Filtration: The process of passing a liquid or gas through a filter in order

to ­­_________________________________________________.

Filtration can be used to separate a mixture. Some parts of the mixture will

 go through the filter, some will be _________________________________.

How is filtration a physical change? __________________________________.

Distillation: the process of separating a liquid by boiling it and

condensing ___________________________.

Boiling Point: The temperature at which a liquid boils and turns

_____________________________________

Freezing Point: The temperature at which a liquid turns

__________________________________

Liquids with different boiling points can be separated by

their _________________________

The liquid with the lower boiling point is called the

_____________.

How is distillation is a physical change?

Questions:

1.If I gave you a mixture of three different liquids and didn’t tell you what they were how  

could you use distillation to help you figure out what they were?

2. If I gave you a mixture of 3 different liquids, and did not tell you what they were, how could you use

density to figure out what they were?

3. If I gave you a mixture with solids in it, how could you use filtration to separate the mixture?

 Mini Poster Assignment

 

LT:  I can describe how filtration, density and distillation can help separate a mixture.

Mini Posters Assignment

Step 1: Using the rubric, students will make mini posters about one of the separation techniques, and describe how it would help separate a mixture.

Step 2: Students will then present their mini-poster to the class.

Ms. Mac will assign each table group a separation technique.

My separation technique is: ______________________________

Describe how your separation technique helps separate a mixture

o   Describe ALL of the steps and or process you would use to separate a mixture using your technique.

Example: I would use density to help me separate a mixture by first….

o   Describe how your separate technique is a physical change (Use your notes)

o   Draw a picture of your separate technique

o   Label the picture of your separation technique.
