Judging a Science Fair- How Do They Do It?

How are science fairs judged?  Knowing how they will be judging a science fair makes a difference!

blue ribbon projectKnowing how your science fair project is going to be judged can be really helpful as you know the things that they will be looking for as they go around judging a science fair project.

Here is how judging a science fair works in most elementary school science fairs:

A rubric is developed based on the goals and the specific  points in the assignment.

Usually this involves five different areas, that cover the whole process, not just the final presentation.  So the early steps of making a science fair project get equal credit

Example of what five areas a science project will be judged on:

  • Hypothesis– Is it written to reflect a specif goal and one variable?
  • The experiment  itself– Were the directions followed, were there at least three trials were the steps followed clearly listed.
  • Conclusion drawn from data– did the conclusion come directly from the results and not from what you “know” already
  • Oral Presentation or Written Report- did the report follow the format given,  the right length, grammar, spelling etc.

Each teacher or school will have specific elements they are looking for for each step, or they might choose five different things to judge their science fair.

Scoring

Each step is worth 5 points-  so you get a score of 1-5 on eaach element.
A perfect score would be 25 points.

Sometime different people judge different part.  Like one person would judge the displays while the language Arts teacher might grade the report teacher, and a team of judges would divvy up the other three.

Some school use three judges who judge the whole project and the average of the three scores is used.  So If one student got 25 points from one, 23 from another and 22 from a third the total would be 70, divide by 3 and you get a  23.33 for your average

Other schools use the same rubric, but it is what the teacher uses to give the project a grade, and there is not real judging or prizes awarded. A good science fair project will have all the elements there and ready to go.

Before worrying about judging a science fair, you need a great project that is kid tested and teacher approved!

We have  lots  great projects  through this link, some can be finished in one day!

Science Projects For Students- The Long and Short of It

Some science projects for students take a LONG time, others  can be short and quick.  Both can be cool!

When it comes to finding, and then doing science projects for students to use for a science fair, the first you tend to think of is time consuming with weeks of collecting data. There are really cool and simple science fair projects that involve some time, and there are also some project equally as cool that can be done in one weekend, and believe it or not there are last minute projects that can be done in one day.

The key is with most of the best science projects for students is to keep it simple and use materials easily found at home or with a quick trip to a local store. The science concepts involved can be as complicated as you want, but you are better off with a simple, particularly if there is any hope of the child doing this on their own.

Here are three examples of simple, science projects for students that can be done over time, in a weekend and on one day.

Science projects that need some time

 

I recently read an article about a girl who looked at bread mold and how different preservatives used in bread, affect how long it takes for mold to grow, or if it even grows. You can see that it is simple, all you need is some bread with different preservatives, and I am thinking a warm moist environment? It will be cool because it will become pretty disgusting, or pretty if you are into colors of mold, but it is also something that can be measured easily over time. How much mold grew, how many days before it grew and so on. This is kind project that turns into a family project. But would never work at the last minute.

Science projects for students to do in a weekend

When you have a weekend, the actual project can be fairly quick, usually it means track data over several hours, or overnight. But you have the whole weekend to organize, and get the write-up or  display put together so it looks good.  One popular project is looking at insulation and seeing what works best. This works well as it seems like a popular topic with the push for more green technology.

 

One Day Science Fair projects can be cool too.

Not only are these great for the last minute when you did not realize a project was so, we’ve all been there, but they can work well for a quick homework experiment that may not mean making a big display for a science fair. Keeping with the green theme, you can quickly analyze which toilet paper is most biodegradable.
You can see all of these science projects for students use easy to find materials, are things the kids can do themselves, but the family can also get interested in which can help motivate the kids and keep interest alive.
