Does the frequency at which crickets chirp change with environmental temperature?
INCLUDE ALL OF THE FOLLOWING WITH YOUR EXPERIMENTAL DESIGN:
[remember it must be a controlled experiment]
1. A hypothesis: Crickets chirp less in the winter from being cold but more in the summer from being warm.
2. Explain how to set up the experiment:
brainstorm a list ofall the variables that must be kept constant during the experiment: Keep crickets alive, make sure they have food to survive, puncture small holes in the jar so they can breath, make sure you keep the heater running at all times, keep the crickets nearby so you can hear which ones are chirping the most, do not change the thermostat for it will change the room temperature, keep them in their habitats for the same amount of time, record down how many chirps are coming from each, don't let the crickets in the refrigerator freeze to death, make sure the incubator is at a higher temperature than the room temperature.
include identification of the independent variable: The crickets in their habitats.
the dependent variable: The frequency of chirps from the crickets
identify the control group: The crickets kept at room temperature.
identify the experimental group(s): The group in the freezer and the group in the incubator.
3. Provide enough details for someone else to set up your experiment
Catch 30 crickets and split them into 3 groups of 10. Then put each group in a jar. Put one jar in the refrigerator for a cold temperature. Next put another jar in an incubator or in front of a heater for a warm temperature. Finally put the last jar in a room at room temperature that they are used to.
