Science Fairs

Need an idea for a science fair project? Look no further! Water is not only a necessary part of our lives, it is unique and interesting substance scientists are still studying today. Here are some possible ideas for science experiments and how to go about setting one up:

Project

First off, you need to know how to get started. Scientists use something called the “scientific method” to conduct any experiment. It is a simple 6 step process you can follow too! Ready? Let’s begin:

1. Idea
Pick a topic that you are interested in, already know a little bit about, and would like to know more (like water!) If you’re having trouble coming up with an idea, check out these.

2. Research
Do a little research to find out more, and come up with a specific question you want to answer--the more specific the better.

3. Come up with a Hypothesis
The hypothesis is your guess at the answer to your question. It is ok for your hypothesis to be wrong, that is all part of the scientific method!

4. Testing
Come up with an experiment to test your hypothesis. You will need to have a purpose to your experiment and procedures for carrying it out. You will also need to know what variables you want to control and which you want to change. Record what you did, what you measured, what happened using pictures, sketches, notes, samples, or videos even if it’s NOT what you expected. Unexpected results can often lead to even more interesting conclusions.
 
5. Results
Analyze your data. Figure out if your results agree with your hypothesis. If not, can you think of another experiment to explain why? If it did, what does that mean?

6. Conclusion/Report
After looking at your data, come to a conclusion or an answer to your original question. Finish by writing a report or preparing a presentation explaining what you did, how you did it, and what you discovered. Use pictures, charts, graphs, and samples if it will help explain your results.

Ideas:

  • Why does salt make ice dissolve faster?
  • Why does ice float?
  • Why does sugar dissolve more easily in hot water than cold water?
  • How much water does it take to get an apple from the seed to the store?
  • How much water does your house use in one day?
  • What happens if you drink water from the same bottle over and over again without washing it?
  • What type of water leaves the biggest spots on your dishes and why (try different faucets and bottles)?

Schedule

Now it’s time to show off your science. Below are some of the regional and state fairs in the area. Be sure to check with your teachers to see if your school hosts one too.

  • Great Falls Fair (Great Falls, MT). March
    Grades 6-12

  • Hi-Line Fair (Havre, MT), March
    Grades 6-12
