If the Mississippi river is nearly 4,000 km long and an M&M is 1cm long how many M&M’s would it take to measure the
Mississippi river?
$200
Make an observation or ask a question
What is the first step in the scientific method?
$400
True
True or False: The scientific method is a cycle rather than
a list of steps.
$600
What is a hypothesis?
A testable explanation or predication
$800
Quantitative and qualitative
Two types of data you can gather.
$1000
Your research has been reviewed and accepted by other scientists.
What does it mean to be “peer reviewed”?
$200
Manipulated variable
The independent variable can also be called what?
$400
Responding variable
The dependent variable can also be called what?
$600
Provide baseline for data, comparison
What is the purpose of the control group?
$800
The group being exposed to the experiment
What is the experimental group in an experiment?
$1000
Things that remain the same in the lab
What are controlled variables? (constants)
$200
To describe what the graph is representing.
What is the purpose of the title for a graph?
$400
X axis
What axis does the manipulated variable go on?
$600
Y axis
What axis does the dependent variable go on?
$800
What type of graph best represents the data?
$1000
A visual representation of the data, shows trends in the data
What is the purpose of a graph?
$200
Resting heart rate
In the Heart rate lab what was the control group?
$400
What was the manipulated variable in the heart rate lab.
activity
$600
Time, activity, trials, location, how you check your heart rate, etc.
Give 3 controlled variables from the heart rate lab
$800
Heart rate after activity
What was the dependent variable in the heart rate lab?
$1000
What would be an example of a “good” testable question for
the heart rate lab?
“what are the effects of standing, jogging and holding your breath on your heart rate?”
$200
Daphnia Heart Rate Before being exposed to substances
In the Daphnia Lab what was the control group?
$400
The substance being exposed to the daphnia
In the daphnia lab, what was the independent variable?
$600
Heart rate after exposure
In the daphnia lab what was the responding variable?
$800
Any data with a number
Give an example of quantitative data you could
have gathered from the daphnia lab.
$1000
Any observation that involves the senses (no numbers)
Give an example of qualitative data you could
have gathered from the daphnia lab.
