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

In this engineering design activity, learners will design, test, and build a “haunting machine” to solve a Sherlockian mystery.

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 math-based activity, learners will experiment to find how height and angle affect spatter and then use this knowledge to solve a crime.
