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.

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

This activity is about collecting and analyzing DNA as part of a criminal investigation.

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

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 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 fascinating and fun experiment, learners use chemistry to identify a mystery powder and to solve a "crime," a process similar to that used by real forensic scientists.

In this physics crime lab or demonstration, learners pretend they are criminologists and must find the "muzzle velocity" (speed of the bullet as it leaves the gun) of a gun used to commit a crime.

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.
