By the end of this lab you will be able to:
Your task in this lab is to explore the process of scientific inquiry by investigating the reason and timing of cricket chirps using an online tutorial that was developed by Glendale Community College in Glendale, AZ that will allow you to review steps of the Scientific Method and design your own experiment. To begin, open this interactive website on the Scientific Method:
http://webapp.gccaz.edu/academic/biology/scientific_method/
Click on the “Tutorial” button at the bottom of the screen to begin. Following the instructions provided in the introduction, complete the entire tutorial and then answer the questions below. It is highly recommended that if you do not answer the questions in the tutorial correctly, repeat the exercises until you get it correct.
There is a glitch in the tutorial. When you get to the flower logic problem, do not select the box labeled “White White” as your first selection. The solution the tutorial gives you when you select this box is incomplete.
In this activity, you will be given 5 potential experiments to run to test the reason that crickets chirp. Your task is to test all 5 of the experimental conditions to test, collect your data, and draw conclusions based on your experimental results. To be most efficient with your time, answer the questions below as you go.
Perform the experiments, testing every hypothesis made available to you. Collect at least 5 data points for each hypothesis. Record your data in the tables below. Regardless of which hypothesis you believe to be the most likely, you must still collect at least 5 data points for all 5 hypotheses.

Data Analysis
After collecting and analyzing your data, there are a series of questions to answer regarding your results. Complete all the questions. BE VERY CAREFUL WHEN DETERMINING WHAT THE QUESTIONS ARE ASKING!! THERE ARE SOME TRICKY ONES THAT YOU MUST THINK ABOUT CAREFULLY!! Be sure you understand what is being asked, and are absolutely certain the options you choose can actually be determined from the data you have! (You do not need to print the trophy when complete.)
Provide a descriptive paragraph below explaining how you used your data to draw the appropriate conclusions. Address the following questions in your analysis:
