Separating a Mechanical Mixture

 Problem- Separate a mechanical mixture.

Safety precautions- safety goggles and   apron

 

Material and apparatus 

2 Beakers

 

 

 

Funnel

 

 

 

Magnet

 

Stirring Rod

 

Sand

 

 

 

 

 

 

 

 

 

 

 

 

Salt
Iron fillings

 

 

Procedure:

Step 1- Half fill a 250ml beaker with the mixture

 

 

 

 

 

 

 

 

 

 

Step 2- Pour the mixture onto the paper

 

 

 

Step 3- Move the magnet over the surface of the mixture several times.

 

 

 

 

 

 

 

 

 

Step 4- Pour the mixture back into the beaker

 

Step 5- Add 100 ml of water to the beaker and stir until you can not see any sugar crystals
Step 6- Filter the from Step 5.

 

 

Step 6- The water is still dirty in the filter

 

 

Step 7- Cleaning the area used for the experiment

 

 

 Predictions: 

 

I thought the filter would get dirty and the water wouldn’t change.  

 

OBSERVATION:  

 

  • Dirty, brown water; grass floating; swirling liquid; sand at the bottom of beaker

       

 

CONCLUSION:

 

In this experiment, the filtering of the dirty water made the water less dirty. 

I learned that dirty water could be filtered to be kind of clean again. I might not ever need to use this information but it was cool to learn.

 

What did you find out: 

  1. The water got dirty, The filter caught the grass. 
  2. We could see multiple things in a mixture and a filter will separate some of these things.
