A scientist working in a lab has tested his hypothesis and determined that it cannot be supported by the data obtained. Which of these BEST describes what he should do next in his scientific process?

• He should test the hypothesis again using the precise same experimental design conditions.

• He should revise the hypothesis to match his results and report that his hypothesis was supported.

• He should completely disregard the hypothesis and start over from scratch because his research and data is useless.

• He should look at the data and research, modify his hypothesis, and test the modified hypothesis using a new experimental design.

How do the carbon cycle, the oxygen cycle, and the water cycle demonstrate the law of conservation of matter?

• They do not demonstrate the law of conservation of matter.

• They all show different amounts of matter as it is used up in the system.

• They all show matter changing form but the total amount of matter does not change.

• They all show that animals are using the matter so it always becomes new energy.
