Do a Science Fair Project!
The Short Answer:
How do you do a science fair project?
Your science fair project may do one of three things: test an idea (hypothesis), answer a question, and/or show how nature works.

Ask a parent, teacher, or other adult to help you research the topic and find out how to do a science fair project about it.
Test, answer, or show?
Your science fair project may do one of three things:
Test an idea (or hypothesis.)
Answer a question.
Show how nature works.

How do the constellations change in the night sky over different periods of time?
How does the number of stars visible in the sky change from place to place because of light pollution?
Learn about and demonstrate the ancient method of parallax to measure the distance to an object, such as stars and planets.
Study different types of stars and explain different ways they end their life cycles.

Pick a topic.
Try to find out what people already know about it.
Do one of these:
State a hypothesis related to the topic. That is, make a cause-and-effect-statement that you can test using the scientific method.
Make a plan to observe something.
Design and carry out your research, keeping careful records of everything you do or see.
Create an exhibit or display to show and explain to others what you hoped to test (if you had a hypothesis) or what question you wanted to answer, what you did, what your data showed, and your conclusions.
Write a short report that also states the same things as the exhibit or display, and also gives the sources of your initial background research.
Practice describing your project and results, so you will be ready for visitors to your exhibit at the science fair.
Follow these steps to a successful science fair entry!
