Scientific question: Why does a dog circle its bed before lying down?Write the steps you would take to explore this question using the scientific method.
To explore why a dog circles its bed before lying down, first research the question by looking at existing studies on dog behavior and instincts. Next, form a hypothesis, such as “Dogs circle their bed to make it more comfortable or to mark their territory.” Then, make a prediction based on the hypothesis, like “If a dog circles its bed, it will lie down more calmly afterward.” Perform an experiment by observing several dogs in controlled conditions, noting how often and in what manner they circle their beds. Collect and analyze the data to see if the circling behavior is consistent and correlated with comfort or other factors. Finally, make a conclusion, deciding whether the data supports or rejects the hypothesis, and write a lab report summarizing the methods, results, and conclusion.

A student wonders if adding fertilizer to the soil will make tulips grow faster. The student’s hypothesis states, “If fertilizer is added to the soil, then the tulips will grow faster, because fertilizer adds nutrients to the soil.” Which of the following variables is the independent variable?
Think back to the bean plant experiment you read about earlier. The student’s hypothesis stated, “If bean plants are grown in green light, they will grow taller, because bean plants are green.” Which of the following variables is the dependent variable?
