In this activity, learners examine fingerprints. Learners leave a hidden print on a surface and then make their own print detecting powder from graphite (found in pencils).

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.

The purpose of this lab activity is to demonstrate (through simulation) how DNA fingerprinting (or DNA profiling) might be used to solve a crime.

Learners mix a solution containing luminol and copper with a fake blood solution. A chemical reaction between the luminol solution and fake blood (hydrogen peroxide) show learners a blue glow.

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

In this activity, learners extract DNA from their own cheek cells, then create a rudimentary DNA profile similar to those seen on crime scene dramas.

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

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

This activity (on pages 15-23) combines interactive role-playing and graphing to introduce learners to the health affects of pollen.

In this activity, learners perform a simulated blood test procedure.

In this activity (page 1 of the PDF under SciGirls Activity: Forensics), learners will use a home video camera with a “night vision” mode to test how various inks appear outside the spectrum of visibl

In this forensics activity, learners solve a mystery using “DNA” taken from the scene of the crime.

This activity (on page 2 of the PDF under SciGirls Activity: Forensics) is a full inquiry investigation into how hairs from a crime scene are matched to suspects.

In this two-part activity, learners will extract their own DNA from their cheek cells and learn how DNA is analyzed and used to solve crimes.

In this outdoor, mystery-solving activity, learners work like detectives, gathering evidence to identify the culprits that are attacking plants.

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

This exercise can be used to stimulate the investigative nature of learners as they use forensic plant pathology techniques to prove the learners' innocence in a mock murder investigation.

In this experiment, learners will conduct chemical and physical tests to identify mystery substances.
