The Scientific Process for Science Fair Projects

The Scientific Process for Science Fair Projects

The process that you are about to embark upon is a one that may seem overwhelming at first glance. However, the Scientific Process, when taken one step at a time is very manageable and will guide you through your project rather than slow you down. In this article I will describe many of these steps key elements.

                In my research, I came across a list entitled ‘Scientific Process’ in a book entitled How to do a Science Fair Project by Salvatore Tocci. While each project may not incorporate every single item in this list, it will likely include most of them. If nothing else this list will prevent you from missing a key element to your project just by asking ‘is this something my project requires. Okay, so here is the list:

1.       Making Observations

2.       Forming Hypotheses

3.       Conducting Experiments

4.       Recording Data

5.       Making Measurements

6.       Modifying Hypotheses

7.       Conducting Interviews

8.       Making Models

9.       Reviewing the Literature

10.   Making Inferences

11.   Drawing Conclusions

12.   Verifying Results

13.   Communicating Findings

14.   Sharing Information

Almost all of these items are self-explanatory except ‘Making Inferences.’ Inferences are conclusions that are not based on direct evidences or observations but rather on indications or logical reasoning. For example, if you light a candle, your observation is ‘that a colorless liquid collects near the wax.’ The inference would be to say that the liquid is melted wax (because it is the logical explanation). One other note must be mentioned at this point, and that is that your project should be done using the metric system. Metric is the universal measurement system adopted by the scientific process.

     The very first thing that you must determine when starting a Science Fair Project is what your hypothesis will be.  A hypothesis is an educated guess or assumption. It will be a proposal for solving a specific problem. Note that it is not necessarily an actual solution to the problem. That is what you will find out as you do the research. The hypothesis is an idea that may or may not answer a question or solve a problem but that is likely to, according to your initial investigation. A hypothesis should be clear, concise and specific. Try to state your hypothesis in one sentence. It is also important to note that your hypothesis should be testable with the resources and knowledge that you have or have access to.

     The next and most important step in creating a Science Fair Project is the experimentation. Your experiments should be as simple as possible and direct. The more complex the experiment the more likely errors will occur and conclusions will be hard to determine. Also, always be sure to include a ‘control.’ Set up your experiment with multiple items of the same object. Keep everything about each of these items the same except for one variable. This variable is the one you are testing (ie – variable A had better results/growth than variable B, etc). Again keep one of these identical items without changing any variables to use as your control.

     The last two steps are to analyze results and draw conclusions. When analyzing results be sure to only use the information obtained from your experiments. It is also very crucial that you allow the results to determine theories rather than having a theory and trying to find a way to get your results to support it. The final step is drawing conclusions. The primary conclusion you should make is if the data collected supported or rejected the hypothesis. It is very important to note that if your data does not support your hypothesis, then your project is not failed. In fact, the thing that makes a project fail, is failing to produce any conclusions. The point of the entire project is to determine whether or not your educated guess (hypothesis) was true or not, not that your guess was right.

In this video, you’ll see how to modify the rocket to make the altimeter fit. … Model rockets altimeter mounting science fair projects

Help answer the question about Science Fair Projects

Science fair projects using plants or insects ?
I'm trying to help my son who is in 8th grade think of an awesome science fair project. We have googled ideas but nothing has stood out so far. We prefer to do a project with plants or maybe insects. We looking for a science fair project that is grade appropriate if not even above grade average and we want to do something that is different and actually look like some work went into it (which we plan to do). If anyone has any legimitate suggestions let me know. Remember, I've already googled and been to the library so please don't make that suggestion.

  2. Copper pipe wouldn't be my choice because copper is so soft (the notes will not resonate well). Electrical conduit is cheaper and sounds good. A tube with thicker walls than conduit will resonate longer and probably have cleaner sound. Copper will work, though, if you already have it.

    It is important to understand how to suspend the tubes that make the different notes. If you support the tubes at the ends they will not sound very good at all. You need to support them at their nodal points, which will be located about 1/4 of the tube's length from each end.

    There is science content all the way along. You can talk about the relationship of tube length and metal thickness to the pitch and tone of the sound. You can talk about resonance and nodal points. You can talk about how musical scales relate to frequency and you can talk about different types of musical scales. Probably a dozen other inroads for science in this type of project as well.

    Here's a link to a site that discusses nodal points:
