Unit 7: Blood & DNA: The Silent Witnesses

LP 7.1 Students will be able to (I can) analyze blood spatter through the relationship between the height/velocity of a drop and the resulting satellite or spike patterns, as well as the geometric principles used to calculate the angle of impact.

LP 7.2 Students will be able to (I can) construct a genetic profile based on the structure of DNA and bloodstain

STUDENTS WILL:
Students will be able to analyze blood evidence at a crime scene by using serological testing to confirm its presence, applying the physics of fluid dynamics to interpret bloodstain spatter patterns for scene reconstruction, and evaluating DNA profiling techniques to conclusively identify a suspect.
