To find the metals volume you have to get a graduated cylinder and drop the metal in the water make sure the liquid in the beaker is filled to at least 30mL. Read the graduated cylinders measurement after dropping the metal in the liquid, which is the volume. Repeat this step for each medal.

Sludge is a mixture of liquids, plastics, metals and non metals. We are trying to find what is inside of sludge.

To find the mass of the liquid you have to fill the graduated cylinder up with the liquid, then put it in on the scale. Take that mass and subtract the mass of just the mass of the graduated cylinder.

To do the solubility test you get sugar and put it in the liquid. If the liquid is soluble to the sugar it will dissolve, and if it doesn't dissolve its insoluble.

You are trying to figure out what the substance of the liquid is. To identify this liquid you have to find the boiling point, we heat till we collect enough condensation to make a new clear liquid.

For the medal test you are trying to find density of a metal, you have to take the mass of the metal then find the volume. To find the volume you find the density of the metal then divide it by the mass of the metal. So you would then take the mass divide it by the volume to get the density.

Density is Mass divided Volume.

For the liquid test you need to smell for odor, you need to find the density, the boiling point, flammability, and solubility of sugar.

# data[].attributes.body
Odor-lends itself to purity
Density- mass divided by volume
Boiling Point-take temp reading every 30 sec until a plateau of 6 readings the same or close to dryness
Flamibility-Dip splint in liquid and pass through the flame
Solubility of Sugar- add small amount of sugar (ask yourself: does it dissolve?)

# data[].attributes.body
-Solubility in Water
-Solubility in Alcohol
-Micro Melting Point
-Reaction with Acid
-Evaporating Dish Melting Point

# data[].attributes.body
- See if it has a magnetic reaction
-weigh it
-find its density

# data[].attributes.body
-to help you find out what type of metal it is you can do the acid test.
- you place a few droplets of acid on the medal and watch to see if there is a reaction or not.
-Use Hydrochloric acid
