tom is conducting an investigation on plant growth. he starts with a hypothesis but changes his method after observing unexpected results. what does this indicate about his investigation?
a tom’s investigation is not scientific because he changed his method.
b real scientific investigations often require flexibility and adjustments.
c tom should have stuck to his original method to be scientific.
d scientific investigations never change once they start.

Explanation:

In scientific investigations, flexibility to adjust methods based on results is crucial (e.g., modifying procedures when unexpected data arises). Option A is wrong as changing method doesn’t make it unscientific. Option C is wrong because sticking rigidly isn’t required; adaptability is key. Option D is wrong as investigations can change. So B is correct as real scientific work needs adjusting methods.

Answer:

B. Real scientific investigations often require flexibility and adjustments.
