You all know the wonderful reaction you get when you mix baking soda with vinegar. Well we took it up a notch and created a full fledged experiment with it! Part of our chemistry curriculum is studying the scientific method and performing an experiment. Sprite wanted to test three types of vinegar and see which one would create the greatest reaction.
We used our graduated cylinders to measure out equal portions of vinegar
and baking soda
We did a few trial runs to determine exactly how to measure the reaction. We ended up timing the bubbles and measuring the distance of the foam.
Although her hypothesis was wrong, she did learn more about vinegar’s reactions. We also made the red cabbage litmus test to compare the acidity of each type of vinegar.
This was a really easy and practical experiment for us to do! I consider it a success. She took detailed notes and wrote up a nice lab report.
My boys love this kind of stuff. Anything that will blow up or make a mess. LOL Thanks for sharing.
As a former science teacher and lab researcher, I have to say GREAT JOB! I love that you took this beyond what young kids usually do and created some a wonderful science experiment!
Awesome!
I am not sure I would have even thought to try the different types of vinegar! Way to follow the scientific method! This is our first year to do a real science notebook- but my boys would still cringe if it requires too much writing or drawing. They much prefer copywork, and right now, I’ll take what I can get!
Great site! I really like the way you teach scientific methodology. It reminds us that science is fun. You take good photographs, too.
I teach science for elementary teachers (and each semester I patiently explain, again, why we homeschool)
May I use one of your images of Sprite in my powerpoints?
