1. Discuss why you think it is necessary to make a prediction of the outcome of your designed
experiment before you actually run the experiment. (Explain in detail)
2. Discuss why practicing scientists (e.g. you in the physics labs) need to design at least two
independent experiments to test one theory (hypothesis). (Explain in detail)
Homework Answers
1) A prediction of the experiment result is required because the prediction helps us in calculating the error in the result that we have got.
2) In scientific experiments, the chance of errors is large. So, reproducibility is one of the qualities the theory should have. The theory must reproduce the same result at least in two scientific models to confirm its existence.

1. How do the terms hypothesis and theory differ in meaning and application? 2. Why do you think physical scientists, such as those working in the fields of physics, chemistry, astronomy, etc., might say that research in the social sciences is unscientific? 3. What materials can a researcher provide others with in order to help them replicate a study? 4. How can applied research help you understand an issue your university or community is currently facing? 5. Identify three ways in which a study might...

I will be negalite control a positive control * Homework before The Hill Reaction Lab, your group should do the following: 1) Write a question that you would like to answer about how different conditions alleet the Hill reaction. Remember, a possible answer to this question should be your hypothesis, not predictions about the specific outcome of an experiment Here is an example: Question: Is there a specific temperature range within which photosynthesis can continue to operate? Hypothesis: There is...

Use the following hypothetical situation to answer the Part C. questions. You live along the Paulinskill River in a rural area of New Jersey known for its growing agriculture industry. This area was also once known for its large bog turtle population. In the last few decades, however, the bog turtle population has decreased to the point that this species is now considered critically endangered. You want to design an experiment to aid in the recovery of the bog turtle...

PHYSICS: Can someone help me identify a concept/hypothesis and possible experiment to run? THis is supposed to be a mock experiment and not an actual lab completed. Look around and find a certain pattern. Describe the pattern / phenomena that you have selected. Pretend that you have just performed your observation or observational experiment. You may need to repeat the observation at a later time, if there is a possibility. Illustrate it with a photo or a sketch. Devise a...
