The 6 types of plastics:
1. PET (polyethylene terephthalate)
2. HDPE (high density polyethylene)
3. PVC (polyvinyl chloride)
4. LDPE (low density polyethylene)
5. PP (polypropylene)
6. PS (polystyrene)
Tests you can use:
1. Copper Wire Test (The flame will turn green)
2. Acetone Test (Does the plastic have a reaction)
3. Heat Test (Rolling boil and see if the plastic will sink or float)
4. Isopropyl Alcohol Test (See if plastic will sink or float
5. Oil Test (See if plastic sinks or floats)

During the acid test you are supposed to place the substance you are testing onto the watch glass. Drop a drop of acid onto the substance and then see if it has a chemical reaction.

During fractional distillation you want to separate two pure liquids from one another.

There is supposed to be a picture of an evaporating dish demonstration. Click on it.

When you use an evaporating dish you want to make sure that you DON'T TOUCH IT WITHOUT GLOVES ON!!!!! Your goal is to separate two substances. for example say you are going to separate salt and pepper. Salt dissolves into water while pepper does not. You would first put the mixture into the filter paper and funnel and wait for the pepper to come out. Then you take the salt water and pour it into the evaporating dish. Then you will evaporate the water out until it is just the salt left.

To find the density of a a solid you must divide the mass and the volume. Use the equation d=m/v. Don't forget to use the units g/cm3 at the end of your final answer.

This picture shows what to do when you are trying to solve for mass. In this case you are finding the mass of the nail. Remember to use the unit for mass which is grams or g.

This is a demonstration on how to find the volume of an object. In this case the nail is the object that you are trying to find the volume of. Remember to use the units for volume which are cm3 or ml.

To find the volume of a irregular solid (any solid that isn't in a cube) you must first fill up the empty Graduated Cylinder to 5-10 ml (sometimes the amount may differ depending on the liquid that is being used). Then add the solid into the liquid an record the volume that is received. To find the mass of a solid you must place the solid onto the balance and then find the weight on the screen. You want to do this before you find the volume!! For both of these don't forget to use the units g for mass and cm3 or ml for volume!!!

The boiling point of a liquid is when a liquid turns into a gas. To find it you must heat a liquid until it begins to evaporate or boil. Don't forget to use boiling chips. The micro melting point of a powder is when you put the powder into a capillary tube and attach it to the handheld thermometer. Place the thermometer and the capillary tube into a beaker filled with 100ml of water and heat until the powder has melted.

Sludge to me is a mixture of liquids, plastics, powders, and metals which takes up to three days to identify.
