Fingerprints

Fingerprints

Fingerprint Evidence We leave fingerprints on everything we touch hundreds of times a day. We leave them on drinking glasses, silverware, toys, door knobs, water faucets, books and more. Even though we leave them everywhere, we don’t notice them at all. At a crime scene though, these left behind prints can be very important. Even one fingerprint can solve a case.

The skin on the palms of our hands and on our fingertips are covered with a pattern of ridges. You don’t even need a microscope to see them. These ridges help us grip things. Every single person has a different pattern of ridges. Even the hands and fingers of identical twins are different. The ridges stay the same throughout a person’s life too. These facts are what make fingerprints so useful for crime scene investigators. Fingerprints don’t lie.

Now, learn how to take a fingerprint from an object – this is called picking up latent fingerprints. These are the fingerfetchhat_regprints that have been left behind. One way detectives find fingerprints is by dusting the crime scene for them. Fingerprints are coated with powder, then lifted and taken to a lab for identification.

Here are three website that can help you learn all about dusting for fingerprints.

Now try your skills at Fetch’s crime scene at Canine Sniffer Intelligence: Hat Snatcher. Fetch’s hat has been stolen. Look over the crime scene and collect evidence. You have the skills to figure out which suspect is the true thief. Remember what you have learned about fingerprints.

Memory Skills

Memory Skills

Now that you have practiced observing and listening it’s time to master remembering all the things you have seen and heard. Noticing details doesn’t help much in an investigation if you can’t remember the details later! Let’s see how you do with these simple memory games:

Here are two more memory games that are just a bit harder:

  • Exploratorium: Common Cents This is a hard one! You will be asked to remember something that seems pretty easy – what a penny looks like. You’ll have to dig the details up from your memory bank though. Only one of the pennies is correct. Which one is it? Usually, people remember only enough about an object to recognize it, most people don’t store small details in their memory…if you did well on this test, you have an uncommonly good memory! A great skill for an Ace Detective! It took me about 10 tries to pick the correct penny. I wasn’t very good at that one!

  • Battle of the Badges In this one, look at three different id badges. You will have 30 seconds to memorize all the details you can about each badge. Then you will be shown a series of badges and you will need to decide if each badge is real or a fake.  It really is hard to keep track of several different details like: job title, name & badge color…all at once.

Observation Skills

Observation Skills

Good detectives notice and remember details. You need to be able to concentrate on details with your eyes and store what you see in your memory. Practice can help you get better at this. First, see if you can use your eyes to find hidden harrietthespy_regpictures in the I Spy Game. Then, take it a notch tougher. Take the Harriet the Spy Spy test. Watch this  carefully and then answer the questions that follow. I tried it – it’s tricky!

Next, try these exercises in observation. Spot the differences between two photos and watch a video to see what kind of witness you would make: how many differences you can spot.ciacompare_reg

Listening Skills

Listening Skills

Listening skills are crucial when interviewing both witnesses and suspects. A detective needs to remember exactly what a person said. It also might be important to listen at the crime scene. Is there a lot of traffic at the crime scene? Can you hear barking dogs? Making note of the sounds at a crime scene might help you understand what a witness heard during the crime.

First, try these simple concentration games. The first one is like the classic concentration game. Instead of sounddetectives_regtrying to uncover two PICTURES that match, try to uncover two SOUNDS that match. Don’t be fooled by looking at the pictures. Only listen to the sounds. In the second game, play dominoes by matching SOUNDS, not counting the dots. Finally, take a listenting test with the Time Warp Trio. They need to be Sound Detectives to return stray sounds to their right time period.
