Bubble Science Part 2

Did you know you can learn alot from playing with bubbles?

We got to the park about a half hour before Take Action Tuesday was to start today, so we could set up our supplies for our bubble science program.

After setting up the supply table, we had one more project to make before everyone arrived.  We moved to another table and made bubble blowers out of paper cones and masking tape.  Basically you roll two or three layers of photo copy paper into a cone shape, put a small piece of masking tape on it, and trim the ends.   We made about 20 or so ahead of our guests arriving, and then had to make a few more once everyone was here.

If you would like to read about how we got ready, and put it all together, including the directions for all the science experiments, the bubble solution recipe, and the handouts we gave each child, please read Bubble Science Part 1 posted here.  We will also have a future story with more bubble science and art in Bubble Science Part 3, so be sure to check back for the conclusion on our bubble learning adventure.

My kids were so excited with anticipation.  They worked hard to get all their supplies together and made so many fun things to learn with today.  They could hardly wait for their friends to arrive.  When folks started showing up, they yelled “They’re Here! They’re Here!”  It melts my heart to see them so excited.

23 Kids ages 0 to 13 came for our program today.  We never know how many will be here because we leave it up to each family whatever fits them the best.  Some days we have 20, some days we have 40, and on one occassion we had 130.  I always pray and ask the Lord to guide the families He wants us to minister to each time.  Todays number was a perfect fit for this program.

We started off talking about “What is a bubble?” and did a demonstration with some balloons.  The kids answered lots of questions about bubbles, gas, air, and more.


We gave each child one of the paper cone bubble blowers we had made.  To use these, you gentily soak the large end in the bubble solution for 30 seconds, then on future dips you only need to dip them for 2 or 3 seconds and they make lots and lots of bubbles.

Then we split into two teams and practiced blowing bubbles with our cone bubble blowers.

We told the kids to see who’s team could stack the most bubbles.  We poured bubble solution into our totes and let the kids have at it.

The kids were thrilled to see who could stack the most bubbles in their hands. 

The point of this wasn’t a competition, but don’t tell the kids!  They think it is great fun to be challenged to a race.

The point was for the kids to observe how bubbles relate to each other, and what happens when they have bubbles of the same size and bubbles of different sizes touching each other.  These different sizes change the surface tension of the bubble’s ability to hold the gas inside. 

Stacking bubbles of different sizes causes lots of changes.  For example, the relationship between a big bubble and a small bubble is different than two bubbles of the same size. 

Stacking bubbles can also cause the connecting wall of the bubble to change from a sphere to a flat square shape when two bubbles of the same size meet, but the rest of the bubble remains a sphere shape. 

Bubbles always want to maintain a sphere shape to maximize their ability to retain surface tension, minimize their surface area, and hold the gas in. 

Stacking bubbles is so much fun!

Then we did a fun experiment making bubble bombs and learning about chemical reactions, carbon dioxide gas, and more.

The kids measured out a 1/2 cup of vinegar, and added 1/4 cup of water into a ziplock bag.  Then they made packets of 1 1/2 Tablespoon of baking soda wrapped in a small piece of paper towel, and dropped them into the bags and zipped them closed.  

A chemical reaction happened inside the bags when the acid (vinegar) and base (baking soda) mixed, causing lots of carbon dioxide filled bubbles.  The ziplock bags acted like balloons, filling with carbon dioxide gas.  We tried the experiment six times.   Each time we got a slightly different result.  We had bags stretch way beyond what we thought they would do.  One bag popped a small hole and slowly deflated.  Another bag sprung a leak and sprayed liquid out like a sprinkler.  The last two times we took the bombs out into the sun and the kids doubled the ingredients in the bags. The bags swelled up really fast and some of the kids jumped on the bags to make them pop!               

While the bigger kids were stacking bubbles, and making bubble bombs, the toddlers and preschoolers were also having fun learning about how to make bubbles. 

They had their own trays set up with solution and lots of different bubble wands to keep them busy.

They used fine and gross motor skills, breathing control, reasoning skills, physical activity and more.

They practiced blowing bubbles under the shelter, and outside in the sun.  There was more wind outside and it made for great fun chasing their bubbles.

This is my favorite picture from our bubble science adventure.  I love how this three year old danced and twirled in the bubbles she made.

Another experiment we did was learning about the wind using bubbles.  We marked our starting point, blew bubbles, followed the bubbles and repeated blowing and following several times.  Then using a compass, we traced our steps back to the starting point to find out the direction of the wind.

We also made some geometric shapes from recycled toy parts, and with pipe cleaners.

It was amazing all the different shapes of bubbles the kids could make with these.

They tried out lots of different bubble wands and bubble blowers and learned how to make great big, giant size bubbles as well as the tiniest of bubbles.  This may all look like child’s play to you, but these kids were really playing to learn.   That is my favorite!  Learning about life around them through the process of playing!   It was one experiment after the next.  Who knew science and investigating could be so much fun?

And they worked up quite the appetite in the process. 

It is so much fun to spend time learning, playing, and fellowshipping together.
