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

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 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.

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 (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 of the PDF (Get Cooking With Chemistry), learners conduct chemical tests on certain powders used in cooking.

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.

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

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

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

En esta actividad, los aprendices leen sobre como Mateo y Cientina conducen una investigación forense para descubrir quien llevó unos dulces.

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

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.
