What are the steps you follow in an experiment?

Answer 1

Conducting the Experiment

• Determine what problem or question you hope to answer with your project. This question or problem should be something that could reasonably be determined through your own home-based experimentation. For instance, you can't answer a question through experimentation such as, "What is the long-term effect of alcohol on a person's liver?" But you could answer a question such as, "How does alcohol affect the growth of plants?"

  After deciding on the question, form a hypothesis, or your own educated guess, as to what the answer is. Write out your hypothesis, explaining what you expect to happen during the experiment and what the result will be. Explain the reasons behind your hypothesis

  Write the steps necessary to complete the experiment. An experiment contains control and variable factors. Control factors do not change, so that the effect of the variable factors can be observed. For instance, in an experiment to determine how alcohol affects the growth of plants, you use the same type of plants, planted at the same time, in the same type of soil, receiving the same amount of sunlight, but given different amounts of alcohol in place of water. In this experiment, the type of plants, soil, sunlight and time are all control factors while alcohol and water are variables.

  Observe the experiment's progress and keep detailed records of your observations in a journal. Take measurements and quantify the progress using numbers. For instance, during the experiment using plants and alcohol, you might notice and record differing colors or conditions of a plant's leaves, but also measure the growth of the plants using a ruler or weighing them with a scale.

  At the conclusion of the experiment, analyze your observations and use them to determine whether your hypothesis was correct. Write a conclusion describing what you found. Were you surprised by the results? Would you like to repeat the experiment? What would you do differently? Theorize about the reasons for your results.

Presenting the Project

• After you have finished the experiment, prepare a report, including your problem/question, hypothesis, experiment procedure, observations and conclusions. Write in complete sentences and present the typed report with a professional-looking cover. Include pictures taken during the experiment and create colorful graphs or charts to summarize your observations.

  For a science fair, purchase a foam core trifold board to display your report. Use color to highlight the title at the top of the project. Attendees should see at a glance your project's outcome, so concisely summarize your sections to print and glue onto the board. If the rules permit it, display portions of your experiment. For instance, bring the plants labeled with how much alcohol they received and place them on the table in front of the standing trifold board.

  If asked to give an oral presentation about your project, bring note cards with summaries of the main points of your project. Only include the most important or most interesting points about your project if there is limited time. Keep the complete report nearby in case you need to refer to it during a question and answer session. Take deep breaths and practice to calm your nerves.

Answer 2

• Ask a Question
• Do Background Research
• Construct a Hypothesis
• Test Your Hypothesis by Doing an Experiment
• Analyze Your Data and Draw a Conclusion
• Communicate Your Results

The four steps of the scientific method are observation of the phenomenon, forming a hypothesis, testing the hypothesis, and establishing a theory.
