• It's All in the Blood - The problem of converting a hospital blood test for alcohol into the legal units is based on the various components of the blood, particularly the blood serum.
  
  
• The PBT as Legal Evidence of Impairment - A police officer demonstrates the hand-held breath test device used to do a “preliminary breath test”.
  
  
• “I Only Had Two Beers” - Students research the ethanol content of popular brands of beer to show how different brands can cause differing degrees of intoxication.
  
  
• Under the Limit, But Seriously Impaired - Students research the effects of alcohol at levels below the legally defined level of assumed intoxication to find that many driving skills are impaired at low BAC levels.
  
  
• Newton Would Have Worn a Seat Belt! - Students analyze video footage of a real crash to determine why the belted driver survives the violent rear-end collision.
  
  
• Skateboards and Cars Don't Mix - Students measure the speed of a skateboarder and then determine if an accident is avoidable if the skateboarder goes out into the street from a driveway.
  
  
• People Can't Fly - And They Don't Land Well Either - Students look at the energy that must be absorbed to avoid an injury and the importance of staying inside the car.
  
  
• Kinetic Energy and Insurance Fraud - Students determine whether a witness statement about speed is true, and how the truthfulness of the statement uncovers a fraudulent insurance claim for personal injuries.
  
  
• Projectile Motion - Impact Speed in a Fatal Crash - Students analyze police evidence and determine the speed of a motorcycle involved in a fatal crash.
  
  
• Linear Momentum Takes the Witness Stand - Students look at the certainty of police testimony in a DWI homicide case by applying a momentum calculation to the crash evidence.
  
  
• Distractions Can Be Deadly ! - Students measure the distraction caused in typical situations and the consequences of being inattentive.
  
  
• Observing Impairment in Driving Tests - Students make observations of drivers who are given alcoholic beverages and then perform driving maneuvers in a controlled driving test to pick out the classic symptoms of alcohol impairment.
  
  
• Measuring Road Friction with a Police Drag Sled - Includes calculations of stopping distances, following too closely, etc. as it relates to the coefficient of friction of the roadway.
  
  
• Projectile Motion in Accident Reconstruction - Examples of projectile motion equations related to pedestrian collisions, vaulting from the roadway, etc., including uncertainty considerations.
  
  
• Weighing a Car with a Bath Scale - Applications of torques to a hands-on problem.
  
  
• Reconstructing a Murder by Automobile - Working with an actual police report students reconstruct speed using conservation of energy; includes a video animation used at trial.
  
  
• Reconstructing a Vehicle-Motorcycle Crash - Using conservation of energy students reconstruct the speed of the motorcycle to determine liability.
  
  
• Parametric Equations and Tractor Trailer Speed - By algebraic simplification the equations of motion are used to determine tractor trailer speed from tire marks on the roadway.
  
  
• Using Linear Momentum in Accident Reconstruction - Students determine speed, including use of a spreadsheet analysis to show the certainty of the conclusion. Ideal for computer classes.
  
  
• Quadratic Equations in Accident Reconstruction - Students see the general quadratic equation applied to pedestrian throw distance, debris rest position in a crash, etc.
  
  
• Vehicle and Occupant Kinematics - Newton's First Law applied to injury mechanisms in cars.
  
  
• How Do Crumple Zones Save Lives? - Newton's Second Law applied to preventing injuries.
  
  
• Newton's Laws in the Courtroom - Actual police files (2 different cases) on intersection collisions - students use Newton's Laws to determine who was at fault.
  
  
• Examining Lamps for ON/OFF - Students determine, by applying Newton's Laws, whether a lamp was on or off at the moment of impact; includes lamps and magnifiers.
  
  
• Using an Autopsy Report to Determine Who Was Driving - Biology students map injuries to determine if the person was a passenger or driver - ideal for anatomy studies.
  
  
• Investigating a MV Homicide - Students design questions to ask of witnesses, what physical evidence to document, photographs to take, etc. Develops critical thinking skills.
  
  
• Was It Safe to Cross? - By using equations of motion, students measure pedestrian walking speeds and are able to see how far away a car must be to allow safe crossing.
  
  
• Determining Whether a Vehicle Ran a Stop Sign - Students measure vehicle acceleration to determine whether a vehicle stopped before entering an intersection.
  
  
• Alcohol and Driver Performance - Using BACSIM software students measure their reaction time, and then see the effect of alcohol on reaction time. Additional activities related to alcohol impairment include:
  

  	Determining the Reaction Zone in Front of a Car
  	Finding Stopping Distance for an Impaired Driver
  	Calculating Impairment Level from Number of Drinks
