Science Fair for Kindergarten

Participating in a Science Fair is a great way for kids to explore the world and how things work.  Young kids are curious and love to explore heir surrounding and nature, so it’s a perfect fit.  

However, for some parents the announcement by their child that they want to participate in the school Science Fair brings an onset of stomach butterflies. Not to worry, this post should make the Science Fair journey a bit more enjoyable for everyone!

Science Fair Teach Some Valuable Lessons

  • STEM (Science, Technology, Engineering and Math) careers are growing at a fast pace with many jobs expected in the future. A Science Fair is a great introduction to the world of Science.
  • A Science Fair project includes problem solving and critical thinking skills.  It encourages kids to questions how things work. 
  • Bringing a project from an idea to a conclusion is not easy. Science Fair projects have definitive steps which helps teach kids a problem-solving timeline.  
  • Reflecting on Science Fair results helps kids to think about what happened and to consider things they could have done differently.  This gives them a real-world learning experience.
  • Participating in a Science Fair gives students the opportunity to communicate information in writing and speaking.  A good opportunity to help build self-confidence.

Friendly Science Fair Vocabulary

If your child’s Science Fair packet is already leaving you confused, don’t stress.  Here’s a list of science project terms and definitions you will help support your child’s project.

  • Hypothesis:  A hypothesis is simply an educated guess about what will happen in your experiment.
  • Materials: This is a list of exactly what you used (or plan to use) in your experiment:
  • Purpose: (Problem) Question (all mean the same thing) What does your project hope to find out.  What are you trying to test? 
  • Procedure: – A step by step description of how to do your experiment. Another person should be able to follow your procedure and be able to do the same experiment.
  • Observations: Write down any observations that you see happening.  This could be by the minute, hour, daily or longer.  Recording observations will depend on your experiment. Your information could be listed in a graph or chart.
  • Conclusion: From looking at the results, what statement can you make about what happened in your experiment and how it relates to the hypothesis. 
  • Variables – When doing a science experiment, variables are things YOU control to make good judgments about your experiment.
  • Independent variable: the thing you change in the experiment. Everything else stays the same
  • Dependent variable:  the thing that changes because of what you did (what happened because of your independent variable).

The Science Fair Board Made Easy

  • Buy a 3-sided Science Display board at a local craft store.  They are also available at a similar price at a VERY LARGE online store.
  • Buy or make headings for Science Fair– See the vocabulary terms listed for headings.
  • Use PowerPoint software to create slides to print the information. This allows kids to choose the font, design, and color.  Perfect for the young scientists that are in the early stages of writing. Also support technology skills.

Science Fair Result 

A Science Fair project can be the ultimate hands-on learning experience.  It can help kids understand scientific ideas and helps them remember the information they learned. 

Example: Miss M’s Science Fair project

  • Hypothesis:  Water will make plants grow best.  
  • Materials: 4 Primrose Plans, water, soda, iced tea, 2% milk, 4 saucers
  • Purpose: (Problem) Question (all mean the same thing) Which liquid will make the plants grow best?   
  • Procedure: Buy 4 plants of same type and of similar size.  Place plants in saucers.  Label each plant to be watered by 4 different liquids (water, 2% milk, soda and iced tea).  Put ½ cup of liquid in each saucer every 3 days.  Allow the plant to absorb the liquid for 30 minutes.  Observe plant and record observations before, during and after watering.  Look for changes throughout the project and record observations.
  • Observations: Record observations in journal and take photos of plants.
  • Conclusion: The plant watered with water grew tallest and had healthy looking leaves.  The plants watered with soda and milk died quickly.  The plant watered with 2% milk did not die but did not look as healthy as the plant only watered with water. The hypothesis was correct.   
  • Independent variable:  4 different types of liquids.
  • Dependent variablePlant growth and healthiness.   

Great Resources for Science Fair Projects

  • Google Science Fair– A resource library to support every step of the Science Fair; from idea to completed project.
  • Science Buddies – A collection of project ideas in all areas of science.  The Topic Selection Wizard tool is fantastic and can help you find a project you will enjoy!
