Community Helpers Theme for Preschool: Bubbly Fires Science Activity!

Who are the people in your neighborhood?  Exploring the jobs that helpers have in the community is FUN learning for curious kids!  Come learn and play with the #TeachECE Early Childhood Team this week as we explore all the various helpers in our own neighborhoods with a COMMUNITY HELPERS THEME.  Our own “bubbly fires” science experiment will encourage kids to use critical thinking skills while playing to learn!

Community Helpers Theme Preschool Science ExplorationCommunity Helpers Bubbly Fire Science Experiment for Preschool!

To become good scientists, kids must begin with an inquiry into a subject they wish to know more about.

Our inquiry began with one student’s question:  How do fires start?

To find out, we asked a local firefighter:

“Usually fires are a chemical reaction between oxygen in the air and some kind of fuel.  Fire is what we see when matter changes form.  All fires require fuel, heat, and oxygen. The fuel is anything that can burn. The heat can come from many things, such as a lighted match, electrical appliances, or a heating system/fireplace.  Oxygen in the air allows the fire to grow.  Fires can start under a variety of circumstances.  Many home fires start in kitchens when people are cooking.  Home fires can also be caused by unattended candles, electrical appliances, and carelessness with fireplaces or wood burning stoves…”.

Bubbly Fire Experiment for PreschoolTo explore a simple chemical reaction that is safe for kids, we made bubbly fires with vinegar and baking soda.

Materials needed:

  • Two plastic or paper cups – clear is best so the kids can see what is happening
  • Baking Soda – fill the cups 1/3 full
  • White Vinegar
  • Optional:  Food Coloring (we added yellow and a little orange to the vinegar in order to create our “bubbly fires”)
  • Optional:  Flames and Smoke (cut the flames and smoke from the free printable Smoke and Fire to attach to the plastic cups).

Invite the kids to pour vinegar slowly from one cup into the cup that contains the baking soda.  Invite the kids to observe what happens to the baking soda.   As the vinegar and baking soda are combined, a chemical reaction occurs to create a BUBBLY FIRE!

Community Helper Science Experiment for Preschool 006Our kids LOVE this experiment and ask to do it many times a year!  To further investigate and test the reactions, we have also tried:

  • Heating the vinegar slightly to see what results we get
  • Pouring the vinegar FAST
  • Using varying amounts of baking soda and vinegar

Experiment Wrap-Up:  Come together and invite the kids to share thoughts and observations.  What created the biggest “bubbly fire?”  What happened to the bubbly fire in the cup after a few minutes?  Why do you think the bubbles settled in the cup?  Discussions will open the door for enhanced language and listening skills while encouraging kids to use independent thinking skills as they share.

NOTE:  Ask a local fire department if they will donate fire hats for the kids to wear!  The experiment is special, but the hats make it officially…AWESOME!

For 100+ creative ways to encourage your own little scientists at home or in the classroom (including an extensive section on experiments with baking soda and vinegar), please see:

The Curious Kids Science Book by Asia CitroThe Curious Kid’s Science Book by Asia Citro is a wonderful collection of easy to set-up science experiments that allow kids to have fun while developing the natural curiosity they have about the world . Each exploration comes with detailed instructions, personal insights, and delightful photographs that will make science come alive for kids. As kids explore, they are compelled to use critical thinking skills within inquiry and solution-based challenges.   Kids will be able to take away new knowledge that they can then apply to problems they encounter at home, in the classroom, or in the larger community!  It is a wonderful book to add to your home or classroom resource library!

    This has to be one of our favourite science activities. My kids ask for it regularly and when I taught High School Science it was the first experiment we did every year to get them thinking scientifically.

    We love baking soda and vinegar experiments. I love that you tied it into fire safety with free printables. Great idea! We will have to try it out.
