1 DUI Stations Station 1: Introduction to alcohol chemistry Introduction: Molecules of alcohols, aldehydes and organic acids all have characteristic functional groups. Functional groups are groups of a few atoms that impart distinctive physical and chemical properties to organic compounds. Alcohols, aldehydes and organic acids have common names and International Union of Pure and Applied Chemistry (IUPAC) names. Chemists prefer the IUPAC name for compounds because it is systematic as well as easily adaptable to new compounds. Atoms, bonds and molecules can be represented in various ways. Each method has its advantages and drawbacks. Molecules can be represented by condensed structural formulas and structural formulas. Alcohol and other toxins are broken down to different metabolites in the body. Alcohol is broken down to a substance called an aldehyde and then ultimately becomes a carboxylic acid. Do some research to fill in the chemistry table. Some examples have been completed for you: IUPAC name Methanol Methanal Methanoic acid Common name Formic Acid Chemical formula CH 3 OH Structural formula IUPAC name Ethanol Ethanal Ethanoic acid Common name acetaldehyde Chemical formula Structural formula What do you notice about the two alcohols-methanol and ethanol? 1

2 Station 2: Introduction to alcohol chemistry questions-use your table or do research to find: 1. What are the functional groups of alcohols? 2. What are the functional groups of aldehydes? 3. What are the functional groups of organic or carboxylic acids? Identify the functional group in each of the following molecules-circle and then name: A) CH 3 OH B) CH 3 CHO C) CH 3 COOH D)CH 3 CH 2 OH E) H 2 CO F) HCOOH 4. Write the IUPAC name for each of the following molecules: A) CH 3 OH B) CH 3 CHO C) CH 3 COOH D) CH 3 CH 2 OH E) HCHO F) HCOOH 2

3 5. One way to recognize organic oxidation is to compare the carbon containing compound before oxidation to the carbon containing compound that results from the oxidaton. If there is a loss of hydrogen or the addition of oxygen to the product, then oxidation has occurred. A) When ethanol is metabolized to ethanal, oxidation occurs. Provide evidence to verify this statement. B) When ethanal is metabolized to ethanoic acid, does oxidation occur? Provide evidence to support your answer. 3

4 Station 3: Drinking goggles Instructions: While wearing the obscured goggles or sunglasses write down the following sentences on the poster paper provided: Why, sir, for my part I say the gentleman had drunk himself out of his five senses. O thou invisible spirit of wine! If thou hast no name to be known by, let us call thee devil! 4

5 Station 4: Nystagmus test Instructions: 1) Watch the following video and then explain nystagmus: 2) Take one of the pen lights available and use it to check pupils of a partner s eyes to see if they are dilated. Indicate Yes or No: 3) Shine the light into your partner's eyes with their permission and watch how their pupils change shape. If they had been drinking, their pupils would stay dilated. 4) Move the light around in several directions in front of partner s eyes and have your partner follow the light with the eyes only (not moving their head). If the person had been drinking they would not be able to focus on the light or any object. 5

6 Station 5: Walk the line Instructions: The fourth station will have a 3 inch wide, 10 feet long tape taped on the floor. Have one partner put hands and palms together and, while standing, raise the hands straight up above the head. While looking directly up at the hands, the other partner will help the first spin around five or six times. Immediately following this, the person who was spinning is to try to walk in a straight line along the tape in a heel to toe fashion! Then have partner stand with one foot raised about 6 inches off ground and count for 30 seconds. 6

7 Station 6: DUI Marijuana Instructions: Watch the following videos and look through the associated articles to help answer the questions about DUI: 1) Explain at least 3 reasons for differences between drug standards and alcohol DUI standards: 2) What chemical is found in blood after marijuana use? 3) Where are the metabolites of marijuana stored in the body? 4) How long can marijuana traces remain in the body after ingestion? 5) In 2014, what did the Arizona Supreme Court rule about the per se marijuana DUI law? Specifically which chemical does it pertain to? Station 7: DUI stop Instructions: Check out this article to explain the 3 phases of a DUI stop: Now work with a partner to come up with a DUI stop skit that is at least 4-5 minutes in duration-what will the suspect be doing to rise suspicion? What questions and behaviors should the officer be performing? 7
