boiling the mixture until only the solid part is left
• filtering
• pouring off
• separating two materials by hand based on physical properties

How does pouring off separate a mixture?

• separating materials by hand based on physical properties
• filtering
• the liquid on top is carefully poured off into a different container.  The liquid is left behind.
• evaporating the liquid so the solid is all that is left

How does sifting separate a mixture?

• It is a form of filtering solids from one another based on particle size.
• pouring off, leaving the liquid
• boiling, leaving only the solid
• separating by hand by physical properties

What is an example of separating using magnetism?

• making coffee
• separating different colored jelly beans
• separating sand from rocks on the river bank
• separating sand and iron fillings

How can you use settling to separate a mixture?

• filtering, such as making coffee
• sifting through the liquids
• solid particles float in a liquid by allowing heavier particles to settle to the bottom
• boiling, leaving only the solid behind

What is an example of separating a mixture by evaporation?

• separating salt and water
• separating oil and water
• separating sand and rocks
• separating by hand by physical characteristics

What would be an example of using sorting to separate a mixture?

• making coffee
• separating sand and water
• separating jelly beans by color
