Scientific Method Who uses it? What is it? Why should I care?
Everyone uses the scientific method every day. Yes, Even You!!!!!!!
It is a series of logical steps to solve problems. Do you have any problems to solve? Any big or any small ones?
Any of these sound familiar? Where are my shoes? What should I have for lunch? What class do I have next? Did I do my homework for that class? What is the cure for cancer? Which deodorant works the longest?
There are six steps to the Scientific Method. 1. Problem/Question 2. Research 3. Hypothesis 4. Experiment 5. Analysis 6. Conclusion
By following these steps in order, you will answer your questions. Notice the IN ORDER part. It is very important.
Problem/Question This is the question that you are trying to answer or the problem you are trying to solve. Try to narrow it down and be very specific.
Research Gather data about your question: internet books magazines reports experts your past experiences
Hypothesis educated An educated guess. based A prediction based on data. What you think the answer is, based on gathered information. your gathered information.
Write the Hypothesis Say what you are going to do and then include what you expect the result to be. An IF…THEN statement is a good way to state a hypothesis. IF (what you are going to do), THEN (what you expect to happen.) Example: IF 3 types of paper airplanes are thrown, THEN the most streamlined one will fly the furthest.
Experiment This is broken into 3 parts. Materials is a list of equipment that you will need for the experiment. Procedures are a list of instructions that you need to follow for the experiment. Data collection is writing down what data you measure and what you observe. This is usually in the form of a data table.
Pictures Visual observations can be preserved with photographs. A picture is worth a thousand words!
Analysis Organize your collection of information from the experiment. It may be data tables, graphs, or written work (probably all 3!) This is figuring out WHAT HAPPENED!!!!! Use all of the above to think about, understand, and write down what happened.
Conclusion In a conclusion you explain the following: What was the answer to your question? Did the data prove your hypothesis true? It is OK if your hypothesis was not correct. Simply explain what the data shows. Report to others your findings. Think of a new question!
By following these steps in order, you will answer your questions using the scientific method. That is how you use the scientific method. You’ve been doing it all along!
