This manual features 22 challenging, standards-based, inquiry lab activities for AP, IB, and honors programs.
Students use a choice chamber to test the response of fruit flies to different stimuli and determine if there is a significant change in their behavior.
Students test the response of fruit flies to different stimuli and determine if there is a significant change in their behavior. They do this by constructing a choice chamber from drinking straws and cotton swabs and exposing the flies in the chamber to two environments, one on each end of the straw. Students then conduct a chi-square test to determine if the flies display taxis and are indeed favoring one environment over another.
Wingless fruit flies are ideal for use inside the drinking straws. However, other small organisms, such as crickets or pill bugs, can be used. A choice chamber can be constructed from clear PVC or acrylic pipe 0.5–2 inches in diameter, plastic drinking bottles, or Petri dishes, to use with other organisms.
The Associated Bundle:
Contains an EcoChamber, a Metabolism Chamber and all the probeware needed to perform the activities in the Advanced Biology through Inquiry lab manual.
