Lab Questions:
How did multiple drops at each height affect your results? What is the purpose of multiple trials in an experiment?
What did you discover about the influence of height on blood diameter in a blood spatter? Could you now accurately infer the height at which a blood drop originated based on the diameter of a blood spatter? Why or why not?
Dropping three drops of 'blood' at each height we tested affects our results because by having multiple drops for each height, we could find the average diameter of the blood drops at each height. Finding the average enabled us to make sure that the answers we got were okay and made sure none of our drops were abnormal. The purpose of multiple trials in the experiment was to make sure that our results made sense and didn't give us wrong answers.
I think that the influence height has on the diameter of a blood spatter is that the size of the blood spatter gets bigger the higher (or farther) away you are from where the blood falls. At this point I think I could infer the height at which a blood drop originated at but not super accurately. I think that it would take a bit of time, and a few more tests, to figure out where the blood originated at accurately. Probably with a little bit of time (and math) I could figure out where blood drops originated at but a few more trials with blood drops would be helpful.
For now I'll leave the professional work up to the professionals...
