Crime Scene Science
20 projects and experiments about clues, crimes, criminals, and other mysterious things
Record Your Fingerprints
Materials: Ink Pad, pencil with soft lead, fingerprint record sheet, pen, tape, magnifier
Place students into pairs. Have one student take the fingerprints of the other and then switch roles. Remind students to take each fingerprint carefully so that it does not smudge. Have students examine their own fingerprints and classify them under the four basic patterns (arch, loop, whorl, combination).
- Give each student a handout with the four basic fingerprint patterns
- Have students examine their fingerprints with a magnifying glass
- Chart your Results
Create a Crime Science
Materials: Everyday objects, post-it notes, soft lead pencil, tape, Group chart of fingerprints
The crime scene may be made ahead of time using books, a bottle, cup or mug, anything that a post it note could stick to.
Have each student rub their index finger with a soft lead pencil. Use a piece of tape to capture the fingerprint and place it on a post it note. (the students should put their initials on the back of the post it note)The teacher should collect all of the post it notes and select one to place in the fake crime scene.
Using the group chart of fingerprints, see if the suspect can be found.
Write a Mystery
Read an example from either 65 Short Mysteries You Solve with Science by Eric and Natalie Yoder or Case Closed by Jurg Obrist. Talk about other mystery solvers like Nancy Drew and Sherlock Holmes. Have students write their own short mystery about a crime and how it was solved.
