  1. STEM Program - Termites By: Sydney Luffman & Scarlett Edmunds

  2. The Background of Termites • Diet: Termites usually feed on cellulose, a substance found in wood, cardboard, and paper. • The most common termite found in our area is the Subterranean termite. • Some termites build a home out of dirt and saliva. They engineer this home to have its own special form of air conditioning.

  3. What TJ Showed Us • TJ, one of our instructors, had drawn a black circle on a sheet of paper, and the termite followed the line. • Our experiment was to discover why the termite did this.

  4. Our hypotheses • Termites are attracted to the color black. • Termites are attracted to something in the ink. • Termites follow the indentation. • Termites always walk in a cirlce.

  5. Our Experiment with Predictions Key: N = no Y = yes

  6. Photos of the Experiment 1. 2. 3. Bic Black Pen Bic Red Pen Bic Black Triangle Pencil Papermate Blue Pen 4. 5.

  7. Our discoveries • Termites did walk in a circle drawn with the Bic red ink, and in a triangle drawn with the Bic black ink. • They did not follow the circle with pencil, Black felt tip, Papermate blue ink, or stylus. • The termites also wandered aimlessly when there was nothing.

  8. Our Conclusion • We concluded the termites are attracted to a chemical in Bic ink. • TJ then gave us the “big reveal”. The chemical in the ink is similar to the termites’ own pheromone trail, which they emit to lead them to food.
