Surface Tension of a Blood Drop (Screencast)
By Daniel Feucht
This screencast shows how blood droplets are held together by a strong cohesive molecular force that produces surface tension in each drop and on the external force. Surface tension pulls the surface molecules of a liquid toward its interior, decreasing the surface area and causing the liquid to resist penetration.
Summary of Bloodstain Evidence Documentation (Screencast)
This activity will summarize the bloodstain evidence documentation process.
Stain Measurement & Calculating Angles of Impact (Screencast)
In this learning object the student will learn how to measure a stain and calculate angles of impact. Determining the angle of impact for bloodstains takes advantage of the trigonometric functions (Sine function).
A mathematical relationship exists between the width and length of an elliptical bloodstain which allows for the calculation of the angle of the impact for the original spherical drop of blood.
Given well formed stains we can accurately measure the width and length by simply dividing the stain along it’s major and minor axis. The opposite halves would be generally equal to each other which aids in establishing the impact angle.
Spatter Drop Dynamics on Impact (Screencast)
In this screencast, the student will learn that regardless of the surface onto which a blood droplet is falling, the angle or velocity at which it does so, or the volume of the droplet, there are four distinct phases involved in the reaction of a moving droplet with impact against a surface.
Sequencing Impacts Using Radial and Concentric Fractures (Screencast)
By Ronald Groffy
