Data Collection: 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.
Fun Fact: There are free "cricket chirp calculators" online you can explore, which
didn't exist freely online when Pinky was in junior high.
Consider if data was collected consisting of the average number of cricket chirps
at different temperatures in her backyard. in the collection of data list at least 3 important constants?

The three important constants are: The person who will collect the data (Pinky), the environment in which the data will be collected (Pinky's backyard) and the element who will provide the data (the crickets).

Explanation:

Constants are very important elements in carrying out controlled experiments. This is because they allow all measurements and data collections to be carried out in constant systems that do not change and that will provide unity and control to the experiment.

In short, the constants are the elements of the experiment that will not be modified while the experiment takes place. These elements are: the person who is conducting the experiment and who will collect the data (Pinky), the environment in which the data will be collected (Pinky's yard) and the element who will provide the data (the crickets).
