WorksheetsMed Bio: Snake Venom Lab Practicum
Total questions: 15
Worksheet time: 8mins
Based on the snake venom lab, what was the original problem driving this lab?
people are have more injuries from bites from the brown recluse
There has been an increasing number of rattlesnake bites in San Diego County.
There has been an increased number of Cobra bites in Imperial County.
Black Widow spiders are biting more people.
Based on the lab, what were you measuring for your dependent variable?
amount of blood drops
amount of venom drops
amount of antivenom drops
time it takes to clot blood
Based on the results of the lab, which venoms had the fastest clotting time?
Helleri
Scutulatus
Pyrrus
Atrox
Based on the results, which venom was the most responsive to the Fab2 antivenom?
Helleri
Scutulatus
Pyrrus
Atrox
How would you know if antivenom was the most effective on the clot?
The clot would have seized up more
The antivenom would have made the blood thinner
The clot would have broken up all the way and the blood would look homogenous
The clot would separate into chunks
What should have happened right after you added your total drops of venom to the blood?
watched and waited for a clot to form
stirred the blood with the pipette
How do most prey die when bit by a snake?
brain damage
bleeding out
infection in bite area
stroke or cardiac arrest
True or False: Some venoms can cause paralysis?
True
False
Which species of snake is found in the Imperial Valley?
Crotolus Atrox
Crotolus Oreganus Helleri
Crotolus michelli pyrrus
Crotolus Oreganus Lutosus
From the lab, what was your independent variable for the first experiment?
blood type
venom amount
different snake venoms
time it takes to clot
From the lab scenario, what did 3 or the 4 snake bite patients die from?
CroFab antivenom
Crotolus oreganus toxins
Crotolus atrox toxins
What did the beaker of Sodium Citrate represent in the lab?
The blood
The clotting factors
The original venom
The antivenom
What could have been an error that would have in-validated your results?
adding more venom than antivenom
not wearing goggles
stirring the blood with the pipette
adding more blood than venom
What would have been the best title for your graph?
The effect of snake venom on blood
The Clotting Time of Snake Venoms and Anticoagulant Time of Antivenom
The time it takes for snake venom to clot blood
What is the best suggestion for another experiment like this?
Everyone retest the same thing
Everyone adds 7 blood drops and 3 venom drops
Get new venoms to test
Half the class test the venoms, half the class test the antivenoms
