Alexis Fec BIO182 Jacobs Scientific Method Qs 1. The experiment we conducted today was around the effects on emergence times of small, spongy capsule animals. Each member of our group would record the color capsule and water temperature. Then, we would drop a small capsule animal into the water and stir until the first sign of its emergence from the gelatinous coating. The color was our controlled variable. In our second trial, the water temperature was the controlled variable. Our hypothesis was that color had nothing to do with emergence times, but water temperature would speed up the process. 2. Our group predicted that the color of the capsule wouldn’t have an effect on emergence times, but the change in water temperature used would speed up the process. 3. P-value was 3.05E-7

Unformatted text preview: 4. Our hypothesis was supported. The first group did vary in times, but not by color, to show that there is no set difference between the emergence times of the green and blue capsules. In the second group, we raised the temperature of the water by 20 C. The emergence times were cut in half, if not more. 5. In conclusion, emergence times are not affected by color, as the animals are all spongy and similar enough to not differ. They are, however, affected by the temperature of the water, noting that higher temperatures correlate with lower emergence times. To make this experiment better, I would have set a precise moment to stop the timer. Even though this was attempted, it wasnt followed directly and that skewed some of the data....
