Observations can lead to hypotheses that can lead to new experimentation. Which best describes an observation and hypothesis that could lead to new experimentation?
A.Dr. Cooper invents a machine that allows him to see atoms inside of matter with more detail. While studying an atom, he thinks he starts to see a pattern in its movement even though current theory states that atoms move in random motion.
B.Dr. Gupta is studying electron attraction by watching how two electrons are drawn towards each other by gravity. He then finds that they push away from each other when they both have a negative charge.
C.Dr. Snyder finished her investigation on particle physics. She concludes that there are eighteen types of elementary particles.
D.Dr. Abdallah is writing a paper on the theory of evolution. To do so, she interviews several evolutionary scientists.

A.Dr. Cooper invents a machine that allows him to see atoms inside of matter with more detail. While studying an atom, he thinks he starts to see a pattern in its movement even though current theory states that atoms move in random motion.

Explanation:

When Dr. Cooper invented a machine that allows him to see atoms within matter in more detail, he is making an observation. This observation will allow Dr. Cooper to create a hypothesis about what he is observing.

The hypothesis that Dr. Cooper created is represented by the excerpt: "While studying an atom, he thinks he starts to see a pattern in its movement" .

Finally, Dr. Cooper creates a theory based on observation and hypothesis that he did earlier. The theory is represented in the excerpt: "even though current theory states that atoms move in random motion."
