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. She decides to conduct an experiment to prove her theory. As the temperature rises, it becomes easier to reach a certain activation energy, thereby allowing chemical reactions, such as the ones that allow a cricket to chirp, to occur more rapidly. Hypothesis : Cricket will chirp more if temperature is warmer. Set up habitat. Manipulated variable _____ Responding variable _____ Hypothesis If the crickets are out in a warmer climate, then they will chirp more because people usually hear crickets in the summer when it is hot You only need to construct graphs for the variable(s) that affect cricket chirp rate. You only need to construct graphs for the variable(s) that affect cricket chirp rate. The factor that may change in response to the manipulated variable is called the responding variable (also called the dependent variable). Identify the variables. This enzyme is found in cells and helps break down hydrogen peroxide. A hypothesis must be testable "Perhaps crickets chirp more when the temperature is higher."
