Therefore, in this activity, you will angle the impact card to represent different angles of impact. Reviews; Welcome. After calculating angles of impact and horizontal direction, forensic scientists start drawing lines, both: Eventually, those lines more or less converge in a particular area, called area of convergence appropriately. SLX 350. stream Don't worry about it, and ignore it in your measurements: this won't be the last approximation leading to the formula for the angle of impact. Use a ruler and a sharp pencil to extend the arrows from each of the bloodstains to find the Area of Convergence. % Under warranty until March 2021! It would be helpful for them to learn about blood spatter first, and to see examples, before doing this activity. Web1.Hello! These worksheets include 10 types of questions about angles. endobj Use the scale to convert to the correct distance. Its value dramatically affects the final shape of blood spatters: look at the figure below! Balthazard [4] demonstrated that the ratio of the minor over the major axis of this ellipse is related to the angle at which the stain impacted the surface. Blood spatter worksheets 3 0 obj Sea Ray Sundancer is a luxury sports boat that has spacious sun pads if you want to soak in the rays with family and friends and it also has comfortable and cozy cabins if you want to take a break from the sunny weather.
