Each science fair project usually begins with a question. The question can be the name of the project. If you are going to find out whether an egg will float in flour and water, your question will depend upon what you do in the science fair project. Some questions for different projects can be: How much flour will it take to get a fresh egg to float in a mixture of flour and water? Does a fresh egg sink faster in saltwater than it does in flour mixed with water? How much flour do you have to put in the water to make the egg not submerge in the mixture?
A hypothesis is a guess as to what you think will happen in an experiment. Many science fair projects are actually the presentation of experiments. For each experiment, you should state your hypothesis. In a science fair projects about whether an egg will float or sink in flour or water, you can write out what you think will happen to the egg by answering the questions listed in Section 1.
Most science fair projects require that you list the materials you are using. To answer the questions in Section 1, you will use different materials for each project. The materials will include measuring cups, a five-pound package of flour, measuring spoons and a box of salt.
The procedure will be the list of steps you do to perform the experiment. For a science project, write out your list of steps. For example, there will be a procedure to answer the question: How much flour will it take to get a fresh egg to float in a mixture of flour and water? It can be: mix 1 tsp flour in 1 cup water; in another cup of water, mix 2 tsp flour into 1 cup water -- repeating the procedure with more teaspoons of flour in different cups of water until the mixture is thick. The final step would be to test to see if the egg floats in each cup of water.
The observations are your record of what happened. For example, if the egg sinks in the first cup of water (which it will), then you draw the cup of water with the egg at the bottom of the cup and write a sentence about it. In the last cup of water you repeat the same thing (which will be your finding and picture that the egg floated in the mixture of many teaspoons of flour in a cup of water).
Your conclusion will be your answer to your question in Section 1. For example, if the egg floats when you put a certain number of teaspoons of flour in the water, your conclusion will be a few sentences about that and what you did to figure that out.
