In this chemistry demonstration, learners will discover that phenolphthalein is a chemical that displays different colors depending on the acidity or basicity of the environment.

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 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 explore acid and bases as they create their own invisible ink out of baking soda and grape juice.

In this hands-on activity (on page 2 of the PDF), learners experiment with lemon juice and paper to create a message that can only be revealed using chemistry.

Learners write an invisible message using lemon juice on a piece of paper. They then develop the message by soaking the paper in a dilute iodine solution.

In this activity, learners write invisible messages on goldenrod paper, and make the message appear and disappear using acids and bases.

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

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 activity, learners create a necklace of wheat germ DNA. Learners add alcohol to wheat germ so that the DNA clumps together.

Learners use filter paper and water to analyze six different markers. They mark the paper with ink, and dip the paper in water. The water travels up the paper and dissolved ink travels with it.

Learners press their fingertip onto a clean Plexiglas sheet. The fingerprints are then revealed as learners dust over the print with fingerprint powder.

In this activity, learners combine two substances (plaster of Paris and water) to make a cast of an object's imprint in clay.

Learners observe different paper samples under ordinary room light and under a black light to learn some of the chemical differences between different types of paper.
