Test Your Hypothesis by Doing an Experiment Analyze Your Data and Draw a Conclusion Communicate Your Results Following the scientific methodwe come up with a question that we want to answer, we do some initial research, and then before we set out to answer the question by performing an experiment and observing what happens, we first clearly identify what we "think" will happen. We make an "educated guess. We set out to prove or disprove the hypothesis. What you "think" will happen, of course, should be based on your preliminary research and your understanding of the science and scientific principles involved in your proposed experiment or study.
A hypothesis is a tentative statement that proposes a possible explanation to some phenomenon or event. A useful hypothesis is a testable statement which may include a prediction. When Are Hypotheses Used? The key word is testable.
That is, you will perform a test of how two variables might be related. This is when you are doing a real experiment. You are testing variables. Usually, a hypothesis is based on some previous observation such as noticing that in November many trees undergo colour changes in their leaves and the average daily temperatures are dropping.
Are these two events connected? Any laboratory procedure you follow without a hypothesis is really not an experiment. It is just an exercise or demonstration of what is already known.
How Are Hypotheses Written? Salt in soil may affect plant growth. Plant growth may be affected by the color of the light.
Bacterial growth may be affected by temperature. Ultra violet light may cause skin cancer. Temperature may cause leaves to change color. However, their form is not particularly useful. Using the word may does not suggest how you would go about proving it.
If these statements had not been written carefully, they may not have even been hypotheses at all. One way to prevent making such easy mistakes is to formalize the form of the hypothesis. If the incidence of skin cancer is related to exposure levels of ultraviolet lightthen people with a high exposure to uv light will have a higher frequency of skin cancer.
If leaf color change is related to temperaturethen exposing plants to low temperatures will result in changes in leaf color.
Notice that these statements contain the wordsif and then.A good hypothesis defines the variables in easy-to-measure terms, like who the participants are, what changes during the testing, and what the effect of the changes will be.

A hypothesis is a prediction of the outcome of a test. It forms the basis for designing an experiment in the scientific method.A good hypothesis is testable, meaning it makes a prediction you can check with observation or testing. A Strong Hypothesis Email. Print.
By Science Buddies on This formulaic approach to making a statement about what you "think" will happen is the basis of most science fair projects and much scientific exploration. A look at the work of Sir Isaac Newton and Albert Einstein, more than years apart, shows good hypothesis-writing in.
A good hypothesis has the following three characteristics: It is theoretically grounded: it is based upon literature relevant to the topic.
It specifies the relationship between the values of two or more variables. I am supposed to write a hypothesis about how much adipogenesis was produced after the inducement of insulin.
However, after proceeding with the experiments the results were On/Off.. meaning it will increase, decrease, increase, etc.. so it wasnt a constant result.
