Why should the metals be cleaned with emery paper before the start of the experiment?
Metals should be cleaned with emery paper before the start of an experiment to remove any surface contaminants, oxidation, or debris that could interfere with the results. This ensures a uniform surface that promotes better adhesion, accurate measurements, and reliable reactions. Additionally, cleaning the metal helps to achieve consistent conditions across all samples, which is crucial for reproducibility and validity in experimental outcomes.

Don came up with the hypothesis that butterflies prefer to eat nectar from white flowers. Don conducted an experiment and learned that his hypothesis was not correct. What should Don do next?
After finding that his hypothesis was incorrect, Don should analyze the data from his experiment to understand why the results differed from his expectations. He can consider other factors that might influence butterfly preferences, such as flower color, scent, or environmental conditions. Based on these insights, Don should refine his hypothesis and design a new experiment to test this revised idea. Finally, documenting his findings will contribute to the scientific understanding of butterfly behavior.
Can a hypothesis still be right even if the experiment says it is wrong?
Yes, although if the experiment is performed correctly there should be relatively little chance of this occurring. This is referred to as a type II error in statistics - the data supports rejecting the hypothesis even though the hypothesis is correct.
