How to perform scientific experiment
You notice something, and wonder why it happens. You see something and ponder what causes it. You want to know how or why something works. You ask questions about what you have seen.The first step is to write down what you have noticed.
Find out about what you want to investigate. Read books, magazines, search internet or ask professionals who might know in order to learn about the effect or area of study. Keep track of where you got your information.
TITLE THE WORK
Choose a title that describes the effect or thing you are investigating.
AIMS & OBJECTIVES OF YOUR EXPERIMENT
What do you want to find out? Write a statement that describes what you want to do. Use your observations and questions to write the statement.
Make a list of answers to the questions you have.Hypothesis must be stated in a way that can be tested by an experiment.
DESIGN AN EXPERIMENTAL PROCEDURE TO TEST YOUR HYPOTHESIS
Design an experiment to test each hypothesis.
OBTAIN MATERIALS AND EQUIPMENT
Make a list of the things you need to do the experiments, and prepare them.
PERFORM THE EXPERIMENT AND RECORD DATA
Do the experiment and record all numerical measurements made. Data can be amounts of chemicals used, how long something is, the time something took, etc. If you are not making any measurements, you probably are not doing an experimental science project.
RECORD YOUR OBSERVATIONS
Observations can be written descriptions of what you noticed during an experiment, or problems encountered. Keep careful notes of everything you do, and everything that happens. Observations are valuable when drawing conclusions, and useful for locating experimental errors .
Perform any math needed to turn raw data recorded during experiments into numbers you will need to make tables, graphs or draw conclusions.
Summarize what happened. This could be in the form of a table of numerical data or graphs. It could also be a written statement of what occurred during the experiments.
Using the trends in your experimental data and your experimental observations, try to answer your original questions. Is your hypothesis correct? Now is the time to pull together what happened, and assess the experiments you did.
Other Things You Can Mention in the Conclusion are:
If your hypothesis is not correct, what could be the answer to your question?
Summarize any difficulties or problems you had doing the experiment.
Do you need to change the procedure and repeat your experiment?
What would you do different next time?
List other things you learned.
