Write a scientific question for the experiment. Be sure to include the independent and dependent variable in your question.
A) How does drinking coffee affect blood pressure compared to drinking tea?
B) What is the average blood pressure of the participants in each group after 60 days?
C) Does 500 mL of coffee daily increase blood pressure more than 500 mL of tea daily?
D) How long does it take for blood pressure to stabilize after changing beverage intake?
The best scientific question for your experiment is:
C) Does 500 mL of coffee daily increase blood pressure more than 500 mL of tea daily?
Explanation: This question clearly identifies the independent variable (the type of beverage consumed: coffee vs. tea) and the dependent variable (the effect on blood pressure). It sets up a direct comparison between the two beverages regarding their impact on blood pressure levels, which is essential for conducting your experiment. If you have more questions or need further clarification, feel free to ask!
