Experimental Design
Constants are what in an experiment?
Variables that stay the same in an experiment.
Respiratory Rate is also known as your... What is being measured?
Breathing Rate - amount of breaths you take in one minute
Johnny’s heart beats 20 times in 15 seconds. What is his pulse?
80 BPM
What tool is used to measure temperature?
Thermometer
Pulse is measured in...
Beat per Minute
The independent variable is what is being..
Changed in an experiment
Your pulse is measuring what?
The amount of times your heart beats in one minute?
You are studying the impact of a new medication on the blood pressure of patients with high blood pressure. To test whether the medication is effective, you divide your patients into two groups. One group takes the medication, while the other group takes a sugar pill. They take the same amount of medicine for the same amount of time. Then, the blood pressure is measured after taking the medicine.
What is the independent variable?
Blood Pressure Medication
When exercising what will happen to your Respiratory Rate?
Breathing rate will increase.
Respiratory Rate is measured in...
Breathes per minute
The dependent variable is what is being...
Measured in an experiment
Temperature measures what?
Your internal body temperature.
You are studying the impact of a new medication on the blood pressure of patients with high blood pressure. To test whether the medication is effective, you divide your patients into two groups. One group takes the medication, while the other group takes a sugar pill. They take the same amount of medicine for the same amount of time. Then, the blood pressure is measured after taking the medicine.
What is the dependent variable?
Blood Pressure
What is are two things that can cause your blood pressure to be out of normal range?
Stress, Salty Foods, Genetics
Temperature is measured in
Fahrenheit or Celsius
How many independent variables can you have in an experiment?
ONE!!!
Blood Pressure measures what?
The amount of pressure applied to the arteries as blood pushes through.
You are studying the impact of a new medication on the blood pressure of patients with high blood pressure. To test whether the medication is effective, you divide your patients into two groups. One group takes the medication, while the other group takes a sugar pill. They take the same amount of medicine for the same amount of time. Then, the blood pressure is measured after taking the medicine.
Which group is the control group?
The group that takes the sugar pill
When we measure pulse we often measure the amount of beats we feel in 15 seconds, we then multiple that number by what?
4 because 15 x 4 = 60 seconds = 1 minute
MmHg .. Millimeters of Mercury
What is the difference between the control group and the experimental group?
Control Group: The "Normal" Group used as a baseline measurement.
Experimental Group: Receives the Independent Variable/Change.
What are the four vital signs we learned about in this class?
Pulse, Temperature, Respiratory Rate, and Blood Pressure
You are studying the impact of a new medication on the blood pressure of patients with high blood pressure. To test whether the medication is effective, you divide your patients into two groups. One group takes the medication, while the other group takes a sugar pill. They take the same amount of medicine for the same amount of time. Then, the blood pressure is measured after taking the medicine.
Which group is the experimental group?
The group receiving the new medication.
Why are vital signs important?
They are "vital" to our body working properly. Each of the vital signs are indicators that our bodies are working properly.
Why do we measure vital signs?
They are indicators that help to tell us if we are sick.
