Jimmy and jenny have designed an experiment to test how termites react to the chemicals in ink pens. they use one termite in their experiment. jenny draws four circles, using four different brands of black ink. jimmy places the termite on each circle of ink and they watch the termite's behavior as it is placed on each circle, one try per circle. in all four cases, the termite veers off the ink circle. jimmy and jenny conclude that termites are not attracted to ink at all. what suggestion would you give jimmy and jenny concerning their experimental design?
