Science Fair Project Background Research Plan
Key InfoBackground research is necessary so that you know how to design and understand your experiment. To make a background research plan — a roadmap of the research questions you need to answer — follow these steps:
- Identify the keywords in the question for your science fair project. Brainstorm additional keywords and concepts.
- Use a table with the "question words" (why, how, who, what, when, where) to generate research questions from your keywords. For example:
What is the difference between a series and parallel circuit?Throw out irrelevant questions.
When does a plant grow the most, during the day or night?
Where is the focal point of a lens?
How does a java applet work?
Does a truss make a bridge stronger?
Why are moths attracted to light?
Which cleaning products kill the most bacteria?
- Add to your background research plan a list of mathematical formulas or equations (if any) that you will need to describe the results of your experiment.
- You should also plan to do background research on the history of similar experiments or inventions.
- Network with other people with more experience than yourself: your mentors, parents, and teachers. Ask them: "What science concepts should I study to better understand my science fair project?" and "What area of science covers my project?" Better yet, ask even more specific questions.
Why the Need for Background Research?
So that you can design an experiment, you need to research what techniques and equipment might be best for investigating your topic. Rather than starting from scratch, savvy investigators want to use their library and Internet research to help them find the best way to do things. You want to learn from the experience of others rather than blunder around and repeat their mistakes. A scientist named Mike Kalish put it humorously like this: "A year in the lab can save you a day in the library."
Background research is also important to help you understand the theory behind your experiment. In other words, science fair judges like to see that you understand why your experiment turns out the way it does. You do library and Internet research so that you can make a prediction of what will occur in your experiment, and then whether that prediction is right or wrong, you will have the knowledge to understand what caused the behavior you observed.
Making a Background Research Plan: How to Know What to Look For
When you are driving a car there are two ways to find your destination: drive around randomly until you finally stumble upon what you're looking for OR look at a map before you start. (Which way do your parents drive?)
Finding information for your background research is very similar. But, since libraries and the Internet both contain millions of pages of information and facts, you might never find what you're looking for unless you start with a map! To avoid getting lost, you need a background research plan.
The place to start building your background research plan is with the question for your science fair project (see, we did that first for a reason). Let's imagine that you have asked this one:
Begin by identifying the keywords and main concepts in your question. In this case keywords would be:
That's pretty easy! Now, what might be some of the main concepts that relate to these keywords? Let's think about spiciness first. You're going to do a science experiment, so knowing that a spicy food tastes "hot" is probably not sufficient. Hmmmm, this is a little tougher than finding the keywords.
Question Words Table
The secret is to use the "question words" (why, how, who, what, when, where) with your keywords. Ask why things happen, ask how things happen, ask what causes things to happen, ask what are the properties of key substances. Filling in a little table can help. Let's do it for our keyword spiciness:
|Question Word||Fill Your Keywords (or Variations on Your Keywords) into the Blanks
These are just samples to get you thinking; there are always many more questions and the most important ones for your project may not be in the list!
|Possible Questions for Background Research||Relevant?|
|Why||Why does ________ happen?
Why does ________ ________?
|Why does spiciness happen?
Why do spicy foods taste hot?
|How||How does ________ happen?
How does ________ work?
How does ________ detect ________?
How does one measure ________?
How do we use _________?
|How does the tongue detect spiciness?
How does one measure spiciness?
|Who||Who needs ________?
Who discovered ________?
Who invented ________?
|Who needs spiciness?||No|
|What||What causes ________ to increase (or decrease)?
What is the composition of _________?
What are the properties and characteristics of ________?
What is the relationship between _______ and ________?
What do we use ________ for?
|What causes spiciness to increase (or decrease)?
What are the properties and characteristics of spicy substances?
|When||When does ________ cause ________?
When was _______ discovered or invented?
|When does spiciness cause upset stomachs?||No|
|Where||Where does ________ occur?
Where do we use ________?
|Where in the body does spiciness occur?||Yes|
Those look like pretty good questions to research because they would enable us to make some predictions about an experiment. But what's that column in the table called "Relevant?"
You can always find more information to research, but some questions just don't have anything to do with the experiment you will define and perform. Questions that will help you design and understand your experiment are called relevant. Questions that will not help you design and understand your experiment are called irrelevant. Our table of question words is a great way to generate ideas for your background research, but some of them will be irrelevant and we just throw those out. Some of those irrelevant questions might be very interesting to you; they just don't belong as part of your science fair project. We have to focus our efforts on what we feel is most important, or another way of looking at it, let's not spend time researching anything we don't need to. (I'm sure you have other things you'd like to do, too!)
For a good example of how the question word table can generate irrelevant questions, let's just look at some possible questions if we fill out the table for another one of our sample keywords: milk.
- Why does milk happen?
- How does milk happen?
- Who needs milk?
- What causes milk to increase (or decrease)?
- What is milk composed of?
- What are the properties and characteristics of milk?
- Where does milk occur?
If we research every one of those questions we'll be studying farms, cows, cow udders, baby cows, and what cows eat. Holy flying cows! That information is definitely irrelevant to our science fair project question: Does drinking milk help decrease spiciness better than water or Pepsi?
Even so, in that crazy list of cow science, there are two questions that look relevant for your background research:
- What is milk composed of?
- What are the properties and characteristics of milk?
Sometimes you won't be sure whether a question is relevant or not, and that's always a good time to get the opinion of more experienced people like your mentors, parents, and teachers. In fact, the background research plan is a very important step of your science fair project and two or three heads are always better than one! Even with all that help, you may not be sure whether something is relevant until after you have done your experiment, so don't let it bother you if that's the case.
Talk to People with More Experience: Networking
As you can see with the two above examples, spiciness and milk, the question word table will work better for some keywords than others. You might have a science fair project question where none of the keywords generate relevant questions. Yikes! What do you do then?
One of the most important things you can do is talk to other people with more experience than yourself: your mentors, parents, and teachers. This is called "networking." Some of these people will have had classes or work experience that involved studying the science involved in your project. Ask them, "What science concepts should I study to better understand my project?" Better yet, be as specific as you can when asking your question. Even experts will look puzzled if you ask a question that is so generic it leaves them pondering where to start. Instead of asking, "How do airplanes fly," try asking, "What physical forces are involved in the flight of an airplane," or "What role do propellers play in the flight of a helicopter?" (After all, there's gotta be something that causes that hunk of metal to go up, right?)
For example, let's imagine your science fair project question is: Does the velocity of a roller coaster car affect whether it falls off a loop? If you ask someone who has studied physics in high school or college, they will tell you to ask the research question, "What is centripetal force?"
Sometimes there is even a specialized area of science that studies questions similar to the one for your science fair project. Believe it or not, there are actually people who study "roller coaster physics." (Is that a cool job or what?) Often a good topic for your background research is simply the specialized area of science that covers your project. For the roller coaster example you would research "roller coaster physics."
How do you find the area of science that covers your project? You guessed it, network with your mentors, parents, and teachers. And by the way, networking is something many adults don't expect students to be very good at, so you can probably surprise them by doing a good job at it! The very best networkers, of course, enjoy the spoils of victory. In other words, they get what they want more quickly, efficiently, and smoothly.
The reality is we have all networked at some point in our lives. Remember how you "networked" with your mom to buy you that cool water gun, or "networked" with your grandpa to buy you that video game you always wanted? Well, now you are "networking" for knowledge (which is a very good thing to network for, by the way). Train yourself to become a good networker, and you might just end up with a better science fair project (and don't forget that you'll get a little smarter too in the process). So take our advice: work hard, but network harder.
