What Can You Figure Out About the Weather by Counting the Cricket Chirps?
Scientific discipline project
Chirping Crickets
Grade Level: 6th -8th; Blazon: Biology
Crickets chirp past rubbing their forewings together in order to attract mates. In this scientific discipline project, y'all will analyze the relationship between temperature and the rate of cricket chirping.
- How many times does a cricket chirp each minute?
- How is the rate of a cricket chirping related to the outside temperature?
If you've gone exterior on a warm summer evening, you've probably heard the crickets chirping abroad. But why does this but seem to happen on warm nights? In this science experiment, yous can explore the connection betwixt outdoor temperature and the chirping of crickets.
- Cricket
- Stopwatch or clock with 2d hand
- Outdoor thermometer
- Locate a cricket. Crickets are easiest to find on warm, dry nights in the summertime.
- Set the stopwatch for 15 seconds.
- Count the number of chirps the cricket that you chose makes in fifteen seconds.
- Repeat this process 4 more than times, inserting your results into a table, such every bit the one below.
- Average your results by calculation upwardly the number of chirps and dividing past five. Insert this number into the tabular array as well.
- Look at the outdoor thermometer and record the temperature in the table every bit well.
- Echo this over the course of a week or 2, listening to a cricket each night that you lot can find 1.
- Clarify your data. Is there any connexion between the average number of chirps that the cricket fabricated and the outside temperature? You lot can make a line graph to better understand your results.
Terms/Concepts: How and why exercise crickets chirp?; When do crickets mate?
