Conclusion

Blood Spatter Analysis

Hypothesis

At what height was Anna's blood spattered from?

1. Put apron, gloves, and goggles on. Gather all materials needed.2. Place paper on a flat surface.3, Put yard stick standing up on top of the paper.4. Get your first measurement and drop a drop of blood from pipette. Drop the blood seceral times to improve accuracy.5. Repeat steps 2-4, and measure diamter of the blood spatters6. Record your data.7. Conclusion

HEIGHT (CM) DIAMETER OF B.S (MM)3 cm 1.295 cm .728 cm .8010 cm .6112 cm .58
