Blood Splatter Lab
Blood Splatter Analysis Lab
Independent Variable & Dependent Variable:
Independent: Blood Spatter
Dependent: Diameter (size of blood splatter)
Problem Statement:
What height did the blood at the crime science fell from
Hypothesis:
Anna Garcia might have tripped which caused her blood stain to reach the maximum height of the stool, which means her blood splatter fell lower than her height.
Materials:
Gloves
Eye Droppers with blood
Journal
Yard Stick
Clear ruler
Blank piece of paper
Graph
Procedures:
1. Put on Gloves
2. When your teacher allows you to grab the simulated blood, shake the bottle lightly, and find a place to work.
3. Start at a height of 20cm on your yard stick, and drop the blood to the white piece of paper
4. Measure the diameter of the blood splatter with your small, clear ruler and measure in inches, then convert inches into Millimeters, once you have it in Millimeters, record it into your graph paper.
5. Next measure at a height of 40cm on your yard stick, and drop the blood to the paper
6. Once again, measure the diameter of the blood splatter with your ruler and measure in inches, then convert inches into Millimeters, once you have it in Millimeters; record it into your graph paper
7. Repeat steps 3-4 (60, 80, 100, 120, 140, and 160) until you reached Anna’s height which was 163cm (162.56cm) and measure the diameter in inches into Millimeters and record it onto your graph.
8. Measure the diameter, then convert cm into Millimeters
9. Once you’re finished, do a hypothesis, on what might have happened to Anna and at what height was she in when she died, find the dependent and independent variable, do a summary, and a conclusion, to explain what you and your partner did and what were your results.
Conclusion:
By collecting evidence in Anna Garcia’s crime scene, she fell at the height of the stool, which is where her blood marked.
Summary:
In the experiment, it concluded that Anna might have tripped,
