Lab: Can Crickets tell Temperature? Name ________________ Date ________
Some say that if you listen to the sound of a cricket chirping, you
can determine the temperature. Is this true or is this just an
urban legend? Do any other factors affect how fast a cricket will
chirp, such as humidity, wind, atmospheric pressure, or nearby
crickets?
1. This is a virtual lab involving going to the following link:
http://www.gc.maricopa.edu/biology/glacier/scientific_method/index.swf
Ignore the part about submitting your name and Id. Just click on continue. When you get
to the Scientific Method page click on “cricket” . Click through the information, following
the instructions as you go.
2. State the question you are asking. ___________________________________
__________________________________________________________________
3. State the two hypotheses you have about it.
Hypothesis #1: _______________________________________________________
__________________________________________________________________
Hypothesis #2: _______________________________________________________
__________________________________________________________________
4.
For your first hypothesis what is your independent variable? _________________
5. What would the constants be for this experiment? _________________________
6. For your second hypothesis what is your independent variable? _______________
7. What would the constants be for this experiment? _________________________
6.
What is your dependent variable for both? _____________________________
7.
Continue to complete the instructions and when you get to collecting data fill in the
data tables below with your data. After the title for each table, in the first row, identify
the independent and dependent variables where it says I.V. and D.V. Also don’t forget to
write correct units.
Table #1
The Effect of ________________On Cricket Chirp Rate
I.V.
D.V.
Table #2
The Effect of __________________ On Cricket Chirp Rate
I.V.
D.V.
8.
Analysis: Do this part of the lab individually, by yourself (not with your lab group).
Use a sentence to restate your hypothesis and whether the data supports it or not.

9. At this point are you able to answer the experimental question or not? Is there a
relationship between the chirp rate and factors you experimented with. Is more
experimentation necessary? Explain with a few sentences.
