Fizzy Heart Valentine Science


 We LOVE baking soda and vinegar science.  Such a simple experiment that my kids love each time we do it.  I love mixing it up by creating a themed or holiday experiment from time to time.  Also having 3 kids all different ages it seems each year it is a new experience for one of them.  This year we will finally have exposed all 3 kids to baking soda science.  I think it is a great multi aged and fun sibling activity.   We had so much fun with a Catapult Science experiment to see if we could break candy hearts I wanted to set up another candy heart experiment for the boys.  Today I am sharing our Fizzy Heart Valentine Science.

baking soda science

To start mix baking soda, candy hearts, and a little water in the small bowls.  We made 3.  Once mixed place in freezer until frozen.  Ours sat several days before we had good weather again to try it out.


Our Setup:


I took all our supplies outside.  I put a plastic tablecloth down to help with the mess.  I then placed the plastic tray on the top of the tablecloth. Take the frozen baking soda and hearts and pop them out of the bowls. Place them in the trays.  Set this up 3 times so each kid has their own. Along with the tray we had beakers and test tubes filled with colored vinegar.  We colored it with food coloring. Now for the kids to start testing to see if they could free the hearts.

 I never know what the kids will come up with or observe during a science experiment.  That makes it fun for me to see what they will do.  I had just planned on them making the candy hearts fizzy.  However, little brother wanted to save his candy by using a little vinegar and the tweezers to pull them out.  He added every last candy into a test tube.  I just love seeing his little mind at work.

 Big brother had more fun dropping vinegar onto the frozen baking soda watching it fizz up.  And baby brother, well he was just stoked to be able to do it too.

 What is happening:  Baking Soda is a sodium bicarbonate and Vinegar is an acetic acid.  When mixed together they form a carbonic acid. It breaks apart into water and carbon dioxide.  This is what causes the FIZZING!
