Answer:Introduction
In this experiment, the student aims to study color preference in bees by using artificial flowers with honey as a reward. The flowers used in the experiment are blue round flowers and white square flowers of the same size. The student observes that bees choose the blue flowers more often than the white flowers and concludes that bees have a color preference for blue flowers. However, there are some flaws in the experimental design that may have influenced the results.
Flaw in the Experimental Design
The student should have conducted the experiment differently to ensure that the observed preference for blue flowers is solely due to color and not influenced by other factors such as shape or texture. The correct experiment design should have included a choice between blue round and white round flowers instead of blue round and white square flowers.
Explanation of the Correct Experiment Design
The correct experiment design, where the bees have a choice between blue round and white round flowers, would allow the student to isolate the effect of color on the bees' preference. This is because the only differing factor between the two options is the color, while the shape and texture remain constant.
Reasoning
By comparing the preference of bees between blue round and white round flowers, the student can conclude whether bees have a color preference for blue flowers. If the bees consistently choose the blue round flowers over the white round flowers, it would indicate that bees indeed have a color preference for blue flowers.
Alternative Experiment Designs
While option B is the correct answer, it is worth mentioning the other options and their limitations:
- Option A (choice between blue round and blue square flowers): This design would not allow the student to determine the color preference of bees since both options have the same color. The experiment would not provide any conclusive evidence regarding color preference.
- Option C (choice between white round and blue square flowers): This design would introduce a new variable, shape, into the experiment. Therefore, the student would not be able to solely attribute the bees' preference to color. The results may be influenced by the bees' preference for a specific shape rather than color.
- Option D (the experiment was fine and does not need any changes): This option is incorrect as the experiment design should be improved to eliminate confounding variables and accurately determine the bees' color preference.
Conclusion
In conclusion, the student should have conducted the experiment with a choice between blue round and white round flowers to accurately determine the color preference of bees. This design would isolate the effect of color and provide more reliable results.
