The scientific method (Scientific Method) with the following details
1.I noticed and identified important issue that the problem must consider that the problem occur? The problem stems from the observation, observation is the property of a scientist. Observation may start from the environment around us.Or the growth of organisms, even Alexander Fleming
.(Alexander Fleming) was observed on the growth of bacteria in Petri dish. Found that if the mold Penicillium (Penicilliumnotatum). In the plate cultured bacteria will not thrive well, the result of observation of Alexander flame technique.Observation is the first important leads to some facts and is cause trouble. Observations should observe carefully thorough. Therefore, the great problem should stay in a manner possible.And based on the fact that various collected sample observation "grass under a big tree. Or the grass beneath the roof usually do not grow. The grass in the vicinity at the light grows good "example set problem.The problem is more important than problem solving. "Because the problems and clear, will make the problem is understanding and to see the potential of the search for the answer to resolve the location.When did this happen??
where did it happen? What's going on? Why is it so?
2.The hypothesis, hypothesis is the answer is possible. An acceptable answer is correct and reliable. When the proof, or check out several times, the best hypothesis should look as follows:
-. A hypothesis that is easy to understand!- a hypothesis suggested avenues to investigate
- a hypothesis test by experiment
- a hypothesis consistent. And within the boundaries of the facts observed and relative problems of set
.The hypothesis must be based on the main problems are always should set up several hypotheses to the guidelines of คำตอบหลาย. But not based on any one hypothesis hypothesis Is the answer before the proof testing the hypothesis of several ways, and many times. 3
.The experiment tests the hypothesis (collection of data) when the hypothesis, or guess the answer several answers, and the scientific process. The next step is the monitor hypothesis.Due to a good hypothesis has suggested avenues, investigation and design, monitoring, and how to check the hypothesis by observation and collected many facts Any resulting from natural phenomena, another method by experiments.The research data. Gather information to check to see if any hypothesis is the correct answer. In the investigation by experiment. Should be identified to the actual experimental process There should be a planned protocol.Design of experiment results well. The use of materials, chemicals and tools. There. คุมดูแล. Be careful, in the analysis of the data should be analyzed to find out the conclusion? The scientific experiment.Tester will need to control the factors affecting the experiment called variable (Variable) is what influence the experiment. Which should have the least variable variable type is divided into 3
.1) variables (independent variables) (Independent variable) is variable to study the check and see the results. The variable that we set up. A variable that is not in control of any variable
.2) variables (Dependent variable) is variable with no freedom in itself. Changes to the independent variables. Because, as a result of independent variable
.3) control variables (Controlled variable) mean other things besides the independent variable. The experiment error but we controlled constant throughout the experiment. Because don't study
.In testing the hypothesis. In addition to control the factors affecting the experiment. To break a series of experimental control group
- group means group we apply effect of independent variables
.- control refers to a series of experiments using a reference standard. To compare the data obtained from the experiments. The control group is different from the experimental group only 1 variable only is variable, we check หรือตัวแปร free.Must be record data from observation or experiment. The information obtained the set of information and meaning. Which has to be designed to save the data to read, easy to understand, may save the picture book, graphs, charts, or.
.4.The data analysis stage the data from observation, research, experiment, or gather information or facts have been analyzed. Explain the meaning of the facts. And compared with the hypothesis.
.5.The conclusion is the summary from the experiment. The research data. Summary data from observation or experiment that the hypothesis of any right. The theory building to use as a guideline for explaining a phenomenon.And the study of human life better. The conclusion is that the sun is associated with the flourish of grass and can bring the result in this application in plants. That is.Can make plants grow well
