2. Cause of Death
3. Who was there and interacted with her that day
4. Who wrote the note
5. What is the red substance
What search method is the most appropriate for the Anna Garcia scene? Why? -
Answer-Zone; it was in a house/building
What where the 9 pieces of evidence? - Answer-1. Body
2. Red substance
3. Red drips on corner of table
4. Flys
5. Fly eggs
6. Phone
7. Clear liquid
8. Hair on her back
9. Note to meet at the lab
What was the date they found the body? - Answer-8/1 August 1st
What was the time they found the body? - Answer-10:10
Where did they find the body? - Answer-The science lab J. Ever life Science
What was the temperature of the room? - Answer-73°
What are three traits a biomedical scientist needs to solve the case? Why? - Answer-
1. Critical Thinker-think through evidence and trends in data
2. Attentive-can notice small details
3. Assertive-can ask questions and talk to people
Explain why taking precise measurements is important when investigating a case
and reference an item. - Answer-It was important to measure how far away she was
from things to determine if she was using them when she died. For example her
phone.
Why is note taking important? - Answer-You don't have to go back to the scene to
find answers.
Why is sketching important? - Answer-You can make sure the scene is to scale.
Why is photography important? - Answer-You can see what things looked exactly
like.
, Why is videographer important? - Answer-You can get a clearer idea than what a
photo gives on what the scene looks like and notice new things easier.
Give three examples of an action or activity that can affect your heart rate and how. -
Answer-1. Sleeping: decrease in heart rate and respiratory rate
2. Taking a test: increase in heart rate and respiratory rate
3. Physical activity: increase in heart rate and respiratory rate
How did it feel to be interviewed while wearing the sensors? How could this affect
data being collected? - Answer-I felt like I had to control my breathing.
It wouldn't be as natural and accurate.
What happens to your heart rate when you lie? - Answer-Increase
What happens to your respiratory rate when you lie? - Answer-Increase or decrease
Could you analyze experimental data to determine a lie without baseline data? -
Answer-No, you have nothing to compare it to.
Should a polygraph test be allowed as an interrogation method? - Answer-Yes, many
people don't know it's not very accurate so it would compel them to tell the truth.
What question were we researching in the polygraph lab? - Answer-Can the device
detect lying?
How would you summarize the polygraph experiment - Answer-We used physical
sensors to tell if they lie by looking at the data.
What is the independent variable of the polygraph experiment? - Answer-Questions
asked
What is the dependent variable of the polygraph experiment? - Answer-Heart and
respiratory rate.
How do you analyze the data collected? - Answer-We used graphical analysis to
graph changes.
How might you communicate findings? - Answer-Email, lab report, website
What would be a possible source of error in the experiment? - Answer-Lack of
knowledge on how to use/put on the device.
What are three questions you have after evaluating the physiological data taken from
the persons of interest? - Answer-1. Does the data accurately show who lied
2. What did the lies try to cover up
3. why would more than one person lie
How are respiratory rate and heart rate connected? - Answer-If one increases the
other often increase too. The same goes for decreasing.
