  1. The Effect of Color On Red Harvester Ant Movement By: James Draham

  2. Are Red Harvester Ants attracted to or afraid of certain colors? • If I place Red Harvester Ants in the middle of an assay with colors, then they will go to green most of the time. • If I place Red Harvester Ants in the middle of an assay with colors, then they will not be attracted to a certain color (Null) Problem Statement and Hypothesis

  3. Assay • Eyesight of ants Concepts

  4. Title: The effect of color on harvester ant movement • Hypothesis: If the ants are placed in the assay with colors, then they will be mainly attracted to green. • IV: Start the ant facing certain colors- Green, Red, White, or Black Design Diagram

  5. DV: Harvester Ant Movment • Constants: • Assay used • Lighting • Time allowed for each ant • Type of Ant tested • Weather (Wind, etc.) * *Hopefully conducted inside for no weather issues Design Diagram (cont.)

  6. Safety Precautions • Wear a leather glove • Use tweezers to handle ants • Be positive that lids are sealed on containers
