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.
