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.
What is a hypothesis? A hypothesis is sometimes described as an educated guess. That's not the same thing as a guess and not really a good description of a hypothesis either.
Let's try working through an example. If you put an ice cube on a plate and place it on the table, what will happen? A very young child might guess that it will still be there in a couple of hours. Most people would agree with the hypothesis that: An ice cube will melt in less than 30 minutes.
You could put sit and watch the ice cube melt and think you've proved a hypothesis. But you will have missed some important steps. For a good science fair project you need to do quite a bit of research before any experimenting.
Start by finding some information about how and why water melts. You could read a book, do a bit of Google searching, or even ask an expert. For our example, you could learn about how temperature and air pressure can change the state of water.
Don't forget that elevation above sea level changes air pressure too. Now, using all your research, try to restate that hypothesis.
An ice cube will melt in less than 30 minutes in a room at sea level with a temperature of 20C or 68F. But wait a minute. What is the ice made from?

What if the ice cube was made from salt water, or you sprinkled salt on a regular ice cube? Time for some more research. Would adding salt make a difference?
Turns out it does. Would other chemicals change the melting time? Using this new information, let's try that hypothesis again. An ice cube made with tap water will melt in less than 30 minutes in a room at sea level with a temperature of 20C or 68F.
Does that seem like an educated guess? No, it sounds like you are stating the obvious. At this point, it is obvious only because of your research.
You haven't actually done the experiment.
Now it's time to run the experiment to support the hypothesis. A hypothesis isn't an educated guess. It is a tentative explanation for an observation, phenomenon, or scientific problem that can be tested by further investigation. Once you do the experiment and find out if it supports the hypothesis, it becomes part of scientific theory.Oct 30, · To write a good lab conclusion in science, start with restating the lab experiment by describing the assignment.
Next, explain what you were trying to discover or figure out by doing the experiment. Then, list your results and explain how they confirmed or did not confirm your hypothesis%().
The Three-Step Process. It can quite difficult to isolate a testable hypothesis after all of the research and study. The best way is to adopt a three-step hypothesis; this will help you to narrow things down, and is the most foolproof guide to how to write a hypothesis.
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.
Writing a science fair project report may seem like a challenging task, but it is not as difficult as it first appears. This is a format that you may use to write a science project report. If your project included animals, humans, hazardous materials, or regulated substances, you can attach an appendix that describes any special activities your .
In this lesson, we investigate why scientist use a hypothesis, practice how to write a hypothesis, and learn some helpful hints for writing a hypothesis that would make Einstein proud.
In a science fair setting, judges can be just as impressed by projects that start out with a faulty hypothesis; what matters more is whether you understood your science fair project, had a well-controlled experiment, and have ideas about what you would do next to improve your project if you had more time.
