Sugar, Sugar

Problem

Are sugar ants more attracted to coke, syrup, or chocolate?

Null Hypothesis

If we take 12 sugar ants and put them in simulation of 3 connected Petri Dishes they will distribute evenly among the coke, syrup, and chocolate; therefore, there should be 4 ants at each substance.

The Manipulated Variable

Sugary substances that are placed in the dishes.

3 Constant Factors

The 3 constant factors used in this experiment are coke, syrup, and chocolate.

Materials

1. Coke

2. Hershey's Kiss

3. Syrup

4. Dropper

5. Petri Dishes

6. Ants

7. Plastic Tubes (Hold the ants)

Procedure

Manipulated variable - Take drops of each substance and place it into each dish. Take observations, and see which substances the ants are attracted to.


Control procedure - Air, and surroundings are not changed. Lighting is the same. No temperature change.

Manipulated and Controlled Data

Manipulated (timed every 30 seconds) Coke, Syrup, Chocolate

(5,5,2) (5,5,2,) (5,5,2) (4,5,3) (4,6,2)


Controlled (timed every 30 seconds) Dish 1, Dish 2, Dish 3

(3,5,5) (2,4,6) (2,4,6) (3,4,5) (3,4,5) (5,3,4)

Observation

12 ants were all put into the center of the three petri dishes. Very quickly, the ants separated between the three. Within the first minute the ants split mainly between the syrup and the coke with 5 and 4. The chocolate had the lowest amount containing two ants. Surprisingly at the end of the three minutes, syrup (although coke had the most concentrated amount of sugar) with held the most ants (6).

Chi-Squared Results

P= .525625

Failed to reject our null hypothesis.

Conclusion

The Null Hypothesis was failed to be rejected. Our assumption that the majority of the ants would choose coke was also rejected. The sugar concentrate was not a huge factor. A way to better our lab is to use things not so sticky (syrup, candy) in order to get better results, and better petri dishes to contain ants.
