Last week, we started a new unit in math, Trigonometry! We learned how to correctly identify the position at which someone shot a gun, by knowing only the length and degree of one leg or angle or a drop of blood. We used pipets to project fake blood onto a large sheet of paper. We then took measurements with calipers of diameter and length of each blood splatter, and from those measurements, using our scientific calculators, we found out the angles of impact. We then connected strings to the measured blood splatters and the stings mostly led to where the "shooter" would have been standing. It was neat to see how we could have accurately figured out a lot of information from one small blood splatter. More fun this week!

Wow. You found a way to make analyzing blood splatters fun. Sounds a lot better than learning it from looking at diagrams.
What a fun way to learn trigonometry. "Dexter" would be thrill about your studying blood splatters. Thanks for the creative way of teaching Trig.
