In this crime science activity (on page 2 of the PDF), learners will explore the uniqueness of fingerprints. The will learn components of fingerprints as well as why fingerprints are left behind.

In this experiment, learners separate different types of molecules in marker inks (using a technique called "thin layer chromatography").

In this activity, explore chromatography and the various colors that make up the ink in markers. Use this activity to investigate cohesion and adhesion.

In this activity (on page 2), pairs of learners create an imaginary crime scene. One person leaves the room while the other person moves a few things around.

In this activity, learners simulate the process of DNA fingerprinting by using electricity to separate colored dyes.

With a coffee filter, a black marker, and a cup of water, discover the secret colors hidden in black ink.

In this activity, learners explore acid and bases as they create their own invisible ink out of baking soda and grape juice.

In this health activity (page 5 of the PDF), learners will explore a unique connection betweeen the bones of the body.

In this activity, learners use mirrors to write secret messages to a friend. Use this activity to explore letters, optics, and/or symmetry.

In this math lesson, learners explore variables and their uses.

In this activity, learners examine their fingerprints and learn that they can be categorized by shape, but each fingerprint is unique.

In this Cyberchase activity, learners make decoders to send and receive secret messages. Learners make the device out of two 8-ounce cups and two code strips.

In this activity, learners become detectives and use chemistry to investigate fingerprints.

In this activity, learners write a secret message in "invisible ink" and then use chemistry to view the writing.

In this activity (on page 2) about fingerprint analysis, learners use graphite from a pencil and scotch tape to capture their fingerprints.

In this activity, learners explore genes and traits. Learners investigate their fingerprints and learn how to categorize them.

Learners roll their fingerpads in ink pads, and then press their fingerprints onto balloons. Learners inflate the balloons to produce enlarged versions of their fingerprints.

In this forensics activity, students will explore the methods that investigators use to confirm the authenticity of handwriting.

In this demonstration (9th on the page), learners explore eyewitness memory and how memories differ amongst individuals. While the rest of the group is minding their own business (i.e.

In this optics activity, learners build a spy tool to secretly view things over walls or around corners.
