4000 CHEMICALS DEMONSTRATION This is an excellent demonstration to use with the class. ACTIVITY: 4000 CHEMICALS This is 15-20 minute activity to visually demonstrate to the students some of the toxic ingredients within cigarettes. MATERIALS you will need to gather in advance: BATTERIES have cadmium CLEANSER CONTAINING AMMONIA has ammonia NAIL POLISH REMOVER has acetone VINEGAR has acetic acid LIGHTER has butane PURE DENATURED ALCOHOL has ethanol (Found in products such as varnish -- find in hardware stores) INSECTICIDE has DDT CANDLE WAX has stearic acid JAR OF MOLASSES W/O THE LABEL represents tar SMALL TOY CAR represents carbon monoxide Label each of the items with the representative toxic ingredient. Have a listing of all the chemicals found in tobacco and talk about the ones known to cause cancer. (The resource “What’s in Cigarette Smoke” will provide this list.) Talk about the poisons such as arsenic and cyanide that are in cigarettes. Also talk about formaldehyde, which is used to preserve dead bodies. Give them a moment to think about these chemicals actually being in cigarettes and that people smoke them. Now pick up each one of the samples you have labeled and talk about them. Vinegar: the main ingredient in vinegar is acetic acid. Why would you want to smoke something like this? When you think of vinegar you think of salad dressing. Lighter: Cigarettes contain butane, which is the fluid in this lighter. Denatured Alcohol: There is a skull and crossbones on this bottle to indicate that it contains poison. You wouldn’t drink it. So why would someone smoke it? Insecticide: There’s DDT in cigarettes and this is what is in insecticide to kill bugs. Just imagine what smoking is doing to a person’s insides? Candle: Stearic acid is in candle wax, also in soap, cocoa butter, lotions and other lubricants. Nail Polish remover has acetone in it to take off nail polish and it’s in cigarettes Cleanser: The smell of ammonia can make you sick, just imagine inhaling it Batteries: cadmium is found in batteries, a mineral that can damage lungs, stomach, liver and kidneys Molasses to represent the tar—visualize tar that is used to fix a roof and that’s what’s in the cigarette. Toy car: The tailpipe on a vehicle releases CO2 and so does the cigarette. CO2 stays in a smoker’s blood up to six hours. Follow up by leading a discussion: Do you think people who smoke know what’s in the cigarette? If they’ve been told then how come they still smoke?
