Observing your pillbugs behavior

• How do the pillbugs seem to sense their
  environment?
• Are they all the same species?
• Can you tell differences in males and females?
• How many eyes do they have?
• How many legs?
• Do they exhibit any dominance behaviors?
• How do they respire?
• How do they grow?
• What are some stimuli they seem to respond to?

13
Drawing your pillbug

• 1. Determine the relative proportions
• a. width length
• b. height length
• c. distance between eyes width of body
• d. length of antennae length of body.
• 2. Count the number of body segments.
• 3. Count the number of legs.
• 4. Locate the eyes.
• 5. Label the body parts.
• 6. Note the size of the pillbug.

14
Observing your 10

• Put 5 on each side
• Every minute (or .5 min), count and record how
  many on each side.
• YOU CAN STILL BE DRAWING DURING THIS SECTION.

15
Designing a controlled experiment

• HYPOTHESIS/PREDCTION
• Poor I think pillbugs will move toward the
  wet side of a choice chamber.
• Better If pillbugs prefer a moist environment,
  then when they are randomly placed on both sides
  of a wet/dry choice chamber and allowed to move
  about freely for 10 minutes, most will be found
  on the wet side.

16
Designing a controlled experiment

• Experiment
• In a controlled experiment, you must explicitly
  keep all variables constant except the one you
  are manipulating.

17
Designing a controlled experiment

• Experiment
• YOU HAVE your independent variable given you
  must design and execute a controlled experiment.
  
• You may need supplies, get them from Mrs.. Hobby
