You have a mixture of sand, salt, and iron filings. What steps would you take to separate each substance using different methods?

1) Use a magnet to remove the iron filings. 2) Pour water into the salt and sand mixture. 3) Use filtration to remove the sand. 4) Evaporate the water to retrieve the salt.

You have a mixture of dirt, sugar, and woodchips. Describe a step-by-step plan to completely separate all four substances.  

1. Manually take out the woodchips

2. Pour water into the dirt and sugar mixture

3. Run the mixture through a filtration system

4. Evaporate the water to be left with the sugar

After a storm, a homeowner’s backyard pond has become polluted with dirt, leaves, and small pieces of metal debris from a nearby construction site. What separation techniques should they use to clean the pond, and in what order?

1. Manual Separation – Large leaves and debris can be removed by hand or with a net.

2. Magnetism – A magnet can be used to pull out any small metal pieces from the water.

3. Filtration – A filter can be used to trap small dirt particles while allowing clean water to pass through.

Metal vs Nonmetal

100

Is very shinny 

Metal

200

S on the periodic table

Nonmetal because sulfur is brittle, does not conduct, and is not shinny

300

Cu on the periodic table

Metal because copper is shinny, malleable, and conducts electricity. 

400

Is a poor conductor and is brittle

Nonmetal

500

Is found as a solid, liquid, or gas, at room temperature 

Nonmetal
