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).

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.

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

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 activity, learners perform a simulated blood test procedure.

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