Animal Behavior
   2 Part Lab
     Part   A: Response to Environmental Variables
        Activity A1: Initial Observation of Isopod Behavior
        Activity A2: Orientation Behavior of Isopods
        Activity A3: Designing an Experiment to Test
         Isopod Behavior

National Science Education
Standards
   Unifying Concepts and Processes
     Systems,order, and organization
     Evidence, models, and explanation
     Constancy, change, and measurement
   Science as Inquiry
     Abilities necessary
                       to do scientific inquiry
     Understandings about scientific inquiry
   Life Science
     Behavior   of organisms
Objectives
 Observe animal behaviors relating to
  environmental stimuli
 Observe courtship behavior
 Design and conduct animal behavior
  experiments
Isopods
   Terrestrial Isopods
        Sowbugs (Porcellio laevis)                 and pill bugs
        (Armadillidium vulgare)
             Roly-polies, potato bugs, wood lice
        Breathe  with gills, must remain moist
        Similar size, color, and life cycle
        Different Response to threats
             Pill bugs- curl up in tight ball for protection
             Sow bugs- either flee or remain perfectly still, appearing
              to be dead
Procedure- Activity 1A
   Observe the isopods for 10 minutes.
     Observe             in their undisturbed behavior
 Note their behavior.
 Did you note any agonistic behavior (social
  interaction)? If so, explain the behavior.
 Are the movements of the isopods better
  described as taxis or kinesis movements?
       Taxis- an innate behavioral response by an organism to a directional
        stimulus or gradient of stimulus intensity
            EX. Chemotaxis, phototaxis, geotaxis, thermotaxis
       Kinesis- like taxis, a movement or activity of an organism to a stimulus.
        Different from taxis in that the response to the stimulus provided is non-
        directional
Procedure- Activity 2A
 Place clean filter paper into each side of the choice
  chamber.
 Using the dropping pipet, saturate the filter paper
  on one side of the chamber. Pour off any excess
  water; do not let the water run into the other side
  of the chamber or moisten the paper there.
 Using the sorting brush to transfer 5 isopods to
  each side of the chamber. Put on the lids.
 Count and record in Table 1 the number of
  animals on each side of the chamber, every 30
  seconds for 10 minutes. Continue to record even if
  the isopods all move to one side or stop moving.
Procedure: Activity 3A
   Design an experiment to test isopod behavior

      Cool vs. Warm                       Resealable plastic bag filled with   Resealable plastic bag filled with
                                          ice                                  warm water


      Light vs. Dark                      Exposed to light                     Wrapped with aluminum foil



      Light vs. Shade                     Exposed to light                     Covered with several screens



      Low pH vs. High pH                  A few drops of NaOH on filter        A few drops of HCl on filter paper
                                          paper


      Substrate material vs. Absence of   Substrate material present           Substrate material absent
