Ask a Cricket, 'What is The Temperature?'Difficulty. Time Required. Long (2- 4 weeks)Prerequisites. You must be in an area where you can hear crickets chirping. Yes, that is right! In this science fair project, you will investigate how the chirps of these tiny creatures can do more than lull you to sleep—they can tell you the temperature! Zoo. It is an unmistakable sound.

Some people find the sound pleasing and peaceful. Some think that crickets bring good luck, and keep them as pets in beautifully decorated cages. Other people find the sound loud and annoying, especially if a cricket happens to get inside a home to escape the cold.

The Activation Energy of Chemical Reactions. Only a small fraction of the collisions between reactant molecules convert the reactants into the products of the reaction. 89 The European Journal of Mineral Processing and Environmental Protection Vol.1, No. 2,1303-0868, 2001, pp. 89-102 Technical Note Kinetic study of the thermal. General form. The general form of the Eyring–Polanyi equation somewhat resembles the Arrhenius equation: = The viscosity of a fluid is a measure of its resistance to gradual deformation by shear stress or tensile stress. For liquids, it corresponds to the informal concept.
However you feel about crickets, their chirps hold a surprising message— they can be used to predict the outdoor temperature! How is this possible? Crickets, like all other insects, are cold- blooded. They take on the temperature of their surroundings.
Many characteristics of cold- blooded animals, like the rate at which crickets chirp, or the speed at which ants walk, follow a special equation called the Arrhenius equation (which you can investigate further in the Variations section in the Make It Your Own tab). This equation describes the activation energy or threshold energy required to make a chemical reaction occur. For instance, crickets, like other living things, have many chemical reactions going on inside their bodies. As the temperature rises, it becomes easier to reach a certain activation or threshold energy, and chemical reactions, like those that occur during the muscle contractions used to produce chirping, can occur more rapidly.
As the temperature falls, the rates of the chemical reactions inside the crickets' bodies slow down, causing characteristics, such as the chirping, to also slow down. How do crickets make their distinctive chirp? Crickets and other insects cannot talk or sing the way humans do. They make sounds in a process called stridulation, where special body parts on their wings are rubbed together to make a noise. In crickets, generally only adult males make noises, and usually only at night. There is a special structure on the top of their wings, called a scraper. The crickets raise their wings to a 4.
It is somewhat like running your finger along the teeth of a comb. Rzadkowski/Wikimedia Commons).
As far back as the late 1. If you want to hear examples of cricket chirps under hot, warm, cool, and cold conditions for yourself, visit these sound recordings of the snowy tree cricket. There have been many equations published, describing the relationship between the number of chirps per second and the temperature.
These equations all vary slightly, depending upon the species of cricket, but the snowy tree cricket is frequently cited as the most accurate at predicting temperature. One of the oldest and easiest- to- use cricket thermometer equations is published in the Farmers' Almanac, a famous book updated each year and used to predict the weather. It says that if you want to get the temperature in degrees Fahrenheit, count the number of chirps over a 1. Equation 1. TF = N1. TF is the temperature (in . N1. 4 is the number of chirps in 1. To get the temperature in degrees Celsius, the Farmers' Almanac says to count the number of chirps in 2.
Equation 2: TC is the temperature (in . Outside that range, the crickets find it too cold or too hot to sing! Grab a stopwatch and a.
Only adult male crickets chirp, so if you buy them at a pet store, make sure you purchase several to ensure that you get at least one male. Listening to crickets in an outdoor area is preferable, because sometimes caged crickets do not chirp much, or at all. Helper. Stopwatch.

Using Equation 1 or Equation 2, calculate the outdoor temperature, based on the number of cricket chirps, and record your calculation in your data table. Plot the average number of chirps in 1. Celsius) on the x- axis, and the calculated and measured temperatures on the y- axis. Did the Farmers' Almanac equation accurately predict the measured temperature? If the calculated temperature was different from the measured temperature, how different was it? If you have specific questions about your science fair project or science fair, our team of volunteer scientists can help.
Our Experts won't do the work for you, but they will make suggestions, offer guidance, and help you troubleshoot. Zoologists and wildlife biologists tackle all these questions. They study the behaviors and habitats of wild animals, while also working to maintain healthy populations, both in the wild and in captivity. Biologists are the scientists who study life in all its forms and try to understand fundamental life processes, and how life relates to its environment. They answer basic questions, like how do fireflies create light?
Why do grunion fish lay their eggs based on the moon and tides? What genes control deafness?
Why don't cancer cells die? How do plants respond to ultraviolet light?
Beyond basic research, biologists might also apply their research and create new biotechnology. There are endless discoveries waiting to be found in the field of biology! It's not as smart as you are, and it may occasionally give humorous, ridiculous, or even annoying results!
