meter
The metric unit used to measure length
5
400
gram
The metric unit used to measure weight.
6
600
liter
The metric unit used to measure volume
7
800
1 ml
How many milliliters are in 1cm3
8

400,000,000 MMs
If the Mississippi river is nearly 4,000 km long
and an MM is 1cm long how many MMs would it
take to measure the Mississippi river?
9
200
Make an observation or ask a question
What is the first step in the scientific method?
10
400
True
True or False The scientific method is a cycle
rather than a list of steps.
11
600
What is a hypothesis?
A testable explanation or predication
12
800
Quantitative and qualitative
Two types of data you can gather.
13
1000
Your research has been reviewed and accepted by
other scientists.
What does it mean to be peer reviewed?
14
200
Manipulated variable
The independent variable can also be called what?
15
400
Responding variable
The dependent variable can also be called what?
16
600
Provide baseline for data, comparison
What is the purpose of the control group?
17
800
The group being exposed to the experiment
What is the experimental group in an experiment?
18
1000
Things that remain the same in the lab
What are controlled variables? (constants)
19
200
To describe what the graph is representing.
What is the purpose of the title for a graph?
20
400
X axis
What axis does the manipulated variable go on?
21
600
Y axis
What axis does the dependent variable go on?
22
800
What type of graph best represents the data?
23
1000
A visual representation of the data, shows trends
in the data
What is the purpose of a graph?
24
200
Resting heart rate
In the Heart rate lab what was the control group?
25
400
activity
What was the manipulated variable in the heart
rate lab.
26
600
Time, activity, trials, location, how you check
your heart rate, etc.
Give 3 controlled variables from the heart rate
lab
27
800
Heart rate after activity
What was the dependent variable in the heart rate
lab?
28
1000
what are the effects of standing, jogging and
holding your breath on your heart rate?
What would be an example of a good testable
question for the heart rate lab?
29
200
Daphnia Heart Rate Before being exposed to
substances
In the Daphnia Lab what was the control group?
30
400
The substance being exposed to the daphnia
In the daphnia lab, what was the independent
variable?
31
600
Heart rate after exposure
In the daphnia lab what was the responding
variable?
32
800
Any data with a number
Give an example of quantitative data you could
have gathered from the daphnia lab.
33
1000
Any observation that involves the senses (no
numbers)
Give an example of qualitative data you could
have gathered from the daphnia lab.
