Kiara has a red bird feeder, and her neighbor has a blue bird feeder. kiara observed that most birds go to her neighbor's blue feeder instead of her red one. she wanted to know why this happens, so she developed the following hypothesis: "if my bird feeder is blue, then the amount of birds feeding at my feeder will increase because birds prefer the color blue." to test this hypothesis, she bought a blue bird feeder. the results were the same as before she had changed the color of her bird feeder. what does this say about kiara’s hypothesis, and what should she do next?
