Blood Spatter Analysis

Your students must determine how the blood spatter found at the cabin
scene was formed. To do this, students first learn about the techniques
for blood spatter pattern analysis. Then, students will conduct an
experiment designed to determine the relationship between the height and
angle of impact of a blood drop and the size of shape of the spatter.

Students drop synthetic blood onto paper at different heights and
angles in and then measure the size and shape of those drops.
Afterwards, they will use MS Excel or another spreadsheet program to
analyze their data and build a mathematical model.

After students have created their model, they will apply it to the
blood spatter patterns found in the cabin. By running strings that
attach to the blood in the crime scene model’s walls at angles predicted
by their model, students will be able to determine the point of impact
that caused the spatter.

As in all Lyle and Louise modules, this kit is geared to high school
and undergraduate courses, and is matched to National Science Education
Standards.
