Experimental Design
A possible answer to a scientific question.
What is hypothesis?
The three common disease agents that we have learned about in this unit.
What are virus, fungus, and bacteria?
This vital sign is measured in beats per minute. It can be measured using an oximeter or by pressing two fingers against one's wrist.
What is heart rate?
The process of identifying a disease by examining a person's symptoms, behavior, and background.
What is diagnosis?
COVID was caused by this microorganism.
What is a virus?
The variable that is observed or measured in an experiment.
What is a dependent variable?
The microorganism (disease agent) that reproduces quickly in moist, humid environments. Athlete's foot is caused by this disease agent.
What is a fungus?
This vital sign is measured with a thermometer and measured in degrees Fahrenheit.
What is temperature?
The signs of disease or injury. These are important clues in diagnosing a patient.
What are symptoms?
What has been your favorite part of medical detectives so far?
Everyone gets a point!!
The variable that is purposely changed in an experiment.
What is the independent variable?
The microorganism (disease agent) that causes diseases like E. Coli or Strep throat. Not all strains or species of this microorganism are bad, some can be helpful.
What is bacteria?
This vital sign is measured by counting how many times someone's chest rises in one minute.
What is respiratory rate?
(Show picture). The result of this test.
What is negative?
The force of the blood pushing against the artery walls as the heart contracts and relaxes. This vital sign is measured using a monitor that records two numbers (systolic and diastolic).
What is blood pressure?
The dependent variable in the scientific question, "How does the amount of water affect plant height?"
What is plant height?
The disease agent that is too small to be seen in a regular classroom microscope.
What is a virus?
This happens to your respiratory rate when you are biking.
What is increases?
Antibiotics are often used to treat diseases caused by this disease agent.
What is bacteria?
What is control group?
The independent variable in an experiment where students measure their vertical jumping height in different types of shoes to see if the type of shoe has an affect on the height someone jumps.
What are types of shoes?
This happens to your heart rate when you are dehydrated.
What is increases?
