a. The Independent variable is Temperature. Option B is correct
b. The dependent variable is Cricket chirping frequency. Option A is correct.
In Pinky's experiment, she's investigating the relationship between temperature and cricket chirping frequency. Therefore:
Independent variable: The variable Pinky manipulates or controls is the independent variable. In this case, it's the temperature. She's changing the temperature to see how it affects the chirping frequency.
Dependent variable: The variable that responds or changes as a result of the independent variable is the dependent variable. This is the cricket chirping frequency. She's measuring the chirping frequency at different temperatures.
complete question:
In a science fair project with independent and dependent varaible.
Pinky's science fair project in junior high focused on an observation that the crickets outside her window chirped less frequently when the temperature was colder. She collected the following data: The average number of cricket chirps at different temperatures in her backyard. a. What is the independent variable? A) Cricket chirping frequency B) Temperature C) Junior high science fair project D) Observation b. What is the dependent variable? A) Cricket chirping frequency B) Temperature C) Junior high science fair project D) Observation
