Crickets: Conducting Observations

Purpose

The student will make observations of cricket behavior by checking off behaviors as they are observed. This same checklist can be used to tally the number of times a particular behavior occurred in specified time.

Handling the crickets

The observations can be made of the crickets in their aquarium. Clear plastic sweater boxes with several crickets in each can be observed by a pair or group of students. Cultures containing adults will have a wider range of behaviors than a culture of young nymphs. This activity can also be conducted throughout several days/weeks until most of the behaviors are observed. It is best to isolate the male crickets from the rest of the crickets for a day or more in order to get good observations. The females can be together in their culture.

Procedure

Place five males separately in the observation chamber while keeping them confined by using an upside down baby food jar or vial. Five females may wonder freely in the observation chamber. Set the timer for twenty minutes and lift the test tubes off the males and record what happens. It may take five minutes or so for the crickets to adjust to the observation chamber.
