We'll have a chance to evaluate the fingerprints and footprints left at our crime soon, in a couple of days. Until then, let's get philosophical for a moment.
When a people are arrested, the police take their fingerprints and a mugshot to document their arrest record. This information is kept for future reference.
Today, we are going to be fingerprinted and have our mug shots taken, but don't take that the wrong way. You are not being arrested, and the information will not be kept for future reference. It is our desire for this to be the last time this happens to you - that you will never be arrested for any reason, that you keep your life positive, and that your life is fruitful.
Once you have your prints, check out this card: Fingerprint Basics. Evaluate your own prints based on your observations and the information on the card. The expected averages are 60% for loops, 35% for whorls, and 5% for arches. How does our class stack up?
After this, let's make tracks. Your team will work together using Hot Wheels or Matchbox cars to identify which cars belong to a set of tracks.
As you press your fingers and the tires onto the paper, you make an impression of the unique lines on your fingers and the unique treads of the car tires. In a crime scene, these unique whorls, loops, arches, and patterns can identify a victim, a suspect, or a vehicle. They are the impression left behind after a person has left the scene.
Think about that for a moment. What you do today, in the classroom, on the playground, leaves an impression on the people around you. This impression may be a positive one or a negative one. What say you? Which direction will your life lead you? Which direction will you seek?
