Ziplock bags

Colored Markers

Stop watch

Counter

Thermometer

Sling psychrometer & conversion chart for humidity

Map of Local Area

 

Methodology:

  1. Instructor will lead students to a pre-selected area with ant colonies of a local species.
  2. Students will then choose a point for measurement along ant trail going into the colony opening.
  3. Students will then count and collect data for 15 minutes.
  4. Students will determine frequency of worker ants for 1 minute out of every 5 as they cross the predetermined point into colony.
  5. Students will take environmental data including air temperature, soil temperature, canopy cover, and % humidity.
  6. Students will make and collect general observations of colony especially what role the ants play in the environment.
  7. Students will discus observations and generate questions based on what was seen in the field.
  8. Students will develop a testable hypothesis.
  9. Students will develop an experimental methodology in order to test their hypothesis.
  10. Students will carry out the experiment and collect and record data.
  11. Students will present and discuss their findings with the class.
