II.B.1 Part Two-Compiling and Analyzing the Data

Each student will need:

Instructions for the teacher:
  1. After the data have been collected, return to the classroom to analyze it. Distribute a copy of the Class Data Worksheet to each student.
  2. Answer the questions on the Class Data Worksheet as a class. When this information has been collected, try answering the questions below:
  • Did you find one or two different species of wolf spiders?
  • What kind of habitat does the scrub burrowing wolf spider prefer?
  • Do the spiders live near each other? If so, why do you think they do?
  • Did you find both small and large burrows within the flagged area? (Adult spider burrows are approximately 10mm wide. Young spider burrows are approximately 5mm wide.)

After participating in this activity, your students should:

  • Understand the concept of ecological niche.
  • Understand the concept of a microhabitat and give examples.
  • Give examples of spider adaptations.
  • Be able to carefully observe and measure.
  • Participate in discussions and learn cooperatively.

Further Questions and Activities for Motivated Students

  1. Observe marked spider burrows over a period of time (several months to a year). Do the number of burrows increase or decrease with time, season or weather conditions?
  2. How do sand-loving scrub burrowing wolf spiders deal with a heavy rainfall? How long does it take for the spider to repair the damage to its burrow?
  3. How does the ratio of small burrows to large burrows change from one day to the next? From one week to another? From one month to another?
