The correct sequence for Amina to follow in her experiment to determine which household item has the greatest acidity should be as follows:
State the problem (D): Begin by clearly defining the problem or objective of the experiment. In this case, it is to determine which household item has the greatest acidity.
Gather information (B): Before conducting the experiment, gather relevant background information about the household items you are testing, safety precautions, and any other relevant data.
Form a hypothesis (A): After gathering information, make an educated guess or hypothesis about which household item you think will have the greatest acidity. This is your prediction based on your research.
Perform the experiment (C): This is where you actually conduct the experiment, test the household items for acidity, and record your observations.
Analyze the data (E): After completing the experiment, analyze the data you collected. Compare the acidity levels of the household items to determine which one has the greatest acidity.
So, the correct sequence is D, B, A, C, E.
