If an experiment is conducted to see how temperature affects the number of cricket chirps per minute, then a cricket will chirp more frequently in warmer temperatures than in cooler temperatures because crickets are more active in a warmer environment. The chirping of the more familiar field crickets is not as reliably linked to temperaturetheir chirping rate alters depending on other elements such as age and mating success. Measure ambient temperature and sound intensity in decibels. Tymbals are membranes located on the abdomen that are moved by muscles. Which means that they get more active in higher temperature conditions. Camel crickets are one of such crickets. For example: (1) crickets generally do not sing at temperatures below 55 F or above 100 F, (2) some crickets do not chirp in discrete bursts, they utter a more continuous trill, (3) chirp rate is affected by other factors such as the cricket's age, mating success, hunger, and with competition from nearby males. variable any factor, trait, or condition that can exist in differing amounts or types independent variable variable changed or controlled by scientist dependent variable Copyright 2002-2023 Science Buddies. from Science Buddies, This activity brought to you in partnership withScience Buddies.
