The investigator never begins an experiment without a prediction of its outcome. The prediction is always based on the particular experiment designed to test a specific hypothesis. Predictions are written in the form of if/then statements: "lf the hypothesis is true, then the results of the experiment will be…"; for example, "if cactus spines reduce herbivory, then removal of the spines will result in greater surface area removed by herbivores." Making a prediction provides a critical analysis of the experimental design. If the predictions are not clear, the procedure can be modified before beginning the experiment. For the soybean experiment, the hypothesis was: "Exposure to sulfur dioxide reduces reproduction." What should the prediction be? State your prediction.

To evaluate the results of the experiment, the investigator always returns to the prediction. If the results match the prediction, then the hypothesis is supported. If the results do not match the prediction, then the hypothesis is falsified. Either way, the scientist has increased knowledge of the process being studied. Many times the falsification of a hypothesis can provide more information than confirmation does, since the ideas and data must be critically evaluated in light of new information. In the soybean experiment, the scientist may learn that the prediction is true (sulfur dioxide does reduce reproduction at the concentration tested). As a next step, the scientist may now wish to identify the particular level at which the effect is first demonstrated. Review your hypotheses for the numbered questions. Consider how you might design an experiment to test the first hypothesis. For example, you might measure auditory function by performing hearing tests or observing changes in structures in the ear. The prediction might be:

IF cell phone usage reduces auditory function (a restatement of the hypothesis),

then people who use cell phones will score lower on hearing tests than persons who do not (predicting the results from the experiment).

Now consider an experiment you might design to test the second hypothesis. How will you measure "mental advantage"?

State a prediction for this hypothesis and experiment. Use the if/then format:

The actual test of the prediction is one of the great moments in research. No matter the results, the scientist is not just following a procedure but truly testing a creative explanation derived from an interesting question.​

1. Honeybees provide 80% of the pollination services for crops, including almonds, squash, melons, alfalfa, apples, and pumpkins. Migratory beekeepers transport over 2 million hives to farmland as crops begin to flower. In 2006-2007 beekeepers were alarmed when 50% of the honeybee colonies in 26 states were lost. In fact one of the biggest mysteries was that the bees were not found dead in the hives, but rather were simply gone! Scientists have termed this Colony Collapse Disorder (CCD). They are currently considering three alternative hypotheses: emerging pathogens (viruses, bacteria, and/or fungi), environmental toxins or chemicals; or abduction by humans (or aliens). Using the criteria in Lab Study B, Developing Hypotheses, select the hypothesis you would pursue as a scientist and justify your choice.

Help with genetics question. I need explanation for answers. My prediction is: I would predict that one allele is producing two mRNAs, one normal and one abnormal. And the other allele is producing one mRNA of abnormal size.

I need help what kind of test can be done to prove this.

A child has been admitted to your hospital with low blood O2 levels. A test for β thalassemia (a Northern blot) was done using a standard probe for β globin mRNA. This blot gave three different bands, indicating the patient has mRNA of three different sizes: one larger than normal, one smaller than normal, and one normal. The parents of the patient are both from Mediterranean countries but there is no reasonable chance that they are related.

a. Devise a hypothesis for the genotype of the child that explains how their genotype gives β thalassemia and also three different sizes of mRNA.

b. Devise a test (or tests) that will determine if your hypothesis is correct.

c. What results would you predict your test would give if your hypothesis is correct.

Scientific Method Exercise
Identify a situation in which you applied the scientific approach to solving a problem. Share your thinking! The problem you choose to write about can be very simple, such as: my flashlight won't work, or my car won't start, or I baked muffins and they were flat ( didn't rise properly) , or the toilet won't flush properly, or better yet, think of your own. These probably don't sound like "science" problems, but it is most likely that you would use the scientific method to solve them, without even realizing it. Avoid using people problems and child or pet behavior issues as your "problem." Follow these steps to create your first writing assignment:

1. Describe the situation and your observation,
2. Describe your hypothesis to explain the observation.
3. Describe your further observations or experiments to test the hypothesis. Be sure your hypothesis is one that can be tested. Consider what you might use for "controls".
4. Was the hypothesis correct? If not, can you find a better one? Or do you need a better experiment? If so, what would it be?

The assignment should be formatted as follows: Be sure to include the labels, so it is clear that you recognize and identify each step in the process.
Problem: (briefly describe your problem here)
Question: (This may be a "how" or "why" question that you will formulate a tentative answer to. Your tentative answer is your hypothesis.)
Hypothesis: (State the answer to your question above. This is your "best guess" regarding the answer to the question.)
Prediction: (This describes your experiment very briefly and states the outcome you expect that would support your hypothesis)
Experiment: (Describe how you tested your hypothesis)
Results: (Describe what happened, and whether the results supported or failed to support your hypothesis)
