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 chemistry activity, learners use thin layer chromatography to determine the molecular composition of different markers.

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

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

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

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

In this physical sciences activity, learners use science to solve a "crime." Learners collect trace evidence (glitter) and explore its characteristics, such as color, size, shape, and light reflection

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

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

This lesson is designed to serve as an introduction to the immune system. It can stand alone or it can lead into further studies of the immune system.

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.

Learners use scientific processes to solve a crime. As they get clues, learners must create a hypothesis then adjust that hypothesis as more information is revealed.

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

In this physical sciences activity, learners explore how forensic investigators collect prints from a crime scene. Learners make hand impressions in damp sand and analyze the patterns they observe.

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