A scientific method is a step by step process on how to find out something. For example, which will grow the tallest, the tomato plant with the fertilizer? Or the tomato plant with the compost? -But they have to have the same amount of soil and water, and light, also this is called a control variable. Also a variable is something change like one plant has 70ml of water and the other has 80ml of water the variable is the water. A **fair test** occurs when you change only one variable and keep all othes the same.

First I would make a hypothesis, which is an educated guess. Such as, “I think the tomato with the compost will grow the tallest.” Then I would make an experiment to see if my hypothesis was correct.

Then I would make some observations while the experiment is going on. An observation is whats happening or what it looks like “The plant with the compost is grew 18.6cm and plant with the fertilizer grew 17.9 cm.”

Then after the experiment is done, I would do some research to see why the plant with the compost grew the tallest.

Then I would do the test again, do the same thing. Same water, and same amount of soil, and same amount of daily water.

Then make more observations. Then the compost plant grew 18.3cm and the fertilizer grew 18.1cm. Then once more time. This time the fertilizer grew 17.8, and the compost grew 18.9cm.Then I would make a chart to show how the plants did, and find the average. For Example:
 * || 1st Try || 2nd Try || 3rd Try || Average ||
 * Fertilizer || 17.9cm || 18.1cm || 17.8cm || <span style="background-color: #ffff00; display: block; font-family: 'Arial Black',Gadget,sans-serif;">17.9cm ||
 * <span style="background-color: #ffff00; display: block; font-family: 'Arial Black',Gadget,sans-serif;">Compost || <span style="background-color: #ffff00; display: block; font-family: 'Arial Black',Gadget,sans-serif;">18.6cm || <span style="background-color: #ffff00; display: block; font-family: 'Arial Black',Gadget,sans-serif;">18.3cm || <span style="background-color: #ffff00; display: block; font-family: 'Arial Black',Gadget,sans-serif;">18.9cm || <span style="background-color: #ffff00; display: block; font-family: 'Arial Black',Gadget,sans-serif;">18.3cm ||

<span style="background-color: #ffff00; font-family: 'Arial Black',Gadget,sans-serif;">Then I would make a procedure because if you forget or if other Scientist wants to test it to see if the results were accurate or even just for no reason. Every step has to start with a verb.

<span style="background-color: #ffff00; font-family: 'Arial Black',Gadget,sans-serif;">For Example <span style="background-color: #ffff00; font-family: 'Arial Black',Gadget,sans-serif;">Step 1: Put same amount of soil in both pots. <span style="background-color: #ffff00; font-family: 'Arial Black',Gadget,sans-serif;">Step 2: Put seed in about 1 cm under soil. <span style="background-color: #ffff00; font-family: 'Arial Black',Gadget,sans-serif;">Step 3: Put plant somewhere where it could get light.

<span style="background-color: #ffff00; font-family: 'Arial Black',Gadget,sans-serif;">and so on. It should in have all the steps on how to do the experiment you did.

<span style="background-color: #ffff00; font-family: 'Arial Black',Gadget,sans-serif;">Then you would write a conclusion with sources of error. Sources of error is thing that could affect the experiment such as the throwing a paper airplane, the way you throw it.
