WHY DO SCIENCE FAIR PROJECTS WITH KIDS?

If your school has a science fair, it just might be optional. If it is, why should you help your kids do a science fair project? What’s the point? When families are so busy, why add the extra burden of science experiments?

Science fairs provide an amazing experience for kids to really dive into science and celebrate it, as well as learning something new about the world. In addition to the creative side of science, a science fair project is a fun way for kids to bond with other family members as they do their presentations. As children get older, it’s more and more important for them to be able to work through a long process like a science fair project, and these science presentations are one of the first opportunities children have to bring learning to life in such a vivid way.

WHAT IS THE VALUE IN A SCIENCE FAIR PROJECT?

When kids are involved in science fair projects, their confidence soars. Kids who do science projects report a greater confidence and understanding of all scientific concepts, both in what they explored and the scientific process in general. Learning to analyze and explore data in this way also helps children approach other tasks in a logical, straightforward process which helps improve study skills and communication skills for other subjects as well. One of the most surprising values that science fair projects bring is the ability to identify problems and work toward a solution. That is an invaluable skill that kids can use throughout life.

WHAT CAN KIDS LEARN WITH A SCIENCE FAIR PROJECT?

Kids learn a lot when completing a science fair project.

Of course, kids learn the basics of whatever scientific concept they are learning, plus the scientific method:

Hypothesis
Research
Testing
Variables
Retesting
Analyzing and Recording Data

But more than that, kids can lean additional valuable skills when completing science fair projects, including:

Presenting an idea
Creating a presentation
Organizing data
Analyzing data
Patience and orderliness
Working with others
Precision and care
Adapting to changes
Communication skills

These skills are important far beyond the classroom!
